Sometimes vomiting is harmless when dogs have eaten too much too quickly. However, it is often an important symptom of the disease that should be clarified by the veterinarian. How to recognize that your dog is vomiting and when it is an alarm sign can be found here.
3 phases when dogs vomit
Before dogs actually vomit, this protective reflex is preceded by two phases. The first phase is that of nausea. Smacking, frequent swallowing, increased salivation, yawning and general restlessness can indicate that your dog is bad. Dogs also often eat a lot of grass when they feel sick to speed up vomiting and get rid of the nausea-causing disorder more quickly. You can then observe the second phase, the gagging. The abdominal muscles and the diaphragm pull together jerkily, while your dog keeps his mouth closed.
Finally there is the third phase, the actual vomiting. The muscle contractions and the closed mouth create a negative pressure in the chest cavity, so that the contents of the stomach are pushed up, get back into the mouth through the esophagus and can be spit out.
Vomiting can have harmless causes
If dogs eat too hastily, they vomit part of the food again. After that, however, they feel well again very quickly. If you change the food too abruptly for a varied dog diet, you can also provoke your dog's nausea. Dogs, like people, can also experience travel sickness when traveling in the car.
In these cases, the animals usually vomit a few times, but otherwise appear healthy and alert. Then watch your four-legged friend for 24 hours, provide him with sufficient water and only feed him with light food. If he does not have to vomit then you can rest assured that the vomiting was actually harmless.
Vomiting as a symptom of illness
If your four-legged friend vomits repeatedly in one day, if the sputum appears bloody or if the vomiting symptom is accompanied by other worrying signs, your dog must visit the veterinarian. Other symptoms include diarrhea, pain, loss of appetite, fatigue, weakness, difficulty breathing or fever. As a symptom of illness, vomiting occurs, for example, with inflammation of the digestive organs, infectious diseases, parasites and swallowed foreign bodies, which can lead to an intestinal obstruction. The life-threatening stomach rotation is often accompanied by vomiting or an attempt to do so.
It is also possible that your dog ate poison or that its food was spoiled. In addition, various organ problems such as hepatic insufficiency, renal insufficiency and Addison's disease can be behind the disease symptom. Cancer and ulcers are also an option. If the veterinarian is unable to determine a physical cause, psychological problems should also be considered as the cause of the vomiting.
