Why do my dog's nails click on the floor?

A nail that has grown past the pad hits the floor before the paw fully lands, producing a sharp tap with each step. On carpet the sound is muffled, which is why many owners only notice the problem once their dog walks across a kitchen or hallway floor.

Persistent clicking usually means the nails are pushing the toe joint slightly out of its normal position every time the paw lands, which over months can change how a dog distributes weight across its foot. A dog whose nails click constantly is a good candidate for trims every 2 to 3 weeks rather than the standard 4.

A single trim rarely silences the clicking completely if the quick has grown long along with the nail, since you can only take off a small amount at first. Two or three trims spaced 2 weeks apart, each removing a small slice, usually gets the nail back to a length where it no longer touches the floor.

Clicking is far more obvious on hardwood, tile, or laminate than on carpet or rugs, which can mean a dog living mostly on soft flooring goes longer before an owner notices overgrown nails simply because the usual warning sound is muted. Doing a periodic hands on check, rather than relying on hearing alone, catches this in homes with a lot of carpeted floor space.

A sudden change from quiet to noticeably clicking within just a week or two, rather than a gradual return of the sound over the usual month, can also be a clue that your dog's activity level has dropped recently, since less walking directly means less natural wear.
