Yesterday my puppy had his second round of shots. And I notice he started peeing blood. His been eating and drinking fine. Today he peed dark brown color. Would this be a normal side effect to shots?

Poor Rocky! No, urinating blood is not a normal side effect of vaccinations, so I would definitely recommend taking him back to the vet to have this checked. The vet can do a urinalysis to help determine the problem (possibly a UTI) and get him started on appropriate medication to treat it if needed.
