A hairdresser. We’re dealing with animals and their whole bodies, not just hair on the head. They wiggle, they bite, they pee/poop, etc. many hairstylists try it thinking if they can do it on humans, they easily can groom a dog. Not true as the procedures and way you cut the fur on a dog is much different. I don’t count it with “hair and nails” because it’s animals instead of people.
