If your Chihuahua is throwing up, you need to immediately determine the cause. Chihuahuas are small dogs, and their bodies cannot handle vomiting like larger breeds can.
Vomiting can quickly lead to dehydration, which can be deadly for Chihuahuas. There are many possible reasons why your Chihuahua might be throwing up, so it is important to take them to the vet as soon as possible.
In this blog post, we will discuss the causes of vomiting in Chihuahuas, and how to treat it. We will also provide some tips for preventing your Chihuahua from throwing up in the first place.
Why Do Chihuahuas Throw Up?
The most common reasons why Chihuahuas throw up include stress, anxiety, overeating, and eating too fast. Chihuahuas are prone to anxiety and stress, which can lead to vomiting.
Let us explore these reasons more closely:
Stress and Anxiety
One of the most common reasons for Chihuahua vomiting is stress and anxiety. Chihuahuas are small dogs, and they are often terrified of loud noises, unfamiliar people, and new environments.
This can lead to severe anxiety, which can cause your Chihuahua to throw up. If you think that stress and anxiety are the cause of your Chihuahua’s vomiting, you should take them to the vet as soon as possible.
Your vet will be able to prescribe medication that can help relieve your Chihuahua’s anxiety.
Overeating
Another common reason for Chihuahua vomiting is overeating. Chihuahuas have small stomachs, and they cannot eat as much as larger breeds.
If you think that your Chihuahua has overeaten, you should take them to the vet as soon as possible. Your vet will be able to prescribe medication that can help relieve your Chihuahua’s vomiting.
Eating Too Fast
If your Chihuahua eats too quickly, he may end up throwing up his food. Chihuahuas are known for being very enthusiastic eaters and they sometimes forget to chew their food properly before swallowing. This can lead to indigestion and vomiting.
To prevent your Chihuahua from eating too fast, try feeding him smaller meals more often throughout the day instead of one large meal. You can also try using a slow feeder bowl that has raised ridges or obstacles to make your Chihuahua work a little harder to get his food.
If your Chihuahua is still throwing up despite taking these precautions, he may have an underlying medical condition and you should take him to the vet for a checkup.
Medical Conditions
There are a number of medical conditions that can cause vomiting in Chihuahuas. Common causes include:
- Gastritis: Gastritis is an inflammation of the stomach lining that can be caused by a viral or bacterial infection, food allergies, or eating something that doesn’t agree with your Chihuahua’s stomach.
- Pancreatitis: Pancreatitis is an inflammation of the pancreas and it can be very painful. It can be caused by consuming too much fat, drinking alcohol, or certain medications.
- Liver Disease: Liver disease can be caused by a number of things, including genetics, infection, cancer, or ingesting toxins. Liver disease can be manifested in a number of ways, including vomiting.
- Kidney Disease: Kidney disease is a common problem in older Chihuahuas. It can be caused by infection, cancer, or ingesting toxins. Kidney disease can cause your Chihuahua to feel very ill and vomit frequently.
If you suspect that your Chihuahua’s vomiting is due to a medical condition, it’s important to take him to the vet right away for treatment. Don’t try to treat the condition at home, as this could make it worse.
Vomiting After Surgery
If your Chihuahua has recently had surgery, he may vomit as his body adjusts to the anesthesia. This is usually not a cause for concern and will resolve on its own within a day or two.
However, if your Chihuahua continues to vomit or seems to be in pain, please contact your vet.
Chihuahua Throwing up Yellow Foam
If your Chihuahua is throwing up yellow foam, it could be a sign of liver disease. Liver disease can be caused by a number of things, including genetics, infection, cancer, or ingesting toxins.
If your Chihuahua is throwing up yellow foam and seems to be in pain, please take him to the vet immediately. If liver disease is caught early, it can be treated and your Chihuahua can live a long and healthy life.
If your Chihuahua is throwing up yellow foam and you are not sure what to do, please contact your veterinarian. They will be able to help you determine the cause of the vomiting and create a treatment plan.

Chihuahua Throwing Up and Shaking
If your Chihuahua is throwing up and shaking, it could be a sign of something serious. Vomiting and shaking could be a sign that your Chihuahua is suffering from a condition called bloat.
Bloat is a condition that can be fatal if not treated immediately, so it’s important to take your Chihuahua to the vet right away if you think they may be suffering from it. Other potential causes of vomiting and shaking in Chihuahuas include:
- Hypoglycemia: Chihuahuas are prone to hypoglycemia, or low blood sugar. This can cause them to vomit and shake.
- Injury: If your Chihuahua has been in an accident or has suffered some other type of injury, it could be causing them to vomit and shake.
- Parvovirus: Parvovirus is a virus that can be deadly to Chihuahuas. It can cause them to vomit and shake, as well as other symptoms such as diarrhea, lethargy, and loss of appetite. If left untreated, parvovirus can be fatal.
