Dog Renal Failure
Another reason for continuous vomiting can be that he has a renal affliction and could suffer dog renal failure. In such a case, do not hesitate and take him to your veterinarian which will give you the right diagnosis. Waiting or administering home remedies might make you lose the opportunity to correctly treat your dog. The solution here is not to stop the vomiting, like with a suppository; rather, the underlying disease must be cured.In general, you can say that an occasional vomit isn't alarming in a dog, and can be actually normal. But if he starts vomiting many times in one day, then it really is the veterinarian who should determine what he has and needs.
