As with humans, dog vomiting is usually a symptom of an underlying condition. This may include flu or infection or something even more disconcerting. While most cases are the result of your dog eating something that doesn’t agree with him, prolonged vomiting can lead to dehydration or intestinal obstruction; in fact, left untreated, vomiting can be life threatening to your dog and as such should be taken very seriously. Dogs will put almost anything in their mouth and if they ingest it, this could lead to throwing up. Still, you should always make sure to keep a watchful eye on a dog that’s throwing up.
Gastritis is the main factor behind vomiting and this can be caused in a number of ways. As mentioned, ingesting an unfamiliar food or non-food item can cause the stomach lining to become inflamed resulting in vomiting. Moreover, dog vomiting may be the result of a bacterial or viral infection. In such cases, some antibiotic or antiviral medication will likely need to be prescribed by your veterinarian. Another common factor that causes dogs to throw up is excess stomach acid or bile. If you see that your dog is vomiting a yellowish brown fluid (often just before meals), this suggests that there is excess bile or stomach acid causing the vomiting. Excess bile or acids is the result of having an empty stomach so the solution is quite simple: Feed your dog more frequent, smaller meals to prevent the build up of digestive fluids.
Likewise, unfamiliar foods can cause your dog to throw up. Imagine you eat a new cuisine that you’ve never tried before. This experience often causes human stomachs to become upset and unfortunately for dogs this often results in throwing up. Suddenly changing your dog’s diet may be the factor causing the vomiting so reverting to his old diet will likely clear up the problem. Introduce new foods gradually so your dog can adapt.
