How to trim your dog's nails at home without hurting them

Key points

• If the nails touch the floor while your dog is standing, it's time to trim them: usually every 3-6 weeks.
• Inside the nail there's a blood vessel and a nerve (the quick); on black nails, cut thin slices and stop when you see a dark dot in the center.
• Keep styptic powder handy: if a nail bleeds, apply pressure for a couple of minutes and it usually stops.
• Don't forget the dewclaw, which doesn't wear down and can grow into the skin.
• Nails that grow very thick, curl or break on their own are worth a vet visit.

Trimming your dog's nails at home feels daunting mainly because you're afraid of making them bleed, but with a good tool, good light and small cuts it's a five-minute job. If you can hear their nails clicking on the floor as they walk around the house, they're already too long.

Nails that are too long force a dog to put their paw down badly: they splay the toes, strain the joints and make the dog slip, which really shows in older dogs. Here we explain how to see how far to cut, even on black nails, what to do if a nail bleeds, how often to repeat it and how to get your dog to tolerate it.

When to trim them

With your dog standing on a smooth surface, their nails shouldn't touch the floor. If you can hear them as they walk or their toes are being pushed sideways, the nails are too long. How often depends on wear: a dog that walks a lot on pavement may rarely need it; one that lives between the lawn and the house, or a small older dog, every 3-4 weeks.

The dewclaw, the toe on the inner side of the leg, higher up, doesn't touch the ground and doesn't wear down. It grows in a curve and can end up growing into the skin. Always check it. Some breeds, such as the Great Pyrenees, have double dewclaws on their hind legs.

If the nails are very long, the quick inside has grown too, and you can't shorten them all at once. Trim a little every 1-2 weeks: the quick will gradually recede.

How far to cut: light nails and black nails

Inside each nail there's a living part, the quick, with a blood vessel and a nerve. If you cut it, it bleeds and hurts.

Type of nail	How you see the limit	How much to cut
Light or white	You can see the pink area inside the nail	Up to about 2 mm (1/16 in) before the pink
Black	You can't see it from outside: look at the cut surface	Slices of 1-2 mm (about 1/16 in) until you see the signal to stop

On black nails, look at the cut surface after each slice. As long as it looks whitish and dry, you can keep going. When a lighter ring appears with a dark, moist dot in the center, stop: that dot is the start of the quick.

Cut following the natural angle of the nail, so the tip ends up roughly parallel to the floor, not straight across toward the pad.

Which tool to choose

Tool	Best for	Keep in mind
Plier- or scissor-style nail clippers	All dogs, especially medium and large	Gives you a lot of control; make sure they're sharp
Guillotine nail clippers	Small and medium nails	If they're not sharp, they crush the nail instead of cutting it
Electric nail grinder for dogs	Black nails and dogs that won't tolerate clipping	Your dog needs to get used to the noise; tie back long fur so it doesn't get caught, and don't hold it on a nail for more than 1-2 seconds at a time because it heats up

Human nail clippers crush and splinter the nails of a medium or large dog. For a very small puppy, cat nail clippers can work.

If a nail bleeds: what to do

It happens to everyone at some point. Stay calm, because your dog picks up on how you react.

• Apply styptic powder to the tip of the nail and press for 1-2 minutes. You'll find it at pet stores and pharmacies.
• If you don't have any, press on cornstarch or flour, or hold a gauze pad on it for five minutes without lifting it to look.
• Keep your dog from running or jumping for about 15-20 minutes so it doesn't start bleeding again.
• Don't use alcohol or hydrogen peroxide: they sting and don't help stop the bleeding.

See the vet if it hasn't stopped bleeding after 10-15 minutes, or if a nail has broken and is hanging off or has the quick exposed: it's very painful and usually needs to be removed under sedation.

How to get your dog to let you do it

• Get them used to having their paws touched at calm moments, on the couch, with a treat.
• Show them the clippers, let them sniff and reward them, without cutting anything. Then touch their nails with the clippers, still without cutting.
• One nail a day is perfectly fine. You don't have to do them all at once.
• A lick mat spread with plain yogurt or pumpkin keeps them busy while you trim.
• Ask someone to help you hold and reward them.

If your dog is very scared, growls or tries to bite, don't force it: every bad experience makes things worse. A basket muzzle they're already used to, a dog groomer or your vet are better options, and some dogs need light sedation.

Warning signs in the nails

• Nails that grow very long, thick and curved for no obvious reason: this is a common sign of leishmaniasis, a parasitic disease that is very widespread in Spain and the rest of southern Europe. It's rare in the US and UK, but tell your vet if your dog has lived in or traveled to the Mediterranean.
• Nails that break, come loose or become misshapen on several toes at once: it may be an autoimmune nail disease.
• A swollen, hot toe with pus, or limping.
• A dewclaw growing into the skin: only trim it if you can clearly see what you're doing; if the wound is infected, go to the vet.

What you need

• Sharp plier-style or guillotine dog nail clippers
• A nail file or an electric nail grinder for dogs
• Styptic powder (or cornstarch)
• Small treats
• Good light or a flashlight
• A towel, to wrap a small dog in

Step by step

1. Position your dog

   Lying on their side or sitting, and small dogs on your lap. Good light, and everything within reach before you start.

2. Hold the paw gently

   Hold the paw firmly but without squeezing, and press gently on the toe pad so the nail extends. Move the fur out of the way.

3. Find the limit

   On light nails, look for the pink area. On black nails, get ready to cut thin slices and check the cut surface each time.

4. Cut a little, decisively

   One quick cut of 1-2 mm (about 1/16 in), following the angle of the nail. Slow cuts squeeze the nail and are more uncomfortable.

5. Check the dewclaw

   It's on the inner side of the leg, higher up. Trim it like the other nails; it's easy to forget.

6. File and reward

   File the edges so they don't snag, and reward your dog after each paw, not just at the end.

Frequently asked questions

How often should I trim my dog's nails?

Usually every 3-6 weeks, but it depends on how much they wear down. The rule of thumb is simple: with your dog standing, the nails shouldn't touch the floor or click as they walk. Dogs that rarely walk on pavement, small dogs and older dogs usually need it more often. Check the dewclaw too, because it never wears down.

What do I do if I cut my dog's nail too short and it bleeds?

Press styptic powder onto the tip of the nail for one or two minutes; if you don't have any, use cornstarch or press a gauze pad on it for five minutes without lifting it. Keep your dog from running for a while. It usually stops quickly. If it's still bleeding after 10-15 minutes or the nail has broken and is hanging off, take your dog to the vet.

How do I know how far to cut black dog nails?

Cut thin slices of 1-2 mm (about 1/16 in) and look at the cut surface each time. As long as it's whitish and dry, you can keep going. When a lighter ring appears with a dark, moist dot in the center, stop: you're very close to the quick. If in doubt, an electric grinder lets you go more slowly.

Is it better to clip or grind a dog's nails?

Both are good options. Clippers are faster and quieter; a grinder lets you shorten the nail little by little, leaves it rounded and makes it easier to avoid the quick, especially on black nails. Many dogs tolerate one better than the other. What matters is that the tool is in good condition and you go slowly.
