Old chihuahua with liver issues: vomiting & diarrhea. What to do?

Updated On September 23rd, 2025

Pet's info: Dog | Chihuahua (Smooth Coat) | Female | unspayed | 12 lbs

My old chihuahua has liver problems and is on medication for that. Lately she’s been having diarrhea normal in color with a little mucus in it. She’s also been vomiting up clear liquid. What should I do to try and help her without taking her to the vet or what could it be causing it?

I'm sorry to hear that Ruthy hasn't been feeling well. It's possible that her vomiting and diarrhea could be associated with her liver disease, but it's equally possible that they're unrelated. Possible unrelated causes could include a gastrointestinal virus, an upset stomach from eating something unusual or new, pancreatitis, parasites, inflammatory bowel disease, among many other conditions. Mucus mixed in with diarrhea indicates that the diarrhea is originating from the colon rather than the small intestine and isn't a huge red flag in and of itself. If Ruthy is eating, drinking and acting completely normally, you can try offering her a bland diet of boiled white meat chicken and white rice for 5-7 days before mixing this bland diet in with her regular food over another 5-7 days. However, if ANYTHING else is unusual - lethargy, loss of appetite, refusal to drink (or drinking too much), weight loss, or worsening vomiting and diarrhea, then Ruthy will need to be evaluated by her vet. While many cases of mild vomiting and diarrhea resolve with a bland diet and a bit of time, others require diagnostic tests to get to the bottom of the issue and treat the underlying problem. I hope that Ruthy makes a speedy recovery!
