Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | unspayed
Today we had to put my dog down. She was very lethargic and vomiting yellow foam. She had no diarreah. When we got her to vet, she didn't move at all. Her eyes were glossy. Her blood pressure was really low. When they took the thermometer out of her she started pooling out blood. The parvo test was negative. But the vet says it was parvo. But there was no diarreah at all

I am so sorry to hear about the loss of your dog. We can occasionally have dogs that may test negative for parvo earlier in the course of the disease, so it is possible if your dog was never vaccinated for parvo and was a young dog (we can see this disease in older dogs, but the majority are 2 years and under). Other possible causes could include hemorrhagic gastroenteritis (HGE), Addison's disease, severe GI parasitism, or toxin ingestion. If you want a more certain answer to what happened you could request that your vet have a necropsy performed on Red's remains.
