My dog had his teeth cleaned about 3 weeks ago, and took antibiotics for a week. About a week ago he started acting weird, lethargic, throwing up, then not eating, and having trouble peeing. His stomach also looked protruded when lying on his side. Took him to vet who said his red blood cell count went down 20 points from the time he had the dental work till now, plus there was some little round objects that showed up in his x-ray. He is having more test done now, any suggestions on what could be the problem. Temp was 102.
