What to eat if a dog drools?

It is better for a dog to eat liquid food if it drools. Dogs drooling are most likely caused by oral diseases. If there is discomfort in the dog's mouth, it will cause pain to the dog, so the dog will open its mouth to avoid or relieve the pain. It is best to feed your dog light liquid food to avoid worsening of pain caused by chewing. Supplement your dog with appropriate vitamins, and take your dog to the hospital for examination and treatment if necessary.
