Vomiting after eating.

Dr. Marie replied:

Sorry to hear that Rocky is not feeling well. There are many things that can cause vomiting and diarrhea. It will be hard to say over the internet what the cause is but I'll give you a few of my thoughts:

When a young dog vomits after eating (but still wants to eat) I get concerned about him having a foreign object (such as a toy or cloth) in his stomach. If this were the case he may need surgery.

Some parasites can cause vomiting and diarrhea.

A virus such as parvo virus can cause this but shouldn't be going on for 20 days.

A kidney problem (i.e. after exposure to a toxin or an infectious agent called leptospirosis) could cause these symptoms.

Some dogs can have vomiting and diarrhea with a food intolerance or allergy but this is not actually very common.

There are many other conditions that could cause these symptoms as well.

If your dog has been unwell for 3 weeks now he really does need to see a vet. Bring a stool sample with you and they will do some lab tests for parasites. They may also want to do some bloodwork.

I hope he does ok!

Dr. Marie.
