My dog won't eat his food and vomits. Is it parvo or something else?

Updated on September 23rd, 2025

Pet's info: Dog | American English Coonhound | Male | 7 years and 2 months old | 72 lbs

Hi I have a 7 year old coonhound who always ate anything but recently he hasn't been eating his food, just picking at it and then heaving and vomiting it up. He won't do this with treats though. I'm worried he may have parvo? Or be dying? He seems fine. Just won't eat much and vomit his food up.

Parvo virus can occur in adult dogs but often is more of a worry in puppies. Rye could have some other infection or a GI foreign body or perforation if he chews or eats bones or other items. Addison's disease, parasites, kidney failure or diabetes mellitus can all cause vomiting. I would recomend getting Rye to vet for physical exam. Depending on exam findings they may recommend tests or may be able to start symptomatic care to help stop the vomitting and get him feeling better. The sooner he is evaluated and treated the easier treatment may be. If he becomes dehydrated or loses too much protein or nutrients from vomiting he may require fluid therapy or more aggressive treatment to recover.
I hope Rye feels better soon. Thank you for using Petco Pet Education Center, formerly Petcoach.
