Most likely your dog is throwing up bile, which is a yellowish liquid, early in the morning or even sometime in the middle of the night. This occurs because their stomach is empty and has been for some time. This is referred to as reflux gastritis.
Acid Reflux

Is your dog vomiting white foam in the morning before eating? It could mean she has reflux gastritis, also called acid reflux. This condition occurs when bile that`s in your dog`s intestines after a meal moves backward into the stomach after a long period of not eating (e.g., overnight).

If your dog is throwing up, but still acting otherwise normal, it`s possible that your pet has either chronic gastritis (inflammation of the stomach) or food indiscretion. Food indiscretion in dogs is very common when they get so excited about eating that they eat too fast or too much, and some of it comes back out.
A dog throwing up bile is of concern because it could be a symptom of a number of potentially dangerous gastrointestinal conditions such as parasitic infections, ulcers, and certain kinds of cancer. Additionally, bile is acidic and can cause wear and damage to your dog`s esophagus, leading to ulcers if not treated.
Also called reflux gastritis, bilious vomiting syndrome is a fairly common cause of vomiting, particularly in older dogs. Typically, dogs with this condition vomit yellow bile in the morning before they have a chance to eat breakfast, but act normally after eating.
You shouldn`t worry immediately if this happens on a particularly hot day or after an abnormally excessive workout. However, if your dog keeps throwing up clear liquid, this could suggest a more serious problem. Hyperthyroidism, pancreatitis, or parasites could cause your dog to throw up clear fluid.
Dogs sometimes vomit up yellow foam. This yellow foam is a form of bile, or digestive fluid, that is produced in the liver, stored in the gallbladder, and released into the small intestine, just below the stomach. This yellow foam usually means that its stomach is empty and the bile is causing stomach irritation.
If you eat before sleeping and experience heartburn when you wake up, it`s possible that the undigested food from the night before is still around to bother you in the morning. It takes the stomach around four to five hours to fully empty after a meal, so eating at least three hours before bedtime is advised.
Bile reflux involves fluid from the small intestine flowing into the stomach and esophagus. Acid reflux is backflow of stomach acid into the esophagus. These conditions are often related, and sometimes differentiating between the two can be difficult. Bile is a digestive fluid made by the liver.
‍Why do dogs vomit white foam? White foam, a makeup of mucus and fluid from a dog`s respiratory tract, can appear as vomit for several reasons. It could be because of gastrointestinal parasite infection (or other infections), pancreatitis, foreign body ingestion or consumed toxins, Dr.
If your dog is suffering from bilious vomiting, you should try to provide them with their normal dog food just before they go to bed. Then, you should feed them again right after you get up in the morning. This is especially important if you notice that the vomiting episodes typically happen first thing in the morning.
If your dog vomits bile but appears to have no other alarming symptoms and returns to normal afterwards, taking them to the vet should not be necessary. If they throw up bile twice a week or daily, take them to the vet. Pancreatitis is an inflammation of the dog`s pancreas.
If you see your dog vomiting yellow bile when he also has constipation or can`t keep any fluids down … take him to the vet right away. If your dog repeatedly vomits yellow or white foam, or he`s trying to vomit with nothing coming out, it could be a sign of bloat (also called GDV – gastric dilatation and volvulus).
What are the clinical signs of pancreatitis? The most common clinical signs include nausea, vomiting, fever, lethargy, abdominal pain, diarrhea, and decreased appetite. During an attack, dogs may take a `praying position`, with their rear end up in the air and their front legs and head lowered onto the floor.
Acute pancreatitis can occur after a dog eats a fatty food such as pork, beef, and some other human foods. Dogs that get into garbage can develop pancreatitis. Pancreatitis can also have other causes, including certain medications and some viral or bacterial infections.
Signs that a dog has liver disease can vary and include loss of appetite, vomiting, stomach ulceration, diarrhea, seizures or other neurologic problems, fever, blood clotting problems, jaundice (a yellow tinge noticeable in the skin, mucous membranes, and eyes), fluid collection in the abdomen, excessive urination and …
Your puppy will vomit and have diarrhea if canine parvovirus is present in their system. Vomit may be clear or a yellow or brown color, and diarrhea will often contain blood and be a light yellow or mustard colored hue.
What can I give my dog for throwing up bile? If your dog is otherwise bright and has only been sick once or twice you could try feeding them bland easy-to-digest food little and often. This includes a specially formulated sensitivity diet, or – in an emergency – cooked chicken, white fish, and white rice.
It`s okay if your dog vomits water occasionally. Dog throwing up water can happen after an intense play on hot days. In most cases, this is normal and nothing to be worried about. But if your dog continues vomiting water, it might indicate serious health issues demanding prompt treatment.
Discussion: Rebound acid hypersecretion lasts more than 8 weeks, but less than 26 weeks after long-term proton pump inhibition. Conclusion: The findings indicate that not only the parietal cell mass, but also ECL cell mass and activity are involved in the mechanism of acid hypersecretion.
With the appropriate treatment, it takes about one month to heal the damage caused by acid reflux. The first treatment step in functional medicine is to remove the problem. If you can stop the acid reflux from occurring by removing its underlying cause, then your body has a chance to heal.
Acid rebound happens when your body makes too much acid after you stop taking an acid-suppressing medication. This extra stomach acid can cause GERD symptoms. These may be similar to, or even worse than, your original symptoms. The symptoms of acid rebound vary from person to person.
The pH of most water is neutral, or 7.0, which can mildly raise the stomach`s pH. However, water can also help digestion and motility of food out of your stomach and into your small intestine. This may help reduce acid reflux symptoms.

Q. My dog has been throwing up a clear liquid (a little slimey) but otherwise acts fine. Could something be wrong?
ANSWER : A. How long has he been doing this?

Q. My puppy is throwing up her food this morning and yellow foamy stuff. Please help!
ANSWER : A. If the vomiting has only occurred once, it may be due to the fact that there was something causing a minor upset stomach in your pup. Yellow foam is often acid, and tummies that are upset or that have been empty for too long can cause this to appear in vomit. It may just be that your puppy needs an extra meal in the day to help keep her stomach happy. Eating a meal too quickly can also cause a pup to vomit up undigested food and foam, and feeding smaller meals more often, or slowing down your dog’s eating can help.

If the vomiting has only happened once, pick up your puppy’s food for an hour or two and then offer a bland meal of plain boiled chicken and plain rice.

Eating something he shouldn’t have, like the trash or rotten food can cause it. Intestinal obstruction can cause vomiting as well. Other causes (non-GI) of vomiting include kidney failure (can be due to many things, such as toxins, kidney stones, cancer) or liver diseases or liver failure.

Q. Nursing dog pups 13 days old has sudden onset of diarrhea and vomiting what can I do
ANSWER : A. You can try with holding food for 12 hours. Offer unflavored Pedialyte if she’ll drink. If she doesn’t vomit or have diarrhea for those 12 hours you can then offer small amounts of a bland diet such as boiled white meat chicken (25%) and boiled white rice (75%) without flavoring or fat added. Offer about 1/4 cup every 2 hours. If she continues to do well and has an appetite do this for 12 hours, then transition back to a normal diet slowly. If she continues to have vomiting or diarrhea I think it’s important that you seek veterinary care, since continual loss of fluid through vomiting and diarrhea while nursing is very dangerous to any dog, but especially to a very small dog like a chihuahua.
