Well I have noticed the other day that murphy would be heaving a little bit in the morning, even seems like he throws up in his mouth a little and then swallows it again. This morning it seemed even worse, he threw up a little in his crate. After he eats and gets out for a few minutes, he doesnt do it any more. This morning after he ate, he didnt drink much water. I had to hold it in front of him and splash my hand in it and he only drank a little bit. Other then that he behaves like the normal high energy dog that he is. His stools are normal, not runny or anything. I was waiting a couple days to see if it got any worse, and I am pretty sure I am going to take him to the vet soon unless someone can shine some light on it.
