A friend of mine tells me that the Petipaws (grinder) works, but leaves snags on the nails. Another friend tells me that the Petipaws is better than clippers, and that it does leave snags if you aren’t very careful.
Since I don’t have a dog anymore, I haven’t tried it myself, so I’m handing out hearsay.
All the cats here have been declawed, the dogs are outside dogs so, don’t need one of those things.
