The Importance of Clipping Dogs' Nails

Why keeping a dog’s nails short and sweet should be a top priority for all dog owners.

[Updated November 13, 2017]

Let’s get this out of the way first: Nobody, it seems, likes to “do” dog nails. Not you, not the dog, nor anyone else who may be called upon to take on nail-clipping for you (such as a technician at your local veterinary hospital or even a professional groomer). But for the health of your dog, it must be done, and should be done frequently enough to keep your dog’s nails short.

This isn’t an article about how to make nail cutting a more pleasant experience for you and your dog; this magazine has run plenty of those. Don’t be tempted to skip that step: You should read up on positive reinforcement and desensitization techniques before you even think about snipping; of course your dog should be comfortable with having his feet touched and manipulated before you attempt any type of nail trimming. If he is not – and especially if he shows signs of serious distress or aggression – consult a qualified dog behavior specialist to help you modify this behavior. Better safe than sorry.

No, this article is what you’ll need to know before you have appropriately and positively introduced your dog to the nail-cutting experience. I hope to convince you to commit to a regular nail-maintenance program for your dog.

Long hair on a dog’s feet can hide a really painful situation with too-long nails. Keep your dog’s hairy feet clipped, or check the length of her nails weekly.

Why Dogs Need Their Nails Trimmed

When dogs spend a good deal of time outdoors, running on various hard surfaces, including concrete and blacktop, their nails are gradually worn down, and they have less of a need for formal nail-grooming sessions. But today, with many suburban and urban dogs increasingly confined indoors when their owners are at work, and running mostly on soft surfaces such as lawns when they are outdoors, this welcome friction is often absent in their daily lives.

Long, unkempt nails not only look unattractive, but over time they can do serious damage to your dog (not to mention your floors). When nails are so long that they constantly touch the ground, they exert force back into the nail bed, creating pain for the dog (imagine wearing a too-tight shoe) and pressure on the toe joint. Long term, this can actually realign the joints of the foreleg and make the foot looked flattened and splayed.

Again, this isn’t just an aesthetic problem, it’s a functional one: Compromising your dog’s weight distribution and natural alignment can leave her more susceptible to injuries, and make walking and running difficult and painful. This is especially important in older dogs, whose posture can be dramatically improved by cutting back neglected nails.

It’s much easier to trim white nails nice and short, since you can see the pink, sensitive tissue inside the nail, and stop short of cutting into this and causing it to bleed.

In extreme cases, overgrown nails can curve and grow into the pad of the foot. But even if they are not that out of control, long nails can get torn or split, which is very painful and, depending on severity, may need to be treated by a veterinarian.

And in the end, unattended nails create a vicious cycle: Because the extra-long nails make any contact with his paws painful for the dog, he avoids having them touched, which leads to unpleasant nail-cutting sessions, which makes both human and dog avoid them, which leads to longer intervals between trims, which leads to more pain …

The Basics of Clipping Dog Nails 

So what’s the goal? What’s the “right” length? While some breeds (most notably the Doberman Pinscher) are often shown with nails so short they can barely be seen, the most commonly accepted rule of thumb is that when a dog is standing, the nails should not make contact with the ground. If you can hear your dog coming, her nails are too long.

The nails of mammals are made of a tough protein called keratin. Technically, dogs have claws, not nails, though we’ll use the latter term in its colloquial sense for this article. (The distinction is that nails are flat and do not come to a point. And if your nail is thick enough and can bear weight, it’s called a hoof.)

Dog’s nails differ from ours in that they consist of two layers. Like us, they have the unguis, a hard, outer covering in which the keratin fibers run perpendicular to the direction in which the nail grows. But unlike us, under their unguis, dogs have the subunguis, which is softer and flaky, with a grain that is parallel to the direction of growth. The faster growth of the unguis is what gives the dog’s nail its characteristic curl.

Plier-type clippers need to be sharpened occasionally to be effective. Replacing the cutting blade on guillotine style clippers (right) is easy, but operating this tool is daunting for some people.

In addition to one nail at the end of each of the four toes usually found on each foot, many dogs also have a fifth nail, called a dewclaw, on the inside of the leg, below the wrist. Some dogs are born with dewclaws in the front only; others are born with dewclaws on every leg. There’s a great deal of debate about whether these should be surgically removed; some breeders do this a few days after birth because they believe that the dewclaws are vestigial, and are likely to rip or tear if they are not removed. (Many shelters also do this surgery on dogs at the same time they do spay/neuter surgery.)

