Why is my dog depressed, not eating, and throwing up yellow foam?

Updated On September 23rd, 2025

Pet's info: Dog | German Shepherd | Female | unspayed | 5 years and 4 months old | 75 lbs

Our dog Sammy isn't eating very much and just seems so depressed lately. We tried to mix some tuna in her food and she's barwly touching it. She has thrown up at least once and it was yellow and foamy. What are some things that could be wrong with her?

HI, thanks for using Petco Pet Education Center, formerly Petcoach! I am sorry Sammy is sick! There are many reasons for vomiting. Since Sammy is not spayed, anytime a female intact dog is sick, we worry fist about an infected uterus (pyometra). A pyometra is a surgical emergency. Other causes of vomiting and decreased appetite are: viral or bacterial infections, foreign body ingestion (something is stuck), dietary indiscretion (she ate something gross), intestinal parasites, toxin ingestion, pancreatitis, inflammatory bowel disease, food sensitivities or food allergies and metabolic issues (liver or kidney disease). I recommend that you take her to the Vet today, since it is Friday. The Vet will perform a physical exam and after will likely recommend blood work and/or belly X-rays. I hope this helps and I wish Sammy a speedy recovery!

    Sake sounds very sick. She could have a stomach illness, may have eaten something rotten, could have a foreign body, or pancreatitis. I also see she isn't spayed, and her symptoms could be due to a pyometra. A pyometra is an infection of the uterus that is fatal without treatment. The best thing to do is take her into a vet immediately to get her symptoms diagnosed and treated. If she does have a pyometra, spaying her is part of the recommended treatment. Best of luck.
