Frozen Raw Dog Food

Many dogs thrive on raw diets - including some who could not maintain wellness on any other type of diet. Commercial sources make these foods convenient, but you need to choose carefully.

We’ve got some good news and some bad news for dog owners who are interested in feeding raw diets. First, the good news: Some dogs thrive on these diets. Today, there are many companies offering frozen raw dog food – some with many different formulations. The diets have long been available via direct-shipping but are increasingly available in pet supply stores, too. 

The bad news: In addition to having the potential to deliver bacterial pathogens to your dog (and household), this segment of the pet food industry seems particularly prone to sloppy nutritional formulation. As a category, the diets tend to be extremely high in fat – high enough to pose a significant danger to dogs with a high risk of pancreatitis. 

While many owners credit raw-food diets for their dogs’ vibrant good health, there are specific things you should look for (and look out for) when choosing one of these diets for your dog. 

Before we get into specific purchasing recommendations, let’s talk about why people might want to feed a raw diet in the first place.

Common Traits of Frozen Raw Dog Food

Everyone should be clear about the fact that canines evolved eating diets comprised mostly of raw meat (and raw bones, organs, and other tissues from dead animals; wild canids and feral dogs still do). 

The credit for popularizing an “evolutionary-style” diet to dogs in recent decades is usually given to Australian veterinarian Dr. Ian Billinghurst. His 1993 book, Give Your Dog a Bone, made a compelling case for the benefits of home-prepared diets for dogs – and specifically, diets that were comprised mostly of raw, meaty bones, supplemented by smaller amounts of organ meat, vegetables, eggs, and so on. Many people who followed his diet-formulation guidelines saw significant and almost immediate improvements in their dogs’ health – and a revolution was underway. Commercial manufacturers of these diets appeared practically overnight.

But every type of food for dogs that’s ever appeared on the market has won a certain number of fans and foes. No matter what type of diet being discussed, divisions develop and owners argue about “what’s best” for dogs. 

You’d think that raw-diet advocates might hang together as allies; you’d be wrong. Raw feeders argue about the pros and cons of “whole prey” diets (those that attempt to mimic the proportions of meat, bone, and organs consumed by wolves), grain-containing and grain-free diets, diets that include whole raw bones and those that grind the bones, and diets containing synthetic vitamin and/or mineral sources and those that contain none. 

Given these diverging opinions, today, about all that commercial raw, frozen diets tend to have in common is a preponderance of raw meat. If other ingredients are used, they tend to be whole, raw or very lightly processed foods. Certified organic, grass-fed, locally sourced, and/or humanely raised ingredients are more commonly found in this diet category than more conventional segments of the market.

The Truth About Frozen Raw Dog Food

What’s often lost in the arguments among raw-food fans is that no diet works well for all dogs. Just like humans (whose foods dogs have been sharing for quite some time now), what some dogs thrive on makes some dogs decline, and vice versa.

Theoretically, all dogs are equipped to eat like their wild forebears: a partly hunted, partly scavenged diet comprised largely of raw meat and other parts from dead animals. But as a point of realistic fact, raw diets don’t suit all dogs. Some dogs turn up their noses at raw; others are unable to digest uncooked ingredients well. Others may lack the immune-system rigor to defend themselves from chronic exposure to the pathogenic bacteria that’s present in much of the raw meat in the food supply (at least, the raw meat that doesn’t undergo a “kill step” – more about that in a minute).

Nevertheless, products based on some version of an evolutionary-type raw diet are very popular among some dog owners. Those who are committed to feeding a raw diet often cite a long list of benefits of these diets for dogs: better overall health and vigor, fewer allergies and digestive problems, cleaner teeth and fresher breath, nicer coats, improved reproduction in breeding dogs, and greater longevity and soundness. 

