Sometimes Loki eats grass and it seems that he only does it to induce vomiting because he pukes every times he does. He doesn't eat grass that often but he seeks it out sometimes and gobbles the grass up. Now sometimes he just eats the grass and barfs up some mucusy stuff and the grass, and thats that. But sometimes he eats the grass and starts pacing and heaving, (gulping real heavy,) before he throws up. When he does that he pukes and then falls over on his side! I think that he gets light headed from the pacing and gulping of air and vomiting. He has done this twice before, most recently yesterday. He always gets right back up, nub wagging, and normal...or else he gets up and tries to eat more grass. I just don't understand why he does this at all. Why does he eat grass and throw up? And why does he fall over sometimes? My vet said not to worry that he probably just gets dizzy from pacing and heaving. BUT OF COURSE IM STILL WORRIED! Loki is almost 4 y.o, and otherwise healthy. He still eats & drinks normally through these episodes....I don't get it. Any advice/help is very much appreciated! Thanks guys!
