why is my shih tzu vomiting
Shih Tzu vomiting (being sick) is a fairly common issue that can happen for various reasons. Often, it’s something minor, like a change in diet, eating food from the garbage, or eating too fast. Sometimes, it’s a sign of something more serious. Understanding the causes, types, and treatments for Shih Tzu vomiting is crucial to keeping your furry friend healthy.
In this article, we’ll discuss everything about vomiting in Shih Tzus including its causes, types, and treatments.
Types of Shih Tzu Vomiting
Shih Tzu vomiting can be classified by its duration and characteristics. Vomiting can be acute if it lasts for up to four days or chronic if it happens regularly over time. Here are the different types of vomiting in Shih Tzus based on its appearance:
- Bilious Vomit: This type includes bile fluid, which is yellowish and comes from the gallbladder.
- Food Vomit: This occurs when your Shih Tzu vomits undigested or partially digested food.
- Mucous Vomit: Mucus is present in this type of vomit.
- Hematic Vomit: This is when the vomit contains blood.
Additionally, Shih Tzu vomiting may include grass, a brownish fluid, or have a fecal odor. Each type can signal different underlying issues, so it’s essential to recognize and address them quickly.
Common Causes of Shih Tzu Vomiting

Several factors can cause Shih Tzu vomiting, all of which irritate the stomach or intestines. Identifying these causes helps in responding appropriately.
Stomach Flu
Gastroenteritis in Shih Tzus works much like it does in humans, causing vomiting and sometimes diarrhea. This condition usually results from consuming bad food or a viral or bacterial infection. Most cases are treatable at home, but persistent symptoms require a vet’s attention.
Ingestion of a Foreign Object
If your Shih Tzu swallows something inappropriate, it could cause vomiting as the body attempts to expel it. This can lead to stomach or intestinal obstruction, a serious condition requiring immediate veterinary care.
Intestinal Parasites
Parasites like tapeworms and roundworms can disrupt your Shih Tzu’s digestion, leading to vomiting, diarrhea, and abdominal swelling. Regular deworming by a vet can help prevent this issue.

Viral Infections
Serious viruses such as parvovirus or distemper can cause severe vomiting, especially in puppies. These conditions are contagious and potentially fatal, so immediate veterinary care is necessary.
Toxic Food or Food Allergies
Certain foods, plants, or spoiled items can be toxic to your Shih Tzu, leading to vomiting and other symptoms like diarrhea or swelling. Identifying and removing the allergen from your Shih Tzu’s diet is crucial.
Tumors
Older Shih Tzus are more prone to developing tumors, which can cause vomiting along with other symptoms. Regular vet check-ups are important for early detection.
Inflammatory Bowel Disease (IBD)
This chronic condition causes inflammation in the intestines, leading to vomiting after meals. A specialized diet and controlled exercise can help manage this condition.
Changes in Diet
A sudden change in diet can easily upset your Shih Tzu’s stomach, leading to vomiting. This is because their digestive system isn’t accustomed to new ingredients or food textures. When introducing new food, it’s essential to do so gradually. Start by mixing a small amount of the new food with the old one. Gradually increase the new food’s portion over a week or more, depending on how sensitive your Shih Tzu is. This slow transition allows their digestive system to adjust without causing discomfort. If you notice any signs of vomiting or diarrhea during the transition, slow down the process even more. Always choose high-quality, easily digestible food to minimize the risk of digestive upset.
Eating Very Fast
Shih Tzus are known for their enthusiasm, especially when it comes to mealtime. However, eating too quickly can cause them to vomit, often accompanied by white foam. This happens because their stomach doesn’t have time to properly digest the food, leading to regurgitation. To help prevent this, consider dividing their food into smaller, more frequent meals. Another effective method is to use a slow feeder bowl. These bowls are designed with ridges or obstacles that force your dog to eat more slowly, reducing the risk of vomiting. Additionally, avoid feeding your Shih Tzu immediately after vigorous activity, as this can also lead to vomiting.

