The body temperature of dogs is constant. The normal body temperature of adult dogs is 37.5℃~38.5℃, and the body temperature of young dogs is 38.5℃~39℃. If the dog’s body temperature exceeds 39℃, it means it has a fever. If the dog has a fever, it will also show symptoms such as dry nose, hot belly and ears, loss of appetite, increased eye secretions, etc. If the situation is serious, you need to take the dog to the pet hospital for examination and treatment in time to avoid delaying the condition.