This is anecdotal evidence, of course; sound, validated, generational studies comparing the health of raw-fed dogs to a population of kibble-fed dogs don’t exist. But it’s undeniable that some dogs do great on these diets! Many raw-food diet proponents stumbled upon this style of feeding their dogs after years of struggling with a dog who failed to thrive on every other type of diet – and there is no convert as dedicated as someone whose dog was sickly and is now well on a new diet.

Bacterial Concerns of Frozen Raw Foods and Solutions

Raw-food diets also have detractors, primarily for one overwhelming reason: the potential for pathogenic organisms in raw animal-source proteins to cause illness in animals and the humans in their household.

There are a number of pathogens that can be present in and/or on meat, including Salmonella spp, Campylobacter spp, Clostridium spp, Escherichia coli, Listeria monocytogenes, and enterotoxigenic Staphylococcus aureus. In more conventional types of pet food, these pathogens are rendered harmless through cooking – unless the heat-based process, whether it be extrusion, baking, or retort (canning) is inadequate. But there are also newer technologies being developed and implemented that can kill pathogens in raw foods without cooking.

Most of the largest, most successful raw-diet companies use one of these cooking-alternative, bacteria “kill-step” technologies, such as irradiation or high-pressure processing (HPP). (For more information about this, see “High Pressure Processing in Raw Dog Food,” WDJ April 2015.) 

But a few companies are raw-diet purists; they often explain that they rely on superior sources of animal proteins, strict adherence to good manufacturing practices, and product testing to ensure that their products contain no pathogens. 

We’ve seen credible evidence that dogs can (and often do) consume the most commonly found pathogenic bacteria in our meat and poultry supply (Salmonella) without developing illness. But given the state of the nation’s commercial food-processing oversight (not good), and reports of increasing populations and virulence of antibiotic-resistant pathogens, our own bias in raw-diet selection would mirror that of the American Veterinary Medical Association (AVMA): We recommend buying only those raw-diet products that have been subjected to pasteurization of some kind. This type of food is safely treated with HPP. 

Claims of Frozen Raw Food Nutritional Adequacy

Although the popularity of dog food “mixers and toppers” has been increasing, most of these are clearly labeled as just that – “toppers” – a savory topping (some promising nutritional benefits) to add to your dog’s food. With the exception of these clearly identified topper products, in the kibble or canned food aisles, it’s uncommon to find products that are not labeled as “complete and balanced diets.” 

However, this is not the case with raw frozen dog food. There are more producers of “intermittent and supplemental” diets in this pet-food category than any other. Nutritionally incomplete products are intended to provide some of the dog’s required nutrition, with the added benefit of proteins, enzymes, and vitamins that have not been reduced or altered by the heat of cooking. Some of these incomplete diets are prominently identified as such, but the labeling on others might be small (or covered with freezer frost!). 

Because the incomplete diets may contain nutrients in levels that depart significantly from those required for a “complete and balanced diet,” we recommend avoiding those indicated for “intermittent and supplemental use.” Look for a nutritional completeness claim on each label – even if you plan to feed the product as just part of your dog’s diet. Also, you must make sure that it’s appropriate for your dog’s life stage. 

“Adult maintenance” is the least complicated claim. Pay much closer attention if you are feeding a puppy or young (under a year old) dog. The nutrient requirements for “growth” or “all life stages” are one and the same, but be aware that these products must also specify whether they are formulated to meet the nutritional requirements for growth/all life stages including the growth of large-size dogs (expected to be 70 lbs. or larger as an adult) or except for the growth of large-size dogs. Large-breed puppies should be fed diets with less calcium; these would carry the claim, “(This product) has been formulated to meet the nutritional requirements for growth/all life stages including the growth of large-size dogs.” 

Proof of Nutritional Adequacy Claims

Look for products from companies that post complete nutrient analyses on their website

By law, the only nutrient levels that are required to appear on a pet food label are its minimum levels of protein and fat and maximum levels of fiber and moisture. These are provided on all food labels in the “guaranteed analysis.” 

