Cutting off a dog's tail depends on the breed of the dog. If it is forcibly cut off, it will have a great impact on the dog's psychology and physiology, and may even cause the dog's death. At present, Doberman pinschers and Teddy dogs are the more common tail-docked dogs in daily life. When docking their tails, they need to go to a professional pet hospital for surgery to avoid life-threatening injuries to the dogs.
