My unspayed dog is sick after heat: vomiting, not eating. Pyometra?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | unspayed | 1 year and 8 months old | 20 lbs

My dog started bleeding on her third cycle on Oct. 19th. Since then she has been refusing food, and has vomited three times in the past ten days. Every time it is yellow bile so I thought it was because she had gone without food for too long... (which is nothing new for her. She’s always been a picky eater and goes without eating at night sometimes.) this time there was food in it tho... and on top of that, she hasn’t been wanting to play either. I’m getting worried. Does she have pyometra?!

Poor girl. Pyometra doesn't usually cause just bloody discharge. It will be a foul smelling pink discharge or no discharge at all. However, if she had her last heat cycle 1-2 months ago and now appears to be having a similar heat cycle, then I would definitely suspect that she has pyometra. At any rate, because she is so ill, I would highly recommend Zoe see your local vet for a thorough exam and medical care. Any pet that refuses food for more than 24-48 hrs should be seen, because an underlying illness is present that needs to be identified and treated for.
I hope that your pet Zoe is able to make a full and speedy recovery soon! Best of luck and take care.
