You eat too fast or too much
This is one of the most common causes for a dog to vomit white foam. If you have observed that it seems that your dog is not well and seeing his symptoms you have thought something like “my dog vomits white drool” or “my dog vomits transparent drool”, it is very likely that it has drunk or eaten too fast. Normally, if the vomit is like transparent drool, it will be that it has taken a lot of water at once, has choked and has expelled it, so it is water and slobber. 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 rest of food, even whole or little chewed.
It happens in the same way if at the time of serving your food we exceed the portion served, thinking that he will eat rationed by himself, but on many occasions dogs eat until the plate is empty, which causes their diet to be altered.
When vomiting and gagging are continuous, it may mean that something has been obstructed in the dog’s tract or that it is another problem or disease. If this occurs, it is best to contact a veterinarian immediately.

You exercise too much
As it happens to us, carry out too much exercise can lead to vomiting in dogs. The reasons for this are due to the fact that, by eliminating too much water when running, they become dehydrated, in addition to the fact that they have also been breathing forcefully, the latter contributing to nausea in dogs.
It is important to exercise with your dog in a controlled manner, making sure not to exceed his resistance and providing him with a source of water whenever he feels thirsty. If you do not monitor this situation, your dog may receive a heat stroke or fainting due to fatigue. In this other article we give you some tips so you can learn how to prevent heat stroke in dogs.

Has gastric torsion and distention
Abdominal distention or gastric dilation is an abdominal inflammation that affects dogs and causes 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. Belly swelling is caused by a twisting in the dog’s stomach, which obstructs the circulation of both food and blood in this area and if hours or one day are allowed to pass, it can cause the death of the dog. Therefore, it is necessary 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 fast and / or immediately starts jumping, running or doing some type of strong or prolonged exercise. Due to the horizontal posture of your body, a 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 dog suffers gastric torsion, we can look at several symptoms: the dog will be more restless, it will be difficult for him to vomit stomach content or defecate, presence of cough, it will not allow you to touch his stomach and will present a constant drooling which can occur as a “vomit” of thick white saliva.