But “complete and balanced” dog diets must also contain minimum amounts of specific amino acids, linoleic and linolenic fatty acids, vitamins, and minerals, and have calcium and phosphorus levels within a certain ratio to each other. Though these nutrient levels are not required to appear on product labels, we recommend that dog owners ascertain that pet food makers are able to produce analyses that confirm the products meet the required nutritional levels established by the Association of American Feed Control Officials (AAFCO). 

At a bare minimum, every pet food maker should be able to send you a complete “typical” nutrient analysis for all of their products. More often than not, the analyses provided show the expected levels of nutrients based on a computer analysis of the product’s formula. Preferably, these are posted on their company websites. 

We have a strong preference for foods that have been subjected to laboratory analysis to confirm that their formulations deliver nutrient levels that meet the AAFCO guidelines. This is a significant expense for pet food makers – but it’s also of significant importance for dogs.

Watch Out for High Fat Levels in Frozen Raw Dog Food

We’re not sure why this is so, but the makers of frozen raw dog foods tend to formulate them with excessive amounts of fat. This attribute is not nearly as common with the makers of cooked frozen dog foods, so we’re at a loss to explain it. These diets don’t have to be high-fat.

Here’s a wrench in the works for conscientious dog owners who check the product labels, looking for high fat levels: Remember that the guaranteed analysis on the product label lists the minimum amounts of protein and fat. The product may actually contain much higher levels than what’s listed there. Argh! This is one of the reasons why we insist that you ask companies for their complete nutrient analyses; these should list percentages that are closer to the actual amounts in the product. 

At the very least, pay attention to the caloric density of the food – the number of calories per ounce or kilogram – in the products you’re considering. In general, the higher the number, the more fat in the product. 

What to Look for in a Raw, Frozen Diet

When selecting a raw, frozen diet for your dog, we suggest that you look for products that have these attributes:

  • Treatment with a pasteurization or bacterial ”kill step” such as high-pressure processing (preferably) or irradiation.
  • A nutritional adequacy claim confirming that the product is a complete and balanced diet for dogs. For example, “This product was formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for all life stages including growth of large size dogs (70 lbs. or more as an adult).” To reiterate, we do not recommend diets that are intended only for “intermittent or supplemental use.”
  • Complete nutrient analyses for each product. Ideally, it’s clear that the reports are the results of laboratory analysis of the products, rather than the nutrient levels expected from a software analysis of the product formula.
  • Fat levels that are not excessive. We recommend products with protein levels that are about twice the levels of fat for most dogs. Foods that contain more fat than protein should be avoided – especially for individuals and breeds that are subject to pancreatitis (for more about this risk, see “Signs of Pancreatitis in Dogs,” July 2021).

Devoted to Raw Dog Food?

If this type of diet has proven to really suit your dog – perhaps he’s had some health issues that have resolved on a raw dog food diet – we’d suggest reading another article with even more details and cautions. See “The State of the Commercial Raw Diet Industry,” WDJ September 2015, for even more in-depth recommendations. 

If you’re just trying products from this category – perhaps in an effort to resolve some ongoing health issue for your dog – or using them as part of your dog’s rotational diet, these tips should help ensure you are buying the better products in the category.

As with every change of diet, start slowly and convert your dog to his new diet gradually, watching carefully for any signs of digestive distress (such as vomiting, diarrhea, blood in the stool, or lack of appetite). Use particular caution with dogs who are prone to pancreatitis – and retreat to your dog’s former diet if you observe any  of the above-listed signs of dietary intolerance.

  1. I work in the pet nutrition industry and find this article to be slanted against feeding a raw diet. The FDA requirement for dog raw foods is much higher than for humans when it comes to pathogens, bacteria, and samonella, etc. FDA has a standard of 20 percent for human raw while dogs is less than 1 percent. I don’t recommend anyone going to their butcher to buy raw meats to feed their dog because of this, however, the manufactures of raw dog foods have stricter and higher requirements. It seems the author of this article could do more investigation before writing a slanted article.

