The dog at home is diagnosed with enteritis. We can treat the dog as follows: 1. First, fast the dog from food and water to reduce the burden on the gastrointestinal tract. 2. Purchase pet anti-inflammatory drugs and pediatric anti-inflammatory drugs, and compare them according to the dog’s weight. The dosage of the medicine should be fed to the dog. 3. The dog will be significantly improved in 1-2 days after treatment. At this time, the medicine can be stopped and some light and easy-to-digest food can be fed to help the dog recover its physical strength.
