Definitely not! If you feel the material it's made out of, it's like a rubber, but it doesn't pull on the dog's hair. My dog always found it very relaxing, and would often fall asleep while we used this brush. Nothing to fear!
This is the curry comb of the dog world, so it doesn't. All it does is loosen up and remove the fur that's already loose. It doesn't catch or snag or pull on the hair that isn't already loose, so it's much more comfortable and enjoyable for the dog.
