What is the quick in a dog's nail?

A dog's nail has two parts. The AKC describes a hard outer shell and the living pink quick inside it, running through the core and carrying blood to the nail. VCA adds that the quick contains nerves as well as blood vessels. That is the whole story of a bad trim: the shell can be cut, filed or ground without the dog feeling much, but the quick is alive, so a cut into it hurts and bleeds, often more than you would expect from something so small.

Seeing it depends on the color of the nail. On a pale or white nail the quick shows through as a pink core, and VCA suggests stopping about 2 to 3 millimeters short of it. On a black nail it is invisible from outside, so the cut surface has to be read instead: the AKC tells owners to watch for a chalky white ring, and the ASPCA describes the circle that appears as you near the quick as the signal to stop. VCA suggests taking only 1 to 2 millimeters at a time on dark nails.

The fix for a long quick is patience. The AKC says plainly that regular nail trimming will cause the quick to recede from the end, and most dogs need trims every three to four weeks, some more often. Each trim takes only what is safely clear of the quick, the living tissue draws back a little, and the next trim can take a little more. No single sitting brings a long-neglected nail back to an ideal length without hurting the dog.

Plan it as a series rather than an event. Tell the groomer the nails have been long for a while, expect the first trim to look conservative, and book the next ones close together. Between trims, keep handling the feet at home with treats, because VCA notes that the earlier a dog is comfortable with nail trims, the easier grooming becomes. Once the nails sit just clear of the floor, hold that rhythm and the quick stays short.

Nail clipping at Dogtown is $16, added to a bath, from $55 by weight, or to a full service, from $75, and grooming needs no evaluation. Whether the groomer clips, grinds or does both is confirmed with you at check-in, so say if your dog has had a quick cut before or reacts badly to one tool. A dog that needs slower, more careful handling carries the $20 behavior or handling surcharge, and you hear about it before the trim starts.

Cape Ann winters are hard on nails. Soft sand on the off-season beach days, at Wingaersheek on odd-numbered days from October 1 to April 30 at the time of writing, and soft snow file almost nothing off, and the AKC notes that long nails reduce traction, which matters on icy sidewalks. Rebook at pick-up for $5 off, three to four weeks out. Daycare dogs can have nails done during their day, and the Pup Van runs at $10 each way in Rockport, Gloucester, Essex and Manchester-by-the-Sea.
