I have a Chihuahua-Dachshund mix dog, and this tool cuts his nails perfectly. I love that it has a safety feature, so I don’t cut too much off his nails.
This claw scissors was too blunt right from the start. It barely cuts my dog's black, tough claws. You can only use it with a lot of force, but then it crushes and splinters the claws rather than cutting them, which is very uncomfortable for dogs. Not recommended.
