I'm sure a lot of bulldozing officers feel the same way when they take dogs to a pet hospital -- tired, like they're empty! In fact, dogs are like kids who go to the hospital and they're afraid to cry, and it's just the way they feel, and in his eyes, a couple of strangers are holding instruments and pressing them on a counter. So how can they not be afraid?

One.
Put a desk or desk at home and pretend to be an instrument. And ask your friends to pretend to be a pet doctor or a hairdresser.
Two.
Let your friends in the house and then take the dog slowly and gently to the table and give it some time to stay high. Remember, desktops can't be too smooth, slipping increases the fear of dogs. Also, if it's winter, it's colder, it's better to bring a little mat to the dog to reduce his discomfort.
Three.
Friends come around, pretend to check. The master should keep touching the dog's body at this point, so that the dog can feel safe and be rewarded for some food.
Four.
Practice more, so that the dog can adapt to the table until it's calm, so that you can rub its ears, eyes, mouth, claws and hips. If the dog expresses fear (e.g., licking the lips, clawing, mouthing or breathing), you have to help calm it down; if the dog is able to be examined quietly by a friend, your friend can reward it with food.
