Now you can cut your dog's nails safely without worrying about cutting them too short. I bought one of these clippers because twice in my life I've cut the dog's nails too short. It's awful. It takes forever them to stop bleeding and I felt terrible that I did something to hurt them. I'd gotten where I was going way to long and cutting them way too long to avoid any danger. With this clipper you get a red light if you're going to cut into where there's blood. We've only got these in Grand Forks for now to see how they sell. They are a bit expensive.
