Scratch to file.
The top is sandpaper. Each time your dog scratches across it, the tips of the nails are filed down a little.
ClipProof™ Nail Board
Free shipping over $70, flat $7.99 under that. 45-day returns. Delivery details
A round board with a sandpaper top, a solid wood rim and a treat cup. Your dog scratches across the top to reach the treat and files the tips of their nails as they go. Cats can use it too.
Use it between nail trims, not instead of them.
The top is sandpaper. Each time your dog scratches across it, the tips of the nails are filed down a little.
Drop a treat in the wooden cup, guide a paw across the board, then reward. A few minutes a day is plenty.
Put it on the floor where your cat already likes to scratch.
Long nails tap and slide on hard floors. Short nails give paws a better grip on smooth floors.
It helps between trims. Plan on the odd clip as well, and dewclaws never touch the board.
Treat in the cup, one paw guided across the sandpaper, reward straight away. Keep sessions short and stop while they are still keen.