Antiparasitic vaccines or products
Vomiting is a common side effect after your Shih Tzu receives vaccines or antiparasitic treatments, particularly in puppies. Their bodies are reacting to the new substances introduced, which can temporarily upset their stomachs. Typically, this type of vomiting is short-lived and should resolve within 24-48 hours.
During this time, ensure your puppy stays hydrated and comfortable. If the vomiting continues beyond this period or is accompanied by other symptoms like lethargy or diarrhea, it’s important to consult your vet. They may recommend a different approach or additional treatments to help alleviate these side effects.
Why Is My Shih Tzu Puppy Vomiting?

In the previous section, we have already discussed some of the most common causes of vomiting in Shih Tzus. However, we want to mention those that are most common in Shih Tzu puppies as they do sometimes differ.
- Canine Parvovirus: This highly contagious and deadly virus causes severe vomiting and diarrhea in puppies. It primarily affects unvaccinated or partially vaccinated puppies. The virus attacks the gastrointestinal tract, leading to intense dehydration and weakening the immune system. Immediate veterinary care is crucial. Treatment typically involves intravenous fluids, anti-nausea medications, and supportive care to help the puppy fight off the virus.
- Change in Diet: Puppies have sensitive digestive systems, so a sudden change in diet can easily cause vomiting and diarrhea. This can happen if they switch from their mother’s milk to solid food or if they are moved to a new home with different food. To avoid this, any dietary changes should be made gradually, mixing the old food with the new one over the course of a week or more. This gradual transition helps their digestive system adjust without causing discomfort.
- Vaccination and Deworming: It’s common for Shih Tzu puppies to vomit after receiving vaccinations or deworming treatments. Their bodies are responding to the new substances introduced during these procedures. Typically, this reaction is mild and should not last more than 24-48 hours. However, if vomiting persists or is accompanied by other symptoms like lethargy or loss of appetite, it’s important to consult your vet. They can provide guidance on how to manage these side effects and ensure your puppy remains healthy.
Yellow Vomiting in Shih Tzus
Yellow vomiting in Shih Tzus typically indicates that your dog is expelling bile. Bile is a digestive fluid produced by the liver and stored in the gallbladder, and it’s released into the stomach when it’s empty. This type of vomiting often happens early in the morning or late at night, especially if your Shih Tzu hasn’t eaten for several hours.
Common causes include infectious diseases, food intolerance, or stress. If your Shih Tzu vomits yellow bile frequently, it could lead to dehydration and more serious health issues. It’s important to visit the vet to determine the underlying cause and prevent any further complications. Your vet may recommend feeding smaller, more frequent meals to keep your Shih Tzu’s stomach from being empty for too long.

My Shih Tzu Vomits Undigested Food
If your Shih Tzu vomits undigested food immediately after eating, this is likely regurgitation, not vomiting. Regurgitation occurs when food is expelled from the esophagus before it reaches the stomach. Unlike vomiting, regurgitation is a passive process, meaning it happens without the heaving and nausea typically associated with vomiting.
Common causes include eating too fast, which can overwhelm your Shih Tzu’s digestive system, or food allergies, where the body quickly rejects the ingested food. To manage this issue, feed your Shih Tzu smaller portions more slowly. You might also want to consider using a slow feeder bowl or feeding them from a raised platform, which can help reduce the speed at which they eat. If the problem persists, a visit to the vet is recommended to rule out any underlying health issues.

My Shih Tzu Vomits Blood
Finding blood in your Shih Tzu’s vomit is alarming and requires immediate attention. While the blood could be from a minor issue, such as a cut in the mouth or throat, it could also indicate a more serious problem like gastrointestinal inflammation, poisoning, or tumors.
In some cases, if your Shih Tzu has swallowed a sharp object, it could cause internal injuries leading to bloody vomit. Gastric ulcers, which can develop from prolonged use of certain medications or stress, are another possible cause. If you notice blood in your Shih Tzu’s vomit, it’s crucial to seek veterinary care right away. Your vet will likely perform diagnostic tests, such as blood work or imaging, to determine the cause and provide appropriate treatment.
My Shih Tzu Vomits White and Foamy Substance