    • I agree. I’ve been feeding my dogs raw food for years without any problems. And they provide nutritional profiles for any of the foods when I ask them. My vets don’t like raw food, but my dogs are healthy because of it.

  2. Wow, I read this article carefully. I have fed raw since 1997 to my golden retrievers, of which in that time, I’ve never had fewer than a dozen, all ages, but mostly pensioners, and no problems with the diet, ever. Ever. I found the article to be biased, rather strongly, against raw feeding. From my six-month-old to my fifteen-year old, all my dogs do well on a properly balanced raw diet. Organic, sustainably and humanely raised, small farm sourced, not HPP, plus local eggs and fish. I even feed some kibble since Covid, although ideally I would not. It is, by the way, just as expensive to feed as raw, if you’re buying the better brands. So my dogs eat everything, live long lives almost always, and seem well and happy. They don’t suffer, and have never, from all the issues warned of so direly in the article. These potential issues are so underscored that the subtext running through the entire piece is: “Don’t feel bad if you don’t/won’t feed raw; it’s not so great at best; and it’s fraught with dangers you must be ever on your guard against. Is it really worth the risk?” Re-reading the kibble reviews in past issues, I found a whole different subtext, which was, basically, some kibbles are bad for these reasons, let us now leave those behind and look at the good ones. Even some cheaper, honestly and objectively not-so-great kibbles are evaluated as if they’re worth feeding (a good practice for the sake of those with budget constraints).

    Now obviously, the article’s author has decided against raw feeding. Fine. I don’t take it as a personal rebuke any more than kibble feeders should take it as a criticism of them that I have fed raw so long to so many. (They do, though; usually they act as if I’m berating them just by stating the fact.) However, I think the editor should choose an experienced raw feeder to write this article in future, just as an experienced kibble feeder writes the kibble evaluation in February’s issues. Because were I someone interested but not experienced in raw feeding, and I read this article, I would definitely decide against raw.

    • Hear, Hear!! I totally agree. I have fed raw meat/fish/protein products to my dogs for two decades. No issues (except w/vets who do not understand & these types of articles). This information is not helpful to those who feed otherwise as there are never any resources, literature, solid findings referenced to back up these claims & statements. I am tired of explaining things to a vet (w/no nutritional training beyond the Science Diet & other cans/boxes in the waiting room). I truly expected better from WDJ especially as I have all the old articles extolling the virtues of raw green tripe which started me on this years ago & thanks to Tom Yeager at Green Cuisine for Pets (recently sold), I found my GSD to have EPI & the frozen tripe products were outstanding. I now blend veg, eggs, fruit, other proteins & products from My Pet Carnivore to the delight of our current rescue shepherd who is thriving. I also returned to Kimberly Gauthier online who presents great info on feeding. Thanks for your comment; I was thinking ‘Oh, here we go again’ & as Kimberly advises (which I haven’t pursued), we need to get in touch with all the amazing people online who raw feed for support, ideas, recipes, & kinship. Best to you!!

      • Sherry I would so like to visit with you regarding your diets for your shepherds. I am totally frustrated with the path bets are taking me with a rescue

  3. I agree with Ms Doyle. The article on raw diet is very biased. I have always trusted WDJ for good information regarding the health of dogs, but seriously doubt the author’s intention of presenting an unbiased review of the raw diet. Having started my journey with the raw diet due to an immune system compromised Weimaraner and honestly believe it improved his quality of life and was responsible for his lifespan of over 15 years, enabling him to compete and earn titles in almost all available venues offered by the AKC (he was not a conformation prospect).
    I sincerely hope that this article will not turn away anyone interested in pursuing a better alternative diet for their dogs than overcooked kibble. Having used this raw diet for over 25 years on rescues, foster dogs, and my own dogs and puppies I stand by my choice to better the life of the dogs I have had the honor to love and care for.

  4. I have fed my two border collies a frozen raw diet for their entire lives with no problems what so ever. They are now ages thirteen and eleven. They have been healthy happy and growing old gracefully. So don’t take this article to heart. Do your own research if your interested in feeding a raw diet. I’ve never regretted it.

