I'm not really sure what to do. It started Saturday, he wouldn't eat until about 10:00 p.m. then throughout the night he was up vomitting. He layed around and slept most of the day Sunday, finally eating around 4:00 p.m. and once again he was up most of the night vomitting. He normally eats Iams, but I started giving him Natural Choice for sensitive stomachs and he did great. I think I narrowed it down to the treats and he hasn't had anymore and his appetite is pretty much back to normal. However now he is constantly having to clear his throat and making motions like he has to vomit but doesn't. He has also started sneezing a little bit and he is still not sleeping at night (which means I'm not either because I'm up worried and constantly checking on him) then he sleeps most of the day and just isn't his normal playful self. Does he have the "doggie flu", any suggestions?
