Strange internal cough/hacking.
My new doggy Annie just finished her kennel cough meds and I have seen a huge improvement in her personality, she is actually energetic now! But I have noticed that every so often (6-7 times a day) she does this strange internal hacking thing. She will be laying down then all of a sudden she will bolt up and start, I guess the best way I could think to describe it is like an internal sneeze, or like she's choking on something, but then it stopped after a few coughs . It started about 5 days ago and I have no idea what it is or what to do about it.
