Maze gets a cough/wheezing after exercise. At first I thought it was allergies since she does have them, then I thought smoker's cough since I do live in a house with smokers (I'm the only non smoker) but the only time she does it, is after hard exercise.
Usually when I hear it, I make her rest for a few minutes and let her catch her breath. I don't let her run hard for long periods of time. Normally when we're playing fetch, it's only for 20 minutes. Everything else is normal and I'm not to worried about it. Just curious. Of course if it gets worse or anything, I will take her in to the vet.
