To begin, as a summary, we cite the main causes of white vomiting in dogs , however there are many more.
- That the dog eats or drinks water too quickly.
- Let the dog exercise excessively in a short time.
- Gastrointestinal problems, such as gastritis, gastroenteritis, stomach torsion, bilious vomiting or biliary vomiting.
- Respiratory problems, such as tracheal collapse or kennel cough.
- Heart problems, such as heart failure, arrhythmias, murmurs, muscle thickening, or valve stenosis.

In addition, it should be borne in mind that there are some dog breeds that are more likely to vomit white foam, as is the case with brachycephalic dog breeds or breeds with a tendency to suffer from heart problems. Some of the best known are all types of bulldog, pug or pug, boxer and shih tzu.
Below, we explain some of these conditions that cause a dog to vomit white foam. Take note of all this information in order to help your faithful friend, but remember that only a veterinarian can make a diagnosis and indicate treatment.
eat too fast or too much
This is one of the most common reasons why a dog vomits white foam. If you have noticed that your dog seems to be unwell and seeing his symptoms you have thought something like “my dog vomits white slime” or “my dog vomits transparent slime”, it is very likely that he has eaten or drank too much . speed . Normally, if the vomit is like transparent slime, it will be that he has taken a lot of water at once, choked and expelled it, so it is water and slime. On the other hand, if it is white foam, it may be due to eating too quickly or too much and, in addition, in these cases there may also be some remains of food, even whole or little chewed.
It happens in the same way if at the time of serving his food we exceed the portion served, thinking that he will eat in a rationed way by himself, but on many occasions dogs eat until the plate is empty, which causes their diet to be altered.
When vomiting and retching are continuous, it may mean that something is blocked in the dog’s tract or that there is another problem or disease. If this happens, it is best to contact a veterinarian immediately.
You exercise too much
Just as it happens to us, doing a lot of exercise can cause vomiting in dogs . The reasons for this are because, by eliminating too much water when running, they become dehydrated, in addition to the fact that they have also been breathing in a forced way, the latter collaborating with nausea in dogs.
It’s important to exercise your dog in a controlled manner, making sure you don’t exceed his endurance and providing him with a water source whenever he feels thirsty. If you don’t watch this situation, your dog could get heat stroke or faint due to fatigue. You may be interested in this other article on Heat stroke in dogs: symptoms and treatment .
Has gastric distension and torsion
Abdominal distention or gastric dilatation is an abdominal inflammation that affects dogs and is the cause of vomiting in the form of foam or thick saliva. This is a symptom of one of the most serious gastric problems in dogs, since you have to act fast. The swelling of the belly originates due to a torsion in the dog’s stomach , which obstructs the circulation of both food and blood in this area and if hours or a day are allowed to pass, it can cause the death of the dog. Therefore, it is necessary to take him to the vet for an emergency operation .
This serious problem occurs mainly when a dog, especially if it has a wide abdominal region, such as large breeds, eats or drinks quickly and/or right after it jumps, runs or does some type of strong or prolonged exercise. Due to the horizontal posture of your body, the full stomach weighs and falls like a full bag that, if there is enough space in the abdomen, can swing and turn on itself, thus closing the passage and circulation both in the entrance and exit of the stomach.
Luckily, to notice if our furry suffers gastric torsion, we can look at several symptoms: the dog will be more restless, it will be difficult for him to vomit stomach contents or defecate, presence of cough, he will not allow you to touch his stomach and will present a constant drooling which may occur as a “vomit” of thick white saliva . We leave the word “vomit” in quotation marks because in this case it would be saliva, that is, we would only see white foam coming from the mouth and not from the stomach.

have bilious vomiting syndrome
Another cause of white vomit in dogs occurs when they suffer from biliary or bilious vomiting. This vomit can be clear and whitish or it can be completely yellow and occurs when the animal has had an empty stomach for a long time, too many acids and bile accumulate in it and, in the end, due to dizziness and stomach discomfort, it expels it in the form of vomit with white and yellow foam.

Has the rabies virus
When a dog vomits white foam easily, we think it may be rabies , since this disease causes excessive salivation. It is important to understand that vomiting in rabies occurs as the final stage of the disease, being preceded by other symptoms that are easily detectable, such as our dog becoming very aggressive or beginning to behave differently from those it usually has, for For example, when it comes to food.
However, today it is not very worrying in most countries because, if you visit the veterinarian frequently , this situation is easily avoidable, since rabies vaccines are usually administered to dogs. For you to know more about this disease, here we tell you How to know if your dog has rabies .

Why does my dog vomit white saliva and can’t breathe?
In this case, the dog may be suffering from what is known as tracheal collapse , a degenerative pathology that mainly affects small dogs and, above all, from the age of six. What happens is that all or some of the rings of the trachea have some deformity or flattening, which causes their obstruction, so the dog suffocates or chokes. The dog can have an outbreak in situations such as exposure to allergens and irritants, if the collar is used and the leash is squeezed or pulled causing the collar to press on the trachea, if it is obese, if it runs very fast, if it drinks very fast or even when upset, even if it is for emotion or joy.
When this happens, the dog has trouble breathing and, in the most severe cases, can have white foam and vomit and require veterinary attention so that they are administered bronchodilators so that they do not choke. However, in most cases, it goes away on its own, without treatment, by stopping what you were doing, for example removing the collar or preventing it from drinking at the time, also helping it to calm down and gently massaging the area of the throat.
