I have an Andis nail grinder for the dogs...sort of like a Dremel, but not as much power so it's not as noisy. I've used it for years, and the dogs will tolerate it way better than clippers.
Found this on Amazon the other day, which will solve the only problem/complaint I had with the grinder...that the drum was a bit too big for the dogs' tiny nails. PROBLEM SOLVED!!
It's an accessory pack for my grinder. It has a replacement regular head, but also a much smaller one! And that pink thing on the left is a smoother. I won't use it much if at all, but still. Anyway, I"m eager to try it. I imagine it will make the whole process that much easier, especially for Tango and his dewclaws! They're the worst, but all of his nails curve far more than Jazz's do, so the smaller head will be a huge help.
I'll let you know how it goes!