Proponents of dewclaws argue that dewclaws are not vestigial, but indeed used to grip objects such as bones, and to provide important traction when a galloping dog needs to change direction. (Poke around Youtube and you can find videos of Sighthound lure coursing; they actually lay their entire forearms perpendicular to the ground when redirecting their momentum.) Even the floppy double-dewclaws of breeds like the Great Pyrenees are said to have some purpose (traction or a “snowshoe” effect in the snow).

One thing is certain: If a dog has dewclaws, they need to be trimmed – perhaps even more often than nails that routinely touch the ground. Because the dewclaws rarely touch the ground and so aren’t worn down, they tend to be pointier than the other nails. But perhaps because dewclaws are so loosely attached to the forelimb, many dogs object to trimming them much less.

The Canine Toenail Quick

There’s a reason why the phrase “cut to the quick” means to deeply wound or distress: Running through the nail is a nerve and vein called the “quick.” Nicking or cutting this sensitive band of tissue is very painful for the dog – and messy for the owner, as blood often continues oozing from the cut nail for what seems like an eternity. (Keeping a stypic-powder product, such as Kwik-Stop, on hand can help promote clotting and shorten the misery. Or, in a pinch, try flour.)

Shortening the nail without “quicking” the dog is easier said than done – unless your dog has white or light-colored nails, in which case, you’re in luck: The quick will be visible from the side, as a sort of pink-colored shadow within the nail. Avoid going near it. If you trim the nail with a clipper or scissors, trim a bit off the end of the nail, and notice the color at the end of the nail (in cross section). As soon as the center of the nail starts to appear pink, stop.

You can’t see the quick in a black or dark-colored nail. With these nails, you have to be even more conservative about how much nail you trim off. After making each cut, look at the cross-section of the nail. If you see a black spot in the center – sort of like the center of a marrow bone – stop cutting. It’s likely your next slice will hit the quick.

The longer a dog’s nails are allowed to grow, the longer the quick will become, to the point that taking even a very small bit of nail off the end “quicks” the dog. Then the goal becomes a matter of snipping or grinding the nails to get as close as possible to the quick, without actually cutting it. This is perhaps easiest to accomplish with a grinding tool (such as a Dremel), though it can be done with clippers, too, with practice. By grinding away the nail all around the quick – above it, below it, and on both sides – the quick has no support or protection, and within days it will begin to visibly recede, drawing back toward the toe.

If a dog’s feet have been neglected for months (or, horrors, years) at a time, it might take months to shorten those nails to a healthy, pain-free length. But if you keep at this regularly, it should get easier for the dog to exercise. And the more he moves, the more his nails will come into contact with the ground in a way that will help wear the nails down and help the quicks to recede.

Helpful Trimming Tools

Nail clippers use blades to remove the tip of the nail. There are a couple of different styles to choose from, but no matter what type is used, their effectiveness is dependent on the blades being sharp and clean.

Guillotine trimmers have a hole at the end, through which the dog’s nail is inserted; then, as the handles of the tool are squeezed together, an internal blade lops off the end of the nail in a fashion reminiscent of the execution device for which the trimmer is named.

Some people find it easier to chop through thick nails with these clippers, but others find it difficult to thread each nail through the hole at precisely the right distance from the end of the nail, especially when the dog is wiggling or uncooperative. On the plus side, though, it’s fast and easy to replace the blade in guillotine-style clippers – in fact, most guillotine clippers are sold with replacement blades, which encourages an owner to swap out the blade as soon as the tool loses any effectiveness.

Scissor- and plier-style trimmers are arguably easier to use, but need to be sharpened from time to time – and who knows how to do this, or where this service can be obtained these days? Many people find themselves discarding and replacing these tools as needed, instead.

The Dremel 7300 and Dremel 7300-PT (bottom): We’re pretty sure the pawprint on the case is the only difference.

Grinders are relatively new to the world of canine manicures. So many owners discovered how easy it was to use that old hardware standby, the Dremel tool, that you’ll sometimes hear that brand name used as a verb, as in “I Dremel my dog’s nails.” Soon enough, pet-specific rotary grinders found their way to market – and now Dremel makes a pet-specific grinder, too.

