I have a 7 month old pug named Toby. He eats everything. About a week ago he started vomiting. He did this for a day and the second day had what I think was a seisure. he continues to throw up every day or every two r three days. He does not act like he feels bad, he is eating and drinking and playing as usual. I have a cat and he eats her poop. What could be causing him to vomit so much? Can I sotp him from eating everything? PS he has been vacinated
