How short should I cut my dog's nails?

A well trimmed nail sits roughly level with the bottom of the paw pad when your dog stands on a hard floor, no longer touching the ground and no longer clicking. Going shorter than this risks the quick; going much longer defeats the purpose of trimming at all.

On white or clear nails, hold the paw up to natural light and you can usually see a pink line running through the center; trim to about 2 mm short of where that line ends. On black nails, take off 1 mm at a time and check the cut surface after each slice; a chalky white ring appearing means you are getting close, and a pink or grey dot in the middle means stop immediately.

The quick actually grows longer the more the nail is left untrimmed, which is why very overgrown nails cannot be brought to ideal length in a single session. Regular trims every 2 to 3 weeks gradually encourage the quick to recede, so a nail that once needed a cautious 1 mm slice can eventually be trimmed further back.

Many professional groomers work toward a standard where the nail sits roughly perpendicular to the ground when a dog is standing, neither curving forward past the paw nor cut so short it looks flush with the pad. Asking a groomer to show you the finished length on your specific dog during one visit, rather than relying on a general description, gives you a concrete visual target for future home trims.

A useful mental marker for many dogs is trimming until the nail is roughly level with the surrounding fur when viewed from above, though this varies with paw shape, so combining this visual check with the floor touch test gives a more reliable overall read.
