Diarrhea In Dogs Accompanied By Vomiting. Your dog may vomit or have diarrhea caused by a viral infection in his intestines, such as rotavirus or coronavirus. Puppies have a tendency to pick up infections that can cause diarrhea.
Dog vomiting and diarrhea may or may not be a serious indication of further health problems, but it is best to err on the side of caution when it comes to the life of a beloved pet. In their haste to remove the harmful substances, your pet’s immune system will react violently, which can result in bloodstains among the vomit and also in the stools. When the vomiting or diarrhea has subsided, keep a close eye on your dog to observe any severe problems that warrant a visit to the vet.
