Switching from cutting our dogs' nails to using a dog nail grinder was a game-changer for all of us. So much less drama. No more accidental injuries from cutting nails too short. Best of all, the dogs no longer look at me with murder in their eyes when it's time to do their nails -- which I grind down weekly. Yes, really. I've gone through a bunch of different grinders since Clover was a puppy, including an entry-level one that went through untold numbers of D batteries and replacement heads. I've had other (nicer) ones that died after a year or so. I'm now using a new / different one, so here is our review of Lucky Tails Nail Grinder.
