The fact that sometimes a dog tears white foam,has its own explanation. This phenomenon in an animal is observed when, several hours after ingestion, the contents of the stomach are fully pushed further into the intestine, and it remains empty. In this case, it releases mucus, which helps protect its walls from eroding gastric juice. This substance (mucus) contains polysaccharides and proteins, which in the process of ingestion of air contribute to the formation of a mass with a cellular structure.
When a dog tears a white foam, it isevidence of the absence of severe symptoms with an empty stomach. A single such phenomenon does not require any treatment. In the event that the dog vomits white foam regularly, it is necessary to show the animal to the vet.
If an empty stomach happens to a dog like this, then thisindicates a disturbed process of separation of bile, which must enter the intestines after eating. In this case, the liver secretion of fluid in an animal occurs during a hungry hour. As a result of such a violation, irritation of the intestine proceeds, which provokes the transport of bile to the stomach. For this reason, the dog vomits white foam, after which the animal wakes up the desire to eat. This state is considered normal if it occurs no more than once in a week.
A similar condition in dogs caused by vomitingon an empty stomach, provides for treatment. It consists of the addition of food containing a large amount of fats to the diet, as well as feeding more often, but in smaller portions. Sometimes, when the dog breaks with white foam, there are used preparations of choleretic action, for example stigma of corn or Odeston. In the event that this condition becomes regular and is accompanied by a deterioration in the condition of the pet, the veterinarian should be consulted immediately.
It also happens that there is vomiting with blood in thedogs. Inclusions can have a different shade - from scarlet to brown and the color of coffee. First of all, with such a phenomenon it is necessary to inspect the mouth of the animal and make sure that there are no lesions on it. When a dog tears blood of scarlet color, it can be a signal of damage to the stomach or intestines, or rather - their upper parts (esophagus, pharynx). Also, this case may be a consequence of inflammation of the teeth and gums, tumors and trauma to the foreign body of the animal's mouth.
Particular attention should be paid to the area undertongue, because there can be found a loop of thread, swallowed incompletely (the dog could pick it up somewhere). At the other end, which is probably already inside the animal, there may be a foreign body scratching the walls of the stomach or provoking obstruction. Therefore, the pet and vomiting occurs with bloody patches. Among other things, the cause of this phenomenon in dogs can be gastritis in acute form, which is caused by the use of poor-quality food, as well as systemic pathological processes - hepatic or renal failure at the chronic stage, tumors in the intestine and stomach.
In any case, when vomiting masses of blood elements appear, the animal must be shown to the vet.
