Query: bleeding lab

The furminator cut my lab. I would not use it again. I combed her with it and left for the day, when I came home later, blood was on the walls and on her fur. I would have mailed it back, but I threw out the box. I did not use it inappropriately, going over a section again and again. It got the fur off, but Ginger was nervous and wondered where the blood came from and kept licking herself.
