The dog’s nose is wet but a little hot. It may be because the weather is hot or he has just finished exercising. The dog needs to dissipate heat through the nose, so the nose will become wet and hot. If the dog’s nose is a little hot under normal circumstances, , then it may be caused by colds, internal parasites, viral infections, etc. You need to take the dog to the pet hospital to check the cause and carry out targeted treatment.
