I have a German Shepherd dog and I purchased this Dremel Minimite to grind his nails. Works very well once the dog was used to it; he didn't want to get near it at first. I use the fine sanding band on high speed on the nails as I think the coarse bands would be too much. I've also found many other uses for the Dremel around the house so it's definitely handy. If you have a specific need, I'd recommend purchasing and I'm sure you'll find other uses also. The rechargeable battery is great, which is why I purchased this over the products marketed for grinding pets' nails. For a few bucks more, The Minimite is worth not having to replace batteries that you have to purchase separately.
