Nail trimming is the single most postponed part of pet care, and it is the one with the clearest physical consequences. When nails are too long they touch down before the pad does, which quietly changes your dog's posture with every step they take.
What to look and listen for
Most of these are easy to check at home in under a minute:
- You can hear clicking on hard floors when your dog walks
- Nails touch the ground while your dog is standing still
- Your dog slips on tile, laminate, or hardwood they used to handle fine
- The nails curve rather than pointing straight down
- Nails catch on carpet, blankets, or your clothing
- Your dog has started licking or chewing at their feet
Why it matters more than it looks
When a nail hits the floor first, it pushes the toe backward on every step. Over months and years, that alters the angle of the foot, the wrist, and eventually the hips. In older dogs it can meaningfully worsen the discomfort of existing arthritis, and it is a common hidden reason a senior dog becomes reluctant on slippery floors.
There is an immediate risk too. Overgrown nails catch and tear, which is painful and bleeds considerably. In extreme cases a curved nail can grow all the way around and into the pad itself, which requires veterinary attention.
The quick that everyone worries about
Inside every nail is the quick — the blood vessel and nerve. Cutting it hurts and bleeds, which is exactly why so many owners feel nervous doing this at home. It is a reasonable worry.
The useful thing to know is that the quick recedes as the nail shortens. If nails are very overgrown, the fix is not one dramatic trim but a series of small ones every couple of weeks, letting the quick withdraw a little each time. Rushing it is what causes the injury people fear.
How often, realistically
Most dogs need a trim every three to four weeks. Dogs who walk regularly on pavement wear their nails down naturally and may stretch further; dogs who spend most of their time on grass and carpet almost always need trims more often than their owners expect.
Dewclaws deserve a specific mention because they touch nothing at all and therefore never wear down. They are the nails most likely to curl into the leg, and they are the ones most commonly missed at home.
