Personally I think dying dogs is silly and time consuming. That said, those dog’s owners obviously love them a lot and those dogs are way better off then dogs without homes or whose owners neglect them. I figure if the dog really hates it he/she will let the groomer know (they tend to make their point with teeth) and the groomer won’t do it. I wouldn’t do it to my dog but I wouldn’t condemn someone to doing it to their dog if 1) the dog doesn’t mind and 2) the dye doesn’t hurt the dog.
