Harry was rescued off the streets, he’d never been groomed before. It took a couple of days to introduce him to the glove. Once he was comfortable with the glove, he asks to be groomed. Let them take their time, do not force a grooming product on your cat or dog. Any professional groomer will give you the same advice.
Make sure you visit only a professional certified groomer. Please do not Google “dog groomer near me” and make your choice. Inexperienced groomers can harm your cat or dog. In extreme cases pets have died when handled aggressively by inexperienced groomers.