When your Shih Tzu vomits a white, foamy substance, it’s usually a sign that bile is being expelled. This often occurs when your Shih Tzu’s stomach is empty, which can happen if they haven’t eaten for an extended period or have a condition like gastritis, which inflames the stomach lining. Another potential cause is kennel cough or other respiratory issues, where the foam results from excessive mucus production.
In more serious cases, white foam vomiting could be related to liver or kidney problems, especially in older dogs. Regular veterinary exams are essential for early detection and treatment of these issues. If your Shih Tzu consistently vomits white foam, it’s important to consult with your vet to determine the underlying cause and develop a treatment plan.
Diarrhea and Vomiting in Shih Tzus
When vomiting is accompanied by diarrhea, it often points to gastrointestinal issues. These symptoms can range from mild, such as dietary indiscretion where your dog eats something they shouldn’t, to more severe conditions like parvovirus, which requires immediate veterinary attention.
In cases where both vomiting and diarrhea occur, dehydration becomes a significant concern, particularly in puppies and older dogs. It’s important to ensure your Shih Tzu stays hydrated and seek veterinary care promptly. The vet may conduct tests to identify the cause and recommend appropriate treatment, which might include dietary changes, medications, or even hospitalization in severe cases.
Treatment for a Vomiting Shih Tzu

Treating Shih Tzu vomiting depends on identifying the underlying cause. For mild cases, such as indigestion from eating too quickly or a minor dietary indiscretion, simple home remedies like fasting for 24 hours and then offering a bland diet of boiled chicken and rice can be effective. However, if the vomiting is due to a more serious condition, such as a viral infection or poisoning, veterinary intervention is required.
Your vet may prescribe medications like antibiotics, anti-nausea drugs, or stomach protectors to treat the specific issue. In cases of foreign object ingestion or severe gastrointestinal blockages, surgery may be necessary. Always consult with your vet before starting any treatment to ensure it’s appropriate for your Shih Tzu’s condition.
My Shih Tzu Is Vomiting a Lot—What Should I Do?
If your Shih Tzu is vomiting frequently, it’s important to act quickly to prevent dehydration and identify the cause. Start by withholding food for 24 hours, giving their stomach a chance to settle. During this time, make sure they have access to plenty of water to stay hydrated.
After the fasting period, gradually reintroduce food with a bland diet of easily digestible foods like boiled chicken, rice, or pumpkin. Offer small, frequent meals instead of one large meal to avoid overwhelming their stomach. If vomiting continues after this period, or if it’s accompanied by other symptoms like lethargy, fever, or diarrhea, consult your vet immediately. Persistent vomiting can be a sign of a more serious issue that needs professional treatment.
What should you give your Shih Tzu when they vomit?
When your Shih Tzu vomits, you should consider giving them easily digestible foods such as boiled chicken, boiled potato, rice, boiled carrot, boiled pumpkin, and boiled turkey. Since it’s possible that your Shih Tzu doesn’t want to eat after vomiting, give them food in small quantities several times a day. You need to make sure though that you don’t give them too much for them to become so full and may experience vomiting again.
However, if the vomiting is caused by serious diseases where the problem can’t be treated easily, the vomiting will not stop. For this reason, it is important to see the vet, especially if the vomiting continues after a 24-hour fast and the introduction of a soft diet.
When Should You Go to the Vet?
Knowing when to seek veterinary care is crucial for your Shih Tzu’s health. If your dog vomits once or twice but quickly returns to normal behavior and eating habits, it’s likely not serious. However, frequent vomiting, especially when combined with other symptoms like lethargy, fever, or diarrhea, should be a cause for concern.
Puppies and elderly Shih Tzus are particularly vulnerable to dehydration and other complications from vomiting, so prompt action is necessary. If you notice blood in the vomit or stool, or if they are vomiting white foam or bile frequently, it’s essential to visit the vet immediately. Early intervention can make a significant difference in your Shih Tzu’s recovery and overall well-being.
Conclusion
Shih Tzu vomiting can range from a minor inconvenience to a sign of a serious health issue. By understanding the different types, causes, and treatments of vomiting, you can better care for your Shih Tzu and ensure they stay healthy and comfortable. Always monitor your dog closely and consult with your vet whenever in doubt. Taking swift action when necessary will help keep your Shih Tzu happy and thriving.
