Short answer
Most dogs need a nail trim about once a month, and nails that touch the ground or click on hard floors are too long. Clippers are quick. VCA says grinders carry less risk of damaging the quick, but the spinning file can catch long hair, burn skin if it slips and make irritating dust. Whichever you use, take a little at a time, keep styptic powder nearby, and stop if your pet is stressed.
How often, and how much
VCA says most dogs need their nails trimmed about once a month. Dogs walked often on pavement may go longer, and inactive dogs may need trims as often as every three weeks. Nails that touch the ground or click on hard floors are too long.[1] AKC's breed pages vary more, from every two weeks or so for Bulldogs to weekly for Rottweilers,[2][3] so check the nails rather than the calendar.
Inside each nail is the quick, the blood vessels and nerves that supply it.[4] Cut into it and the nail bleeds and hurts, though VCA's behavior authors note the pain is usually brief.[5] On light nails, VCA advises cutting about 2-3 mm away from the visible quick. On dark nails, trim just the tip, then take 1-2 mm at a time.[1] Washington State University adds a stop sign: when a gray-to-pink oval appears on the cut surface, the next cut would reach the quick.[4] Step by step: how to trim dog nails, including dark and black nails.
Clipper or grinder?
| Nail clipper | Nail grinder | |
|---|---|---|
| How it works | Cuts the nail in one squeeze | A spinning file wears the nail down |
| Strengths | Fast, with no motor noise or dust | Smooth nail end and less risk of damaging the quick, per VCA |
| Watch for | Taking too much at once, especially on dark nails | Hair caught in the file, skin burns if it slips, dust, and heat if held on too long |
VCA describes the two main clipper styles, guillotine and scissor, as both effective, with owners developing preferences.[1] Its behavior authors advise avoiding guillotine clippers with only one sharp blade, which often crush the nail. Washington State University calls the guillotine type the easiest to use in dogs and says the scissors type is often used for dewclaws.[5][4]
For grinders, VCA warns that the file can tangle in long hair, can cause a severe skin burn if it slips, and makes irritating dust, so grinding outdoors may be best.[1] Its behavior authors suggest grinding for just 1-2 seconds at a time, or the nail heats up.[5] Full comparison: nail grinder vs nail clipper.
Dewclaws, overgrown nails and cats
Dewclaws do not touch the ground, so walking does not wear them down. VCA says they often become overgrown and can curve into the paw pad, so they must be trimmed. In dogs that miss regular trims, the quick may have grown out almost to the end of the nail.[1]
For cats, Cornell advises gently squeezing the paw to extend the claw and trimming at an angle that removes the hook at the end, avoiding the quick, and suggests asking your veterinarian for a lesson.[6] ASPCA suggests a trim every ten days to two weeks.[7]
If a nail bleeds, or your pet is scared
Keep styptic powder within reach before you start. If you cut the quick, VCA says to apply a small amount to the end of the nail, or flour or cornstarch if you have none. Washington State University notes that without styptic powder, bleeding may take about 5 minutes to stop.[1][4] More in what to do if you cut the quick.
VCA lists the stress signs to watch for: moving or leaning away, looking away, yawning, shaking off, ears folded back and a tucked tail. Trembling, excessive drooling, panting, growling or snapping signal more serious distress. Pause when you see them. Dogs that already fear nail care often need personalized professional help, and a veterinarian can use a light sedative to trim nails without a struggle.[8] For a dog that hates trims, VCA suggests not aiming to do every nail in one sitting.[1]
Choosing your tools
The whole kit is a clipper sized for your dog's nails, a grinder if your dog tolerates one, styptic powder and good light. For a rechargeable tool, use the charger it came with, as Health Canada advises.[9] Our paw and nail trimming tools shortlist explains why we picked the grinder below. The scissor-style clipper adds a small LED light; we could not verify whether it helps you see the quick on a dark nail.

Common questions
How do I find the quick in a black dog nail?
You usually can't see it from outside, so use the cut surface instead. WSU's cue is to stop when a gray-to-pink oval appears on the cut end, because the next cut reaches the quick. More in How to trim black dog nails
How much should I cut off a black nail at a time?
VCA says to trim just the very tip first, then make a series of small clips that remove 1-2 mm each. More in How to trim black dog nails
Is a nail grinder better for black nails?
VCA says grinding carries less risk of damaging the quick, but the spinning file can catch long hair, burn skin if it slips and make irritating dust. VCA's behavior authors recommend touches of only 1-2 seconds so the nail does not heat up. More in How to trim black dog nails
Does an LED nail clipper show the quick in black nails?
We have seen no evidence that it does. Treat the light as a way to see the nail and the cut surface clearly, and still take small slices on dark nails. More in How to trim black dog nails
My dog has both black and white nails. Should I trim them differently?
Yes, nail by nail. On light nails VCA advises cutting about 2-3 mm from the visible quick; on dark nails, trim the tip and then take 1-2 mm at a time. More in How to trim black dog nails
How often should I trim my dog's nails?

How close to the quick can I cut my dog's nails?

Should I use a guillotine or scissor nail clipper?
VCA says both styles work and owners develop preferences, while WSU calls the guillotine type the easiest to use on dogs and notes scissors-type clippers are often used for dewclaws.

Questions
How often should I trim my dog's nails?
VCA says about once a month for most dogs, sooner for inactive dogs and later for dogs that walk a lot on pavement. If the nails touch the ground or click on hard floors, they are too long.[1]
Is a nail grinder safer than clippers?
It trades one risk for others. VCA says grinding carries less risk of damaging the quick, but the file can catch long hair, burn skin if it slips and make irritating dust. Grind for 1-2 seconds at a time so the nail does not heat up.[1][5]
How close to the quick can I cut?
VCA advises staying about 2-3 mm from a visible quick. Washington State University says not to cut within 2 mm of it and to stop when a gray-to-pink oval appears on the cut surface.[1][4]
What should I do if I cut the quick?
Stay calm and apply a small amount of styptic powder to the end of the nail; VCA says flour or cornstarch can stand in. Without styptic powder, bleeding may take about 5 minutes to stop, WSU notes. Call your veterinarian if you are worried.[1][4]
Do I have to trim all the nails in one session?
No. For a dog that dislikes nail trims, VCA suggests not aiming to clip every nail in one sitting, and building up from touching the feet to one nail per session over several weeks.[1]
