I have a 9 week old beagle that is acting sick about every 2 or 3 days, he eats good for a while then he stops eating and acts sick. His stomach growns a lot during this time and his stool is loose and today he has been throwing up. He picks at his food and then he spits it out and or burries it. I don't know if maybe I should change his food or try something else. I have called the vet and he has not called back yet I am deperate he is like a child to me and I hate to see him sick. Please help.. :confused: :(
