| HI, I found the answer to this, at least in part. I have been informed by my last vet that this symptom is most likely to be heart related. In my pooch's case, it was allergy induced. The allergic reaction is acompanied by an acceleration or irregularity of the heart rate, this in turn, induced the cough (body's natural mechanism to regulate heart rate) that ultimately culminated in an extreme arritmia and perhaps a convulsion (after further acceleration of the heart due to excitement) that knocked her out. Interesting huh? |
