There are many reasons for dogs to vomit. You should first check whether they have been vaccinated and whether they have been dewormed recently. If there is no vaccination, you must suspect the possibility of canine distemper and parvovirus infection. If there is no history of deworming, you need to suspect the occurrence of parasitic infection. At the same time, esophagitis or digestive system inflammation caused by various reasons are possible. Can cause vomiting. Finally, vomiting caused by poisoning or other causes should be ruled out.
