My 2-month puppy has no shots, is vomiting, thin. Is it parvo?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | unspayed | 3 lbs

We adopted ellie a month ago and she haven’t got any shots or deworm. She’s 2 months now. I am so worried about her health today. It’s so unusual because she’s usually fat and now she’s so thin and she often sleep too much and vomits. Im so worried she might have parvo. She was rescued from a breeder and she’s a chihuahua mix. If there’s any help can you guys help us please. I want to know her health and what’s wrong.

Based on what you are describing I would be concerned that Ellie has either a heavy intestinal parasite burden or parvovirus. Both can cause weight loss, dehydration, vomiting and diarrhea.

I would recommend taking Ellie to be examined by a veterinarian as soon as possible. She will likely need treatment (for either disease) to be started right away since she is losing weight already. Your vetnwill probably recommend checking a fecal sample and running a parvo test. At the very least she will need to be dewormed and, if healthy enough, start her vaccines.

I hope this helps. Best of luck with Ellie. Thanks for using Petco Pet Education Center, formerly Petcoach.
