- Liver or gallbladder issues: Shih tzus are predisposed to liver and gallbladder problems, such as liver failure, bile duct obstruction, and gallbladder disease. These issues can cause the production of yellow bile, which can then be vomited up. If your shih tzu is also sleeping more than usual, this could be a sign that their liver is not functioning properly.
- Pancreatitis: This is a condition in which the pancreas becomes inflamed. It can be caused by a variety of things, including dietary indiscretion, certain medications, and underlying health conditions. Pancreatitis can cause vomiting, diarrhea, abdominal pain, and lethargy.
- Gastrointestinal obstruction: This is a blockage in the digestive tract that prevents food and liquids from passing through. It can be caused by a variety of things, including foreign objects, tumors, and hernias. Gastrointestinal obstruction can cause vomiting, abdominal pain, and constipation.
- Addison's disease: This is a condition in which the adrenal glands do not produce enough hormones. It can cause a variety of symptoms, including vomiting, diarrhea, weight loss, and lethargy.
- Diabetes: This is a condition in which the body does not produce enough insulin or does not use insulin properly. It can cause a variety of symptoms, including vomiting, diarrhea, weight loss, and lethargy.
- Infectious diseases: Several infectious diseases can cause vomiting and lethargy in dogs, including parvovirus, distemper, and leptospirosis. If you suspect your dog may have an infectious disease, it's important to seek veterinary care immediately.
If your shih tzu is vomiting yellow bile and sleeping a lot, it's important to take them to the vet right away. After the vet rules out the above and other possible causes, they can develop a treatment plan for the underlying issue. Early treatment is essential for a successful prognosis.
