Ive been reading alot of negative reviews on this antibiotic shot and I'm scared now. Our 14 year old dog was diagnosed with a bad UTI on Saturday morning and we were told by our vet that this shot would help. Shes been throwing up, having the runs and not wanting to eat. I know its going to take a few days to get her feeling back to herself but upon reading further adverse reactions, im scared. What are your thoughts?
