Vomiting can be characterized by a forceful rejection of the contents in the stomach that already have been partially digested. Usually, it happens as a dog has ingested something that’s indigestible, has consumed something too quickly, or has exercised after a huge meal. Before the pup actually throws up, see if there’s a change in their behavior. The majority of the time, before a canine is about to vomit, they’ll generally show symptoms like retching, contractions, drooling, and nausea.
it’s very important to see your veterinarian right away if your dog’s vomiting lasts for more than 24 hours or if it is accompanied by other symptoms such as lethargy, loss of appetite, diarrhea, fever, or other changes in health or behavior.
Reasons why Your Dog is Vomiting White Foam
There are several reasons for vomiting white foam or slime, and some of them are discussed below.
Indigestion
Canine indigestion is one of the common reasons for vomiting white slime in dogs. Indigestion in your dog is as common as in humans; the only difference is that your dog will vomit more than humans.
Normally, when the dog begins throwing up white foam, it means that he is trying to expel the substances that cause irritation in the stomach. Canine Indigestion also occurs as a result of drinking or eating too fast or too much, consuming grass, trash, or rotten foods that will upset the canine digestive system.
Bilious Vomiting Syndrome
Bilious Vomiting Syndrome in dogs is similar to acid reflux in humans. Bile and stomach acid are naturally occurring fluids that aid in the digestion and processing of food. On an empty stomach, however, they can cause irritation. That irritation can lead an otherwise healthy and hungry dog to ignore meals, or, in more extreme situations, vomit to expel the excess. The vomit from Bilious Vomiting Syndrome can be colored yellow, white, green, orange, brown or some mixture.
Bloat
A severe condition, bloat most commonly occurs in deep-chested adult and senior dogs. Bloat causes a dog’s stomach to fill with gas, fluid, or food, making it expand. One of its early symptoms is a dog spitting up white foam.
Besides an enlarged abdomen and vomiting white foam, dogs will suffer several other symptoms from bloat, including the inability to defecate, pale gums, excessive drooling, and coughing.
If you suspect your dog has bloat, take her to your vet immediately.
Kennel Cough
This is a very contagious condition which can be picked up by your pet when he is boarded, has spent time in a shelter or hospital or when he comes into close contact with other canines. It is an upper respiratory infection which can show up within 10 days of exposure. The most frequent symptoms are a dry, honking cough sometimes accompanied by gagging or coughing up white foam.
Pancreatitis
Pancreatitis is another disease where one of the symptoms is your dog vomiting white foam slime. It is marked by inflammation in the pancreas, and other symptoms include weakness, diarrhea, and a lack of appetite. Again, your dog will need help right away if he has this illness.
Kidney Problems
A dog vomiting white foam, if also showing symptoms of lethargy, weakness, or disorientation, may not have anything to do with their stomach and may instead be indicating that they have kidney issues. One big indicator of kidney disease is if a dog has problems urinating. If your dog is showing signs of any of these problems, get them to the vet as soon as possible. If untreated, kidney disease could eventually lead to kidney failure.
Rabies
Rabies is the last, and least likely, culprit for a dog vomiting white foam. We’re all familiar with the image of a rabid dog foaming at the mouth, but regurgitating foam only happens in the very last stages. By the time a dog takes to vomiting white foam, observers will have noticed much more worrisome signs, such as aggressive behavior.
Parvovirus
Parvovirus is a deadly condition that can lead to the death of dogs.
In parvo infection, the inner lining of the intestine is damaged, and when the intestine is damaged, water and food will not be absorbed; as a result, the dog will suffer from malnutrition and dehydration.
During a viral infection, a secondary infection can also appear, and bacteria are seen in the bloodstream.
This combination of malnutrition, dehydration, and infection creates deadly problems.
The common symptoms that appear in Parvo are foamy vomiting and diarrhea.
Treatment
The first step your vet will take is to thoroughly examine your dog. Be sure to provide details to your vet about your dog’s recent and long-term medical history. Include information about anything you suspect your dog might have ingested, like plants, chemicals, or dangerous foods.
Treatment typically begins by administering anti-nausea medications and gastric protectants. Initial doses are usually given via injection to avoid further vomiting. Dogs with dehydration, pancreatitis, or other health concerns may need hospitalization for intravenous fluids and frequent medication dosing.
If the vomiting was caused by toxin exposure, your vet will follow established medical protocols for treatment. This may also include hospitalization.
