Our dog threw up moss on Tuesday and today he is twitching like muscle spasms. He also is only eating dinner (vs. two meals a day). I don't know if he ate anything else. Otherwise, his behavior seems normal. He is playing with our other dog and when he eats dinner, he seems normal. He seems happy with tail wagging. Any ideas on what could be the problem?
