Long nails are why some dogs slip — and it is free to fix

Every other page in this section sells you something. This one does not, because for a meaningful number of dogs slipping on hard floors the problem is not the floor, the paw pads or the lack of socks. It is that the nails are too long, and the fix is a nail trim.

It also happens to be a problem that gets worse precisely as a dog gets older, for a reason that is easy to miss: nails wear down through walking on abrasive surfaces. A senior dog who used to do three miles a day on pavement and now does two gentle laps of the garden is simply not wearing them down any more. The trimming schedule that worked for years quietly stops being enough.

Why nail length changes footing

A dog's grip on a hard floor comes from the paw pads — the textured, slightly tacky surfaces on the underside of the foot. The nails are not the gripping surface indoors; on soft ground they dig in usefully, but on hardwood or tile they are hard keratin against a hard sealed surface, and they slide.

When nails get long enough to contact the floor while the dog is standing normally, two things follow. The nail takes contact that should be going through the pad, reducing the pad area actually pressing down. And the toe is pushed back and up, which alters how the foot is loaded and, over time, how the dog stands.

For a young dog this is a minor inefficiency. For an arthritic senior with reduced strength, already-poor footing and no margin for a scramble, it stacks on top of everything else — and it is the one part of the stack you can remove this week for nothing.

The test, which takes four seconds

Stand your dog on a hard floor in their normal posture and listen, then look.

• Listen. Audible clicking as your dog walks across a hard floor means the nails are contacting it. On a standing dog nails should not touch the ground.
• Look from the side. With the dog standing square, the nails should clear the floor. If they are touching, or bending, they are too long.
• Check the dewclaws. Higher up the inside of the leg, they never contact the ground and therefore never wear at all. They are the ones that curl round into the pad, which is painful and easy to miss under fur.

The clicking test is the one to remember, because you can run it without doing anything. If you can hear your dog crossing the kitchen, that is the sound of nails on tile.

Getting them shorter, on a dog that hates it

The AKC's guidance on trimming dog nails is the place to start for technique, and we are not going to duplicate it here. If the open question is which tool — a rotary grinder or clippers, and which of either suits arthritic hands and a dark nail — our nail grinder and clipper comparison works that out. What we will add are the senior-specific parts:

• Standing on a slippery surface makes it worse. An arthritic dog being asked to balance on three legs on tile while you handle the fourth is entitled to object. Do it on a rug or a non-slip mat, and let the dog lie down if that is easier for them.
• Holding a leg up is a joint position. Extending a stiff hip or elbow to get at a foot hurts. Work with the leg low and close to the dog's body rather than pulled out.
• A long overdue nail cannot be fixed in one go. The quick — the blood vessel and nerve inside the nail — grows forward as the nail grows. Frequent small trimmings encourage it to recede over weeks. This is a slow project, not a single appointment.
• Split it across days. Two feet today, two tomorrow. A senior dog's tolerance for being handled is shorter than it used to be, and forcing it teaches them to dread the clippers.

If your dog will not tolerate it, a vet nurse or groomer doing it every few weeks is money well spent — and considerably cheaper than the traction gear you would otherwise buy to compensate.

Then do the rest of the footing

Nails are the free part, not the whole answer. A dog with correct nails on polished hardwood is still a dog on polished hardwood. Once the nails are right, the rest of the fix is:

• Fur between the pads. The other free fix, and it matters as much as nails. Hair growing over the pads lifts the gripping surface off the floor — trim it back level with the pad.
• Grip on the paw. Socks, toe grips or wax, depending on the dog — our grips versus socks comparison is the place to choose.
• Grip on the floor. Runners along the routes the dog actually uses. Our floor setup guide covers the layout.

Interestingly, nail length is also the thing that decides whether toe grips are a sensible option at all — they fit onto the nail, so they need a nail of reasonable length and condition to sit on. Our toe grips page covers the fitting.

The order to do this in

1. Listen for clicking. If you hear it, the nails are long.
2. Trim, or book someone to. Split it across days for a stiff dog.
3. Trim the fur between the pads level with the pad.
4. Re-test on the kitchen floor a week later.
5. Only then decide what grip product, if any, you still need.