- Distemper: Distemper is another virus that can be deadly to Chihuahuas. It causes similar symptoms to parvovirus, including vomiting and shaking. Distemper can be deadly if left untreated, so it’s important to take your Chihuahua to the vet if you think they may have it.
- Kennel cough: Kennel cough is a respiratory infection that can cause your Chihuahua to vomit and shake. It’s usually not fatal, but it can be very contagious, so it’s important to take your Chihuahua to the vet if you think they may have it.
If your Chihuahua is throwing up and shaking, don’t wait to see if the symptoms go away on their own. Take them to the vet right away to get them checked out and determine the cause of their vomiting and shaking.
Chihuahua Throwing up Clear Liquid
If your Chihuahua is throwing up clear liquid, it’s likely due to gastroenteritis. This is an inflammation of the stomach and intestines that can be caused by a virus, bacteria, or parasites.
Treatment usually involves letting your Chihuahua rest and recuperate, and providing them with small meals of easy-to-digest food. If your Chihuahua is still throwing up after a day or two or showing other signs of illness, then it’s time to take them to the vet.
However, there are times when throwing up clear liquid can be a sign of something more serious. If your Chihuahua is also shaking, has diarrhea, or seems to be in pain, then it’s time to take them to the vet because it could be a sign that they’re suffering from dehydration.
Dehydration is a serious condition that can be fatal if not treated immediately, so it’s important to take your Chihuahua to the vet right away if you think they may be dehydrated.
Chihuahua Throwing up Brown Liquid
A Chihuahua that’s throwing up brown liquid could mean that your dog has eaten poop or has just regurgitated dog food. While these do not usually cause concern, there are times when brown vomit can be a sign of something more serious.
If your Chihuahua is throwing up brown liquid, take him to the vet for an examination to be sure. The vet will likely recommend some tests, such as a fecal exam and X-rays, to determine the cause of the problem. Treatment will be based on the underlying diagnosis.
In the meantime, you can try feeding your Chihuahua small meals several times a day instead of one large meal. This may help settle his stomach and prevent vomiting.
Give your Chihuahua plenty of fresh water to drink, too. Avoid giving him fatty or spicy foods, as these can make his GI problems worse.
Call the vet immediately if your Chihuahua continues to vomit, despite treatment, or if he begins to show other signs of illness, such as lethargy or diarrhea. Untreated GI problems can lead to serious health complications, such as dehydration.
With prompt treatment, most Chihuahuas make a full recovery from GI problems. However, some may require lifelong management if they have a chronic condition, such as food allergies.
Are There Any Home Remedies for a Chihuahua’s Upset Stomach?
Yes, there are a few home remedies you can try to settle your Chihuahua’s upset stomach. However, it’s important to keep in mind that these remedies are not a substitute for veterinary care.
If your Chihuahua has an upset stomach, you can try feeding him small meals of easy-to-digest food, such as boiled chicken and rice. You can also give him plenty of fresh water to drink.
Pumpkin, chicken broth, and yogurt are also good options for Chihuahuas with an upset stomach. Just make sure to give these foods in moderation.
Some over-the-counter medications may help settle your Chihuahua’s stomach, but it’s important to talk to your vet before giving them to your dog. Some human medications, such as ibuprofen and acetaminophen, can be toxic to dogs.
Call the vet immediately if your Chihuahua’s symptoms don’t improve within a day or two, or if he begins to show other signs of illness, such as lethargy or diarrhea. Don’t wait to see if the symptoms go away on their own.
Chihuahuas are small dogs, and they can become dehydrated quickly if they’re not treated promptly. With prompt treatment, most Chihuahuas make a full recovery from an upset stomach.
When Should I Take My Chihuahua to the Vet?
Although there are times when vomiting is considered normal, such as when your Chihuahua eats too fast or swallows a lot of air, there are times when it can be a sign of something more serious. If your Chihuahua is vomiting frequently, has blood in their vomit, or is showing other signs of illness, it’s time to take them to the vet immediately.
Do not wait until your Chihuahua’s vomiting becomes severe before seeking medical attention, as this could be life-threatening. If your Chihuahua is showing any other signs of illness, such as lethargy, diarrhea, loss of appetite, or increased thirst, these may also be indicative of a more serious problem and warrant a trip to the vet.
At your Chihuahua’s vet appointment, they will likely perform a physical examination and may also recommend blood and urine tests to help diagnose the problem. Depending on the cause of your Chihuahua’s vomiting, treatment may be as simple as changing their diet or giving them medication to settle their stomach.
In more severe cases, hospitalization and intravenous fluids may be necessary. If your Chihuahua is vomiting frequently or showing other signs of illness, don’t wait to take them to the vet. Early diagnosis and treatment can make a big difference in their prognosis.
Call your veterinarian immediately if you think your Chihuahua might have ingested something poisonous. Do not try to make your Chihuahua vomit unless instructed to do so by a professional.
Ingesting something poisonous is a serious matter that requires immediate medical attention. This is because vomiting can worsen the situation by causing more of the poison to be absorbed into your Chihuahua’s system.
