In the last several days Ecko will be fine all day. Eats his breakfast takes his morning walk and he's fine. I come home, feed him dinner we chill on the couch and about 9pm he ralphs on the couch. It's about half his dinner that he's tossing back up. Then he's fine again. I can't get to the vet until Tuesday. So I'm hopping someone here might have an idea. Any comments or advice will be appreciated.
