Ask a Dog Vet and Get Answers to Your Dog Health Questions
Thank you for your question. My name is***** I have been a small animal veterinarian for 14 years and I'd like to help with your question. The symptoms that your dog is having definitely sounds like it could be a parvo virus infection.... it could be other things too. To prevent parvo your puppy should have had a series of 3-4 vaccines starting at about 7 weeks and ending at about 4 months. Did you do this series? If not I would be really worried about Parvo. This is a very serious infection and I would really recommend taking her to a veterinarian. If you absolutely can't then she is likely to continue to get worse. The best thing that you can do is focus on keeping her hydrated. I wouldn't worry about getting her to eat right away, just focus on getting her to drink small amount of diluted chicken broth every hour so she doesn't get dehydrated. If she won't drink or if she can't hold down liquids then she really needs to see a veterinarian.
Other things... such a an intestinal blockage can also cause vomiting and lethargy... but an X-ray would need to be taken to detect this.
I hope that helps, but if you have more more questions please let me know.