  5. I disagree I do not think this article is trying to talk anyone out of raw diet.. They are suggesting to look at labels etc… I checked my dog food to see exactly if this does fit the recommendation they suggest and it does.
    My dog has had many issues from puppy to her first year when we finally decided this is crazy and started her on raw. She was underweight and losing still or at least not gaining.
    For the first time she ate it all up in one sitting which she has never done. There is the odd time she does not eat it all but is rare these days. She is now 3 years old and is healthy and maybe slightly over weight… which I thought would never happen. Like most of you I have not regretted the decision of raw either… I did not get the feeling from this article they were against it.

    • The article did make a number of useful and valid points. You shouldn’t feed raw cluelessly, nor should you feed kibble cluelessly. However, I was keyed into the author’s tone, or attitude toward the subject. I got the strong impression that the author does not and would not feed raw. She seems to view it as a diet of last resort, which is how many people (yourself included, apparently) come to it. WDJ used to have a much more positive attitude toward raw feeding, but in recent years, not so much.

  6. One plus of raw feeding is way smaller poops to pick up. For country dwellers, not a make or break, but it does indicate the extra waste excreted that does NOT feed the dog in dry dog food. Bacteria has never been problem for us ( about 20+ years of a wide variety of raw meats, fish & eggs& VM supplementation), merely normal cleanliness. The big problem for raw feeding is the anti bias of many veterinarians. Most vet schools preach the horrors of raw feeding, and vets are not given a fair & balanced description of this method of feeding. It is not clear to what extent vet schools accept donations from Kibble Korporations. Many veterinarians do sell kibbles so have a vested interest in promoting dry food and slamming raw.

  7. I have fed various dogs raw for over 20 years. Our journey started thanks to our rescue husky who just never thrived an even the „brst“ kibble. I dud research and decided that about 50 yrs ago or so huskies were put out in the summer to hunt and forage for themselves so kibble was probably not on their menu.
    We have never looked back. We have revived to thriving several rescue dogs from small to giant. We have raised several foundling puppies to strong and healthy dogs.
    As for kibble not having any bacteria, i think that‘s a bit if a fallacy because it has meat and is open to air.
    We buy our dog‘s food in 40 lbs frozen bags (chicken backs etc) as well as ground frozen organ meat.
    We defrost as needed and feed it to them.
    We add fresh vegetables,occasional eggs and oatmeal. Never had any issues. They are healthy and thriving.
    I think you need to have separate cutting boards and wash your hands after handling raw foods, but who wouldn‘t?
    I personally am vegan but i have realized that my dogs thrive on this diet…
    I too did find this article biased against raw. It makes it sound difficult and dangerous.

    • No. Many people say this, but there is no evidence for it. Owing to the supply chain issues of the pandemic, I was doing this for over a year, no problems, not that I anticipated any. I honestly think the claim is totally illogical.

  8. Don’t forget that the FDA has a zero tolerance policy for pathogens such as salmonella. These raw food companies know it, and that they are at greater risk of penalties than the kibble foods, and they have to be far more diligent about preventing a run-in with the FDA. (even though kibble has at least as many if not more salmonella problems, and has a greater history of sickness and death as a result)…I remember the recall of thousands of pounds of kibble at Diamond pet food for salmonella that killed at least 6 animals and sickened at least 14 people. That was an extreme case, and the truth is that salmonella affects people far more often than dogs, as dog’s have a physiology designed to handle it.

  9. There’s are so many raw food companies not doing the work it takes to keep the food safe, nutritional or sourced properly.
    I feed All Provide to my 3 Border Collies and couldn’t be happier with the product, the company & the service.
    We need to do our homework & sadly I don’t think it’s in this article.

  10. Two comments.
    First, I’ve often wondered if the reason many vets won’t recommend a raw diet is fear of being sued by an unhappy client, especially since the vet doesn’t have many studies to refer to and back him up.

