If your dog appears in this state at home, you must first check whether the dog has been vaccinated recently. If it appears after the vaccination, it may be caused by the vaccine in the body. It will get better after 5-6 days. If not, it should be caused by inflammation, virus infection, or disease in the dog's body. It is recommended that the breeder send the dog to the pet hospital for treatment in time to prevent the dog from becoming seriously ill and leading to death.
