At first i was worried that Maybe might have a collapsed trachea. took her the vet. and came home knowing no more than before we went. Now it could just be reverse sneezing? At leas i'm hopeing thats what it is and that i have nothing to worry about. She has had her odd cough on a few occasions. sometimes after drinking sometimes at random and twice she had really bad episodes after pulling the dog sled with my other two-to me it seemed to last several mins. but i was pretty worried so it probably seemed long than it was. I have read that drinking, pulling on lead and excitement can cause reverse sneezing, so pulling a sled could probably do it. If it is reverse sneezing is this nothing to worry about? Or can reverse sneezing even be something to worry over. I have no problem not having her pull the sled. However i would love for her to be able to, because she loves running and pulling and it's becasue of her that i have grown to be obsessed with huskies and sledding.
