Sometimes, though not always, the reason behind ‘why is my Chihuahua throwing up’ can be identified and either corrected, acknowledged, or addressed in an attempt to solve a more serious underlying health issue.

Let us find out the different answers to ‘why is my Chihuahua throwing up?’

Why is My Chihuahua Throwing Up?

Why is my Chihuahua throwing up?

To answer the question ‘why is my Chihuahua throwing up?’ you need to take a closer look at the vomit. As disgusting as that might sound, it is necessary to decide your next course of action.

Get one-on-one with the vomit and closely observe its color, composition, and volume.

Next, move on to your Chihuahua and make an observation of its health and body. Does it seem normal? If possible assess its abdomen. Is it swollen?

Take steps to rehydrate your Chihuahua. (If your Chi shows interest- let it sip water or give it an electrolyte solution such as Pedialyte®.)

Move on to the next section if your Chi has vomited all of its undigested food out. This is known as regurgitation. I have also covered in detail what different colored vomits mean and when to see the vet.

Why is my Chihuahua Regurgitating its Food & What to Do About It

Why is my Chihuahua throwing up?

Regurgitating is an act of emptying the stomach before the initial steps of digestion have occurred.

A) Examine your Chihuahua

In every case of regurgitation, you must examine your Chihuahua in the following manner:

  1. With your dog standing, kneel beside it.
  2. Place one hand, palm facing up, on its abdomen just behind its rib cage.
  3. Form a ‘U’-shape with your thumb on one side and four fingers on the other side and gently lift, squeeze, and slide your hand back and forth on your dog’s underbelly.
  4. Check for areas of tenderness, discomfort, or pain.
  5. Lift your pet’s tail and observe signs of intestinal parasite, diarrhea, or blood, or swelling.
  6. Also check your pet’s gums.

B) Check for lumps and bumps

  1. If your Chihuahua’s lymph nodes are swollen, you might feel them along the neck on the sides of its throat.
  2. If there is a bump/lump, it could even indicate an upper respiratory tract infection. Your Chi might need antibiotics so please consult your vet.
  3. If you felt lumps or bumps along the abdominal area, or your Chi flinches when you touch its belly, there could be an obstruction or blockage in its digestive tract. Please take your pet for an X-ray to the vet.

C) Check your pet’s vomit

  1. Do you see any inedible objects in the vomit? Are there any plants or animal matter or spicy substances in it?
  2. Your dog’s stomach might contain harmful objects or toxic foods which is why it may have vomited. Let your pet rest. Once the toxins are out, your Chihuahua will feel better. Do not feed it any solid food for a few hours. You can give your Chi some water and electrolyte solution to rehydrate it.
  3. As long as your Chi continues to act normal, s/he should be fine. If not, please see your vet.

D) Conduct an oral examination

  1. If your Chihuahua has pain, broken teeth, or a dental abscess, then these issues can also cause regurgitation.
  2. If your Chihuahua’s gums are pale to white in color, please see your vet immediately.

E) Observe if your Chihuahua is coughing

  1. In case of forceful coughing or even an infection like kennel cough, a dog might bring out its stomach contents.
  2. Seek treatment for the cough, and the regurgitation will also cease.

Why is my Dog Vomiting White Foam?

A) Causes

A Chihuahua throwing up white foam isn’t usually too serious. It could be stress-related or simply something bad that it ate. The white foam is just saliva and since there is no yellow in it, it indicates absence of bile.

B) What to do

Try to feed your Chihuahua small, frequent meals. The empty stomach may be causing acid reflux which may cause your dog vomiting white foam.

Why is my Chihuahua Throwing up Yellow Foam?

Why is my Chihuahua throwing up?

This is usually seen in Chihuahua puppies. A Chihuahua pup under the age of 1 year old might regularly throw up yellow foamy vomit.

The first time it happens, it can be rather alarming to a Chihuahua owner. In most cases though, this type of throwing up is benign and does not warrant a trip to the veterinarian.

A) Causes

A number of reasons can cause Chihuahua throwing up yellow foam:

  • Stress
  • Upset stomach
  • Fever
  • Empty stomach for prolonged period – The most likely cause is that you need to feed your Chihuahua. Its stomach is empty and that can cause buildup of stomach acid and bile. Some Chihuahuas throw up yellow bile early in the morning. This is usually after ‘fasting’ through the night.
  • Bilious vomiting syndrome – Often, Chihuahuas suffer from Bilious Vomiting Syndrome or BVS. It leads to a buildup of yellow bile in the stomach that causes the dog to throw up late at night or early morning (when its tummy is empty). Try feeding your Chi later at night and also smaller, frequent meals through the day to prevent this.

B) What to do

  1. Consider when and what you feed your Chi. Chihuahuas are very sensitive dogs. They could have food allergies and intolerance. Many types of foods could cause your Chi to vomit yellow bile since certain ingredients in its dog food irritate its delicate tummy.
  2. Find out more about the type of food your Chihuahua can safely eat. Remember: no two dogs are the same. Some Chihuahuas are even allergic to chicken.

Why is my Chihuahua Throwing up Regularly After Meals?

common health problems in Chihuahuas

This type of vomiting occurs due to one or more of the following three factors:

A) Causes

  • The type of food you serve your pet
  • How often you feed it.
  • The size of the meal you feed.

B) What to Do

  1. Chihuahuas are small dogs with small stomachs and they rapidly burn energy, especially a Chihuahua puppy. That is why a young Chihuahua might do better with three to four small meals instead of one or two large meals.
  2. Avoid feeding ‘large’ meals to your Chihuahua all at once, as that could be the reason behind its vomiting.
  3. Consider food allergies. If needed make gradual dietary changes like switching to hypoallergenic food or try rotating the protein in food.

Why Is My Chihuahua Eating Grass and Throwing Up?

Why is my Chihuahua throwing up?

A) Causes

  • Chihuahuas often eat grass when they have an upset stomach or indigestion.
  • Eating grass aids digestion and sometimes dogs regurgitate partially digested or undigested grass to bring out the stomach acid, bile, and other irritants from their digestive tract. This is normal and nothing to worry about.
  • Sometimes, Chihuahuas eat fresh grass after rains as a pre-meal salad.

B) What to do

Make sure that the grass it eats is not treated with any harsh chemicals or pesticides. Check with your vet if your Chihuahua’s grass eating gets obsessive.
