We can push the dog's hair like this: 1. Prepare a pet shaver or hair clipper, rinse the dog's hair well, and comb it smoothly. 2. Someone else needs to control the dog to avoid injury during the hair pushing process. Then use the hair pushing tool to operate counterclockwise. 3. First shave the hair on the dog's back, and then trim the hair on the belly, limbs, tail, and the dog's head and ears. Do not use shaving tools, but use scissors.
