There are three common reactions after a dog has taken deworming medication. The first is the no reaction type, which is a relatively healthy dog with good gastrointestinal function. The second type is no spirit type, this is the reaction of most dogs after eating deworming medicine, which is also relatively normal. The third type is the violent pulling and vomiting type, the drug will react very much. Some dogs have weaker stomachs or are older, so they will react more to the medication and will pull and vomit, or even dry vomit. Generally this is not a particularly big problem, as long as the effect of the drug will slowly improve the symptoms. Once more than 24 hours still symptoms have not been reduced, we must send to the vet for examination.