Regardless of the type of grinder you buy, make sure it is appropriate for your dog. Some cordless models might be perfectly adequate for a Papillon, but simply may not have enough oomph for trimming the thick, hard nails of a larger breed like a German Shepherd.

Though Dremels and other grinders come with several different attachments, most owners opt for the sandpaper barrel. Change the sandpaper sleeve whenever you see it’s becoming worn.

Be sure to acclimate your dog to the sound of the grinder, and then slowly introduce the tool, so that your dog is accustomed to the grinding sensation on his nails. Don’t keep the rotary tool stationery on one area of the nail, as the heat it generates can be painful for the dog.

Be aware of dangling hair – both yours and your dog’s – and take care not to have it get entwined in the tool’s spinning drum. To protect your eyes, wear safety glasses. And because nail grinders can generate a good deal of nail dust, a disposable surgical face mask is a sensible idea as well.

Nail Maintenence Routines are Crucial

If this sounds like a lot of work, it is – at least initially, until you and your dog develop a nail-maintenance routine. And “maintenance” really is the name of the game; it’s far easier for you (and less painful for your dog) to maintain his short nails than to shorten nails that have gotten long, with the inevitable corresponding long quicks.

If your dog’s nails have gotten too long, or you adopted a dog whose nails were too long, you need to really commit to frequent trimming to restore his foot health and comfort. Three to four days is probably the minimum amount of time that’s advisable between salon treatments that are intended to encourage the quicks to recede. Once a week is ideal if you want to gradually shorten your dog’s nails and eliminate all that clickety-clacking on your wood floors. And, depending on the rate at which your dog’s nails grow (and what sort of surface he exercises on) once or twice a month is a reasonable goal to maintain the nails at a healthy length.

No matter what frequency you choose, make a commitment. Earmark a specific day of the week or month for your grooming sessions, and stick with it. You’ll have a better chance of remembering to do your dog’s nails on a regular basis if you get into a routine.

trimming dog nails

When using a nail grinder, make sure you pull all the dog’s hair out of the way. The sandpaper can catch stray hair and cause the tool to spin into the dog’s foot, causing serious pain and injury to you and your dog (not to mention, traumatizing your dog for future nail trimming).

It may also be helpful to dedicate a location in your home for doing your dog’s nails – somewhere comfortable for you and your dog and with a good light source. Make sure you have everything you need at hand before you begin: clippers, styptic powder and some tissue or a small clean towel or washcloth (in case you accidentally quick the dog), eyeglasses for you (if you need them to see well up close), and lots of small, high-value treats to keep the experience rewarding for your dog.

It’s also smart to have a leash on your dog, even if he’s usually fine with having his nails clipped; many dogs will attempt to leave abruptly if they are “quicked.” And who could blame them? If you do  make a mistake, don’t make a huge fuss. Feed your dog some treats, and proceed with more conservative clips.

Hi all
My dogs nails are quite long, he is an eleven year old cross breed weighing 20kg and quite livley. The vet has never made a thing of his nails, apart from once when they cut/trimmed them about 2 years ago.
I now do them myself and have a grinder/dremel battery tool which he is okish with, but in places the nails seem hollow, or part is hollow if that makes sense and have chipped in places when on walks.
Question is, do the nails feel sensitive afterwards, either from the grinding or the fact they are shorter? Reason I ask if a couple of times he hasnt possibly been 'quite right' when walking later that evening on those legs.
Bearing in mind I dont think ive actually got near the quick, but more until they dont look hollow any more.
Many thanks in advance for any advice.

I have a strong willed GSD pup.I started introducing the Dremell on week one when he was 11 weeks old for weekly sessions. He loved the positive approach until I didn't get anywhere besides running the Dremell and feeding the little prince treats. He threw in the towel when he felt that he had to undergo this"torture,". Since it has to be done, I decided to just do it and held him tight. It was a rodeo the first two sessions until he suddenly relaxed and gave up. Now, at 5 months old, he quietly lies down without me having to restrain him. So the approach needed also is dependent loo on the nature of the individual dog.

