Recently I have noticed that Roxy seems to have problems eating. I noticed that sometimes she coughs after she eats food. (not all the time) Once, food fell out of her mouth while she was eating. A few times, it looked like she was trying to throw up. She was hunched over, lifted her belly and exhaled multiple times. I checked her teeth and they look aligned and normal... she still eats and drinks a lot and has a normal appitite. What is causing this? Any ideas?
