My 12-year-old dog won't eat, is thin, and throws up yellow liquid.

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Male | unneutered | 11 years and 7 months old | 50 lbs

My dog has not eaten for months and it started when 2 of our female dogs got their period. He is already 12 years old and got super thin since then. We have tried everything and he does not want to eat. Vomits yellowish liquid

I'm concerned that Shin is sick and that he could have something serious going on like diabetes, kidney failure, liver disease, heart disease, or cancer causing him to not eat, lose weight, and vomit. He sounds extremely sick and he needs to see a vet immediately. I'd take him into one now for a geriatric blood panel and urinalysis. Please take him into a vet now. Best of luck.