Great article. Cutissuesting your dogs nails is also about posture. Dogs with long nails tend to walk funny and develop joint. I another great article written about nail trims was also done by Lori Nanan - Nailed it

I'm interested to know how wolves or wild dogs would have shorter nails than city pooches that do lots of running around on hard surfaces. wolves and wild dogs would spend most of their time on soft, permeable surfaces.

Out of interest i googles some wolf feet photos. their nails seem quite long....

Our appointed day is Sunday....like clockwork. My 15 year old beagle HATES the grinder but hates the nippers even worse. It is best to get down to business and get it over with quickly and then hand out the yummy treats. My 20 month old English Cocker is much better about it. I didn't get the beagle until she was 2 and by then the window was closed to make it an okay experience for her She shakes like a leaf while I am doing it, even though I have never quicked her so I try to be consistent and brief--it is the kindest way. I can keep it brief by attending to them weekly and never letting her nails get long and the puppy (whom I started acclimating to the grinder when she was 9 weeks old) needs the frequent exposure so she doesn't develop any nervous habits.

I've always been afraid of cutting my dog's quick. I'm on my third rescued lab, and I've never felt comfortable with the guillotine clippers, and my dogs hate Dremels. I invested in a pair of really strong, high quality, sharp human toenail clippers. They allow me to clip small bits at a time, so I can see when I'm approaching the quick. The dogs also seem more relaxed when I use the human clippers, I think because it exerts less pressure. Bits of frequently dispensed chicken help too. :)

IF every shelter and breeder would INSIST that the adopter or buyer GET a LESSON on doing their dog or puppy's NAILS - BEFORE they could take them HOME (as my first breeder DID) - how much better off.... would everybody BE? It is STRONG motivation coupled WITH HELP - from a knowledgeable source.

As to dogs who struggle or even HIDE the limbs - as a poster mentioned - have they ever tried hooking dog up with a leash to say an immovable object (like the fridge) and then doing one foot at a time (turned UNDER) as though you were a blacksmith shoeing a horse? (Having Weimaraners, I LEARNED a long time ago NOT to let a smart or determined dog => OUTSMART me).

If the leash is short (or TIED short) & the dog is "pinned" via your body to a wall or cabinets, it means far LESS struggle or wiggling. It is hard to move or "DANCE" (NEARLY AS MUCH) on 3 legs with the 4 being held. If YOU have bad knees either used a kneeling pad & kneel on the floor (cheap option) like you would planting flowers OR get a GROOMING table, esp for smaller dogs. Sometimes all you need is the grooming table non-slip SURFACE, which could be popped on a kitchen island if not a crate or lower table. If you do not have HELP, then again using the grooming noose (that normally comes with a grooming table) or tying doggie UP but NEVER leaving their side (so they cannot JUMP OFF and/or strangle) is a requirement. Yes, that also means getting all supplies lined UP first.

I like still like flipping the dog over on its back (between my legs) and doing them on a carpeted floor, under a strong floor lamp. (Thighs are very strongly muscled on EVERYBODY, no matter WHAT your fitness level is, A-hem!) I ALWAYS give super wonderful treats - AFTER each paw is completed. And a few additional, when the entire JOB is done.

A tip I learned long ago.... when cutting/grinding nails that are black take a small flashlight and hold it behind the nail and you will be able to see where the quik ends. Good Luck!

I'm surprised no one has mentioned broken toes and broken nails. Having neglected nail trims too often over the past 20 years many times I've noticed a toenail at an angle instead of pointing forward. Eventually I realized the toe had been broken and healed.

Broken nails (and those cut too short) are a pathway for infection. I was fortunate to learn this as one dog had clear nails and I was able to observe a growing black streak inside a nail. Thankfully an oral anerobic antibiotic was able to heal the infection.

Also, a dogs nail while dense near the tip becomes a porous honeycomb nearer the quick. To prevent infection apply a No-Sting sealer like paw wax, bees wax, etc with non-volatile ingredients. If Not Sensitive a sealer like silicone adhesive, instant glue or toenail polish can be used.

ps: for the dog chewing her feet.. other than the logical foot injury, a dog may do this when there is an itch or pain elsewhere that can't be scratched/licked,etc. Allergies are thought to be one cause of foot licking/chewing.

and to Regina Notman, dogs obsessively licking or chewing on feet is usually allergies. Wheat is a common one. I also had a maltese who broke out if she ate beef. Check your food and start with one that has just a few ingredients (this is where lamb and rice started out). Good luck!

