Why is my 9-year-old Golden Retriever not eating and lethargic?

Updated On September 23rd, 2025

Pet's info: Dog | Golden Retriever | Female | spayed | 90 lbs

Recently, my dog hasn't been eating her food or treats, for the past 3 days. It was small at first but continued to get worse. She's also been more lethargic and won't get up as often, or go upstairs. My dog is a Golden retriever and she's nine years old.

Poor Mazy! It definitely sounds like something isn't right. There are many different things that could cause decreased appetite and lethargy, so it's hard to say what might be wrong without being able to examine her and run some tests. She could have anything from liver or kidney disease, to heart disease, arthritis pain, a GI problem of some kind, or even some type of cancer. I would recommend taking Mazy to the vet for an exam when you are able to. He/she can do blood work and x-rays if needed to help diagnose the problem and get her started on appropriate treatment depending on what is found.
