The two-month-old puppy retches and does not vomit.

The two-month-old puppy retches and does not vomit. The possible reasons are as follows:
1. Caused by parasitic infection, the owner did not treat the dog on time. Internal and external deworming treatment will cause symptoms of parasitic infection. Dogs should be dewormed in time.
2. Caused by infectious diseases, such as canine distemper, symptoms such as coughing and retching may appear in the early stages. It is recommended to send the dog to a pet hospital for examination and treatment in time.
3. Foreign objects stuck in the throat may be caused by the owner feeding food containing bones, or the dog accidentally eating the throat and causing the throat stuck. It is recommended to seek help from a pet hospital to avoid blindly inducing vomiting and causing secondary injuries.
