I have used and liked:

Nail Filing Puzzle

Most dogs like it right away! You can add weight to prevent moving around too much

Nail Filing with Treat Box

Either if they like scratching or they know to scratch this shape helps to take care of the 4 nails. Comes in different size

Neil Grinder

Diamond drum so it doesn’t get warm, rechargeable, low noise and has 2 speeds

Finger Toothbrush

A great option to get them use to you managing their mouths, cleaning their teeth and massaging their gums