Tip: Do the nails after a bath, they are much softer, which makes less pressure on the nail when you clip it, and it doesn't bother the dog as much. Also for those who dremel (and most of you prob. know this), don't put the grinding wheel right up to the tip of the nail and hold it there while it grinds away. Instead, hold it to the nail briefly as you go *around* it - top, bottom, sides - like bzz, bzz, bzz.

I enjoyed the article very much. I'm sorry others found it useless. Perhaps rather than criticizing they could become a contributor and share their wealth of knowledge. I've never had much of a problem clipping my dogs nails until I adopted a rescue who evidently had all his clipped way too short. Slowly and with treats we have overcome the snarling and biting. Because his nails are dark I clip weekly and just a little at a time.

I appreciate this article so much, we have a huge Lab that hates her feet touched at all and getting nail clipped are just about impossible for groomer, or anyone else. I will try all your suggestions. I have a question for anyone that can answer. Winter our huge lab chews her feet obsessively, why? We have tried sprays from the vet, seem to bring relief if we can force her to spray them. She is chewing between her pads, which are very rough.
We also have a rescue, his name is Chris, sweet animal but has only had his nails clipped once. We took him to a groomer. The groomer said he did fine, he is one with black nails, would it be possible to do his twice a week until they are at a reasonable length? So grateful for your article!

Mostly a useless article - "you should have desensitized your dog first!) If we
are here reading this article, it is because we understand that dog's nails must
be clipped. Therefore, a quick, thorough how-to with a photo of the "quick" would suffice.
Are you paid by the word???

I have found that a cat claw clipper works better on the nails of small and even medium size dogs as it is easier for me to see and position the nail with the smaller tool. If I have to apply too much pressure to cut, though, then that is a sign I need to go with a larger clipper.
I have one dog that I've had for 10 years, since she was about a year old. It took me months to get to the point where I could trim all her nails in one sitting and even now she is convinced that each time might be "the time" that I end up cutting off a toe....I use lots of treats during the process and sometimes end up putting her in a "sheep hold" (cradling her upside down in my lap as if fleecing a sheep) and somehow this calms her down and she stops struggling.

I made the "dreaded mistake" of just going too close to the quick once and my dog has not allowed me near her nails again. If I try she hauls her body over her feet so that I cannot touch them and then gives me THE LOOK. You know the "Go ahead and try, I dare you" look. If I do try she feigns aggression because this is the sweetest dog on earth, but I respect her wishes and so I bring her to an experienced groomer who she feels very safe with and I take her every 5 weeks. Based on this article, I guess I need to bring her more often.

"they actually lay their entire forearms perpendicular to the ground when redirecting their momentum."
Don't you mean 'parallel'? Their legs are perpendicular to the ground when they are standing still.

Thank you for this article. I carefully and slowly trained my three German Shepherd Dogs to the Dremel starting when they were puppies but it can be done at any age. My dogs' nails are so thick and tough it would be cruel to use a clipper. Nail trimming day (every Thursday) is the only time they get to be on the couch so it is special. In the beginning it was, "Head stays down, Mindy gets a treat." Repeat, repeat, repeat. At first be happy when the dog lets you touch her feet. Praise, praise, praise. Gradually touch the (turned off) Dremel to a toe and rub the sandpaper on the nail. Give another treat. Touch another nail. Let her sniff the Dremel. Take a break (go run and play) then start again. Eventually hold the Dremel at arms length away from the dog and turn it on to let him get used to the noise. Praise and treat. Make it fun and happy. Touch a nail with the turned on Dremel, move it away, praise, praise, praise. It may be days or weeks until you can do all nails in one session. Listen to your dog. If he snatches his foot away, let him. Do not make it a tug of war. It is his foot, respect him. Go slowly, praise and pet. One of my dogs is most sensitive on her back toes so I do those first. One dog wants to lie on his chest and watch - ok as long as he keeps his nose back! Another lies flat on her side and pretends it isn't happening. I can do the nails of all three dogs in less than half an hour. As you grind look at the trimmed end of the nail frequently. Get to know your dog's nail conformation and you will learn when you are getting close to the quick. Then smooth the edges. All done? Party time!
