Dog Food Information

What is digestibility and why does it matter? Digestibility reflects a food's ability to deliver essential nutrients to the dog who eats it. This ultimately affects not only defecation quantity and quality (how much your dog poops and how the poop looks and smells), and a dog's propensity for flatulence (no explanation needed), but more importantly, a dog's long-term health and wellness. The graphic on this page summarizes how digestibility is measured using feeding trials with dogs.

The easiest type of bowl to keep clean – and, not incidently, also the safest bowl for your dog to eat and drink from – is stainless steel. This material will not leach potentially dangerous chemicals into your dog's food and water, like some plastics, aluminum, poorly glazed pottery, or old ceramic dishes. Stainless steel and glass bowls are similarly inert, but stainless steel wins in my house, due to its durability on the floor and in the sink.

We'd love for you to take our dry dog food selection criteria into account as a starting place – only that, though, because there are a lot of other factors that people take into consideration when buying food for their dogs, and everyone will weigh these factors differently, depending on their individual needs and beliefs. If we made up a pie chart illustrating the weight of these factors, each dog owner's important food buying factors" chart would be different

Vitamin D deficiencies in dogs can cause health problems over time, but so can an oversupply. Because vitamin D is fat soluble, it accumulates in body fat. Overdoses can be toxic and even fatal, but some vitamin D is necessary to a dog's health. Vitamin D will aid in the absorption of calcium and phosphate, increases bone cell activity, influences the formation and growth of long bones, and speeds the healing of fractures. Adequate D levels may help prevent heart disease, joint inflammation, skin and coat problems, cancer, vision problems, depression, mental illness, infections, inflammatory bowel disease, dental problems, hyperparathyroidism, and kidney disease.

Every aspect of an AAFCO feeding trial is meant to ensure that a food is capable of maintaining a population of a minimum number of dogs for a minimum period of time (26 weeks for a maintenance" claim; 23 weeks for a "growth" claim). At a minimum

Free feeding is the practice of making food available to your dog at all times. Convenience is typically cited as the reason why owners choose free-feeding. Being a responsible dog owner means doing what's best for your dog not what is convenient.

When WDJ first reviewed dog food, back in 1998, there was but a handful of companies making what we considered good foods. Seriously, I stretched to find five companies that had products that contained only good-quality ingredients - and more importantly, didn't contain unnamed animal fats and meat by-products. And just about every question I asked a pet food company was answered with, "I'm sorry that's proprietary information!"

The long-term goal of this column is to teach interested dog owners how to formulate safe and wholesome complete and balanced" home-prepared diets for their dogs. We will eventually cover raw and cooked diets

I will occasionally use a bowl, but increasingly my dogs' meals are experiences! One option is a kibble-dispensing ball for each dog, with a closed baby-gate between them to prevent my Cocker Spaniel from stealing the Shepherd-mix's ball when she's done with hers.

Like us, our dogs need both physical exercise and mental stimulation. As a trainer, I see many clients who focus on physical exercise, but don't always consider the benefits of mental stimulation—what I call brain-work. One easy way to add in a bit of brain-work is to get rid of your dog's food bowl and replace it with other fun feeding options. I'm always so excited to share with my clients how fun and effective it can be to ditch the dish! Yes, that's right: Throw that traditional food bowl into the trash and get going with creative feeding.

Pet food manufacturers are fond of saying that their operations are highly regulated. It's true that regulations are in place that, in theory, protect consumers' dogs against poorly formulated products – but it's also true that there is little surveillance and enforcement of the regulations. Rarely (and usually only in response to complaints) do regulators test to see if a food meets the guaranteed analysis for macronutrients on its label, and even more rarely, if it meets the standards for vitamins and minerals. So it's largely up to the market to look after itself.
