Normally, the dog's hair plays a role in keeping warm and isolating the outside world. When the hair is just shaved, the dog will feel uncomfortable with the outside temperature. This is normal. If the dog at home is healthy and has no skin diseases, it is not recommended to shave. If the dog is a large long-haired dog, it can be shaved in summer. This can help the dog dissipate heat and help it withstand the summer temperature.
