I took my Coton de Tulear here for a grooming. Cotons have very thick, cotton like long fur. I had meticulously combed out EVERY matt to make sure she wouldn't get shaved. I specifically mentioned how thick their fur is and that she had NO matts. I came back about 15 minutes later and the woman was SHAVING my dog. My dog literally had four inch fur in some sections and zero fur in sections. The woman even nicked the skin in areas where she was bleeding. Needless to say I grabbed my dog and ran (after complaining to the manager). If you have a tricky dog grooming, NEVER take your dog to Petco grooming. They have no idea what they're doing.