    Second, the reason those studies haven’t been done is because there isn’t any money in it for the big commercial dog food manufacturers. Besides, why would they want to promote something that would compete with their kibble business?

    As with almost everything, follow the money trail and there’s your answer.

    • I will address the first question, as I know many vets, and at least thirty have acquired golden retrievers from me, often because I feed raw. Most of them sell Science Diet or Purina in their lobbies (not the specialists), but feed their goldens from me a raw diet. It is a liability thing. If they recommend raw, and the client makes a mess of it, they fear blame. This has never actually happened, to my knowledge, but I understand their concern. It’s interesting, because there have been several significant recalls of kibble and canned foods for contaminations that caused illness and death in dogs, (mostly fungal, but there was that recall of an expensive canned food that was determined to be euthanized horse rather than beef), and vets might well have recommended some of these products, but vets were not blamed for this, manufacturers were. However, most people would not have fed raw had it not been recommended by someone, so. Vets often have a fairly low opinion of the general public’s ability to follow direction. I think the best way to deal with it is to give curious clients lists of websites and publications of raw feeding experts, and say, “I’m not an expert in this, but here are some resources if you’d like to pursue it.” That puts the onus and responsibility where it belongs, on the actual dog owners.

  11. I have been disappointed with WDJ for years for not testing and rating commercial raw food diets. This article somewhat explains why this has not happened: Nancy Kerns does not approve of a raw food diet. A response several years back to my complaint of no raw food review said there was a conflict of interest as Steve Brown (Steve’s Real Food) was on her Board or a contributor or some close association. If I am correct, he no longer owns that company. I have read that some 10%-12% of dogs are fed commercial raw (although that may include home prepared diets). Surely we deserve an unbiased rating of available products.

  12. Even though I feed raw (currently a raw commercial diet), I didn’t react as strongly as some of the comments I’ve been reading. As Nancy points out, different dogs need different diets. Even before reading this article I had become aware recently of how ridiculously high in fat this supposedly good quality product is I’ve been using for years. With my now senior dog, that is starting to cause GI problems. Having said that, I do prefer a less processed food and can’t feed him kibble due to all his food sensitivities. (Yes, he developed those even on a raw food diet). I really don’t think folks need to be concerned that one article is going to turn people off of pursuing a raw diet. It just encourages me to continue to do my research on finding a better food for my dog.

  13. Excellent article, Nancy. Fair and balanced. I fed raw (generally home prepared) for many years and my dogs did wonderfully well on it. I raised litters, finished Champions, did well in performance and my dogs lived long healthy lives. Many of my puppy buyers also fed raw successfully. Age, the problem with carrying 40# cases of chicken parts down steep basement stairs, and the loss of one of my suppliers finally had me switching back to kibble. I was never anti-kibble, just felt it was better to feed my dogs raw when it was doable. Because we don’t feed organ meats to Dalmatians (the purines can cause urate stones) the one-size-fits-all mentality made commercial raw impractical. My dogs are doing well on kibble, but their teeth are not quite as pearly white, I’ve encountered my first case of anal gland issues, and the stools are much larger and smellier. Raw fed stools are small, dry and almost odorless – I miss that. But, my dogs are doing well on kibble and I still mentor aspiring raw feeders and consider it an excellent option for dog owners.

  14. We are Dog loving company. Our all product is made with Pure Buffalo, Sheep & Cow full-grain leather. These are durable raw materials and are assembled with premier craftsmanship & stitch with recycled thread.

  15. Loved reading your comments in the whole dog journal regarding frozen food diets. I am so for that but have been reluctant to start because of those pathogens they talk about. So, I went with Dr. Marty’s food. this is food that is processed with biologically balanced nutrition. My woof loves the stuff and she seems to be doing well. So, that’s my story. would really appreciate your thoughts and yes, after reading everyone’s feelings concerning the frozen stuff. I will get some. Thank you for your time.
