The reasons why the puppy keeps drooling:

1. The drooling of the puppy may be caused by the esophageal blockage caused by the dog eating too fast, which then causes vomiting and drooling.

2. The puppy accidentally eats irritating items such as peppers and disinfectant, which stimulates the secretion of saliva in the mouth and is accompanied by vomiting.

3. Dogs suffering from oral diseases, such as periodontitis, oral ulcers, etc., will also have symptoms of drooling after eating.

Solutions to a puppy that keeps drooling:
1. If it is caused by esophageal obstruction, the foreign body should be removed and the dog should be given a balanced diet.

2. If it is caused by accidentally eating irritating items, it is recommended to rinse the mouth with saline and provide enough drinking water.

3. If it is caused by oral disease, the dog should be treated with anti-inflammatory medicine in time, and the dog should be taken to the hospital for treatment in time.
