Veterinary questions? Ask a Vet for Answers ASAP
Thank you for your question. My name is Dr. Stacy. I have been a small animal veterinarian for 16 years and I would like to help. Can you tell me when your puppy received her most recent vaccine?
At 4 months of age your puppy is very susceptible to parvo virus. Any immunity that she received from her mother has worn off and unless she has been fully vaccinated against parvo she is susceptible. If more than 4 weeks has passed since her last vaccine then she is susceptible. She is just over that 4 week mark. The symptoms of parvo include lethargy, vomting and bloody diarrhea. I suspect this is what is going on.
Parvo is a serious and potentially life threatening virus that is ideally treated with IV fluids and medications. Can you get her to a veterinarian ASAP for testing and treatment? If not, then the best thing you can do for her at home is focus on keeping her hydrated.
Other potential causes of lethargy and bloody stool include some parasites (although those are more of a problem around 2 months rather than 4 months) or toxins. You would need testing to know for sure.
okay... until then just focus on keeping her drinking. You can dilute pedilyte half and half with water and see if shell drink it. If not, then dilute chicken broth is fine. I wouldn't worry about food unless she wants a little bit of something easy to digest like chicken meat. That would be fine.
If she is drinking and not vomiting then tomorrow should be fine for the vet, but if she is weak or has severe vomiting then try to get her in sooner.
I hope that helps, but if you have more questions please let me know.
