Hello, Bella is not eating,did not eat breakfast, lunch, and for dinner a made her some rice and eat very little. she it has been acting mostly normal, but a little down. She has been pooping bright yellow mucus on and off for a couple of weeks. Today she pooped yellow and blood. Her stomach is making loud noises. I saved the poop to have the vet check it whenever they open.

I'm sorry to hear that Bella isn't feeling well or eating much today. I can see a good bit of blood and mucus in her stool. As Dr. Melanie mentioned, this could be due to parvovirus or hemorrhagic gastroenteritis, as well as parasites or chronic intestinal diseases (such as inflammatory bowel disease or exocrine pancreatic insufficiency). It's always concerning to me when very small puppies aren't eating well because they are more susceptible to the effects of hypoglycemia (low blood sugar) than older and larger dogs. It would be best to have Bella examined by a vet pretty urgently because she might need to be hospitalized for IV fluids and monitoring. I'm glad to hear that you've saved a stool sample because your vet will likely need to perform a fecal flotation test to microscopically check for parasite eggs. I hope that Bella feels better soon!

    Poor Bella. I'm quite concerned that she did not eat at all today and is pooping diarrhea with blood. It could be she has Parvo if she is not vaccinated, hemorrhagic gastroenteritis, a foreign body, or she may have eaten something toxic. I think it's best she sees a vet now. I would take her into an ER vet immediately. Best of luck.
