Shave the dog at home. Maybe the dog is not cooperative and needs the help of others. You can choose to let the dog lie on the ground or on your legs (if it is a puppy), with the stomach facing up, holding the dog's two forelimbs with one hand and letting others hold the other two hind legs. Generally, it can be scraped from the navel to the inside of two thighs. If you are a dog who often climbs stairs, be careful to catch cold. Better not shave now.
