Why is my dog still vomiting, wanting food, and losing weight?

Updated On September 23rd, 2025

Pet's info: Dog | Jack Russell Terrier | Female | spayed | 4 years and 7 months old | 19 lbs

For the past two weeks my dog has been vomiting and hospitalised for a bug for several days. She's been a little constipated. X-rays and barium came back clear with food leaving her tummy a little slow apparently. Her bloods for pancreas related issues came back normal. We thought we turned a corner but she keeps vomiting, it's different though, immediately after she wants more food. She's taking tummy settlers and antibiotics. I'm so worried. She's lost over a kilo in 2 weeks.

I am sorry that Daisy is so sick,. It sounds like you have a good vet working hard to make Daisy feel better. I know you said her barium study came back normal however if she is still vomiting it might be time for her to have additional testing. I would recommend if they have not done already blood work to look at the liver , kidney and white/red blood cell function. Also could she have gotten into a toxin or have a foreign object in her abdomen that the barium did not see. Unfortunately medicine is very frustrating because it can take a while to determine the cause of illness. Also I would make sure Daisy does not have a virus like parvo or parasites. I would recommend continuing to discuss options with your vet who is taking care of daisy and I hope she starts feeling better soon!!

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I am so sorry, this is a horrifying story! I agree that either this was a toxin or my other thought was parvo virus. If the puppies and Daisy are not fully vaccinated then parvo is very likely. Toxins can be from malicious causes, contaminated food or the dogs got in to something. I do not think what Daisy is doing is normal. Since you can at least communicate with your vet I would see if they can come to you if you can't take Daisy to them. They can at least do an exam and maybe draw blood they can send out or take back to the clinic with them. I would otherwise start feeding Daisy a bland diet of boiled chicken or hamburger with rice. And I recommend bringing her indoors, even if it is the garage (remove all toxins, poisons and anti-freeze). I hope this helps and I wish Daisy the best!
