Warning Signs of Serious Disease in Dogs
1. Protracted vomiting and diarrhea
There are at least 63 causes of vomiting in dogs, but the most common cause is simply known as dietary indiscretion. Dogs who get into the trash, eat animal carcasses or drink pond water all can end up with very dicey gastrointestinal tracts.
Other more serious causes of vomiting and diarrhea include diseases of the pancreas, liver or kidney, or other primary intestinal diseases such as a blockage, parasites, cancer, ulcers or inflammation. Your veterinarian may need laboratory tests and X-rays to sort these out.
The first important criteria is to confirm that your dog is drinking water and able to hold it down without vomiting. Then, evaluate your dog’s attitude: Is she lethargic, lacking appetite and not interested in her usual activities? This can be a sign of serious underlying disease. Finally, note whether the vomiting and diarrhea appear to be worsening or fail to improve in 24 hours. Without improvement in 24 to 36 hours, it is time for a visit with your veterinarian to rule out serious disease.
