I got a foster dog around 2 months ago, and within 24 hours she had come down with kennel cough (the rescue were very apologetic, but they were not to know, and some of the other rescues came down simultaneously). As we do not board ours, they had not had the vaccine. Storm got it around 7 days later, and Holly after 9 days. It hit our foster quite hard, as she was already low from being abandoned and being in the pound which she got on badly with. We used CHILDRENS BENYLIN FOR CHESTY COUGHS (comes in a red box) as advised by the rescue. It should be the children's one as the adult one has alcohol I believe, and for chesty coughs, as the dry cough version suppresses the cough, which is not what is desired. Our foster got it quite badly went on antibiotics for 5 days, which put her on the mend, but she had it for a full 2 weeks. We were ready with the BENYLIN when ours got it, and both got it very mildly, so did not require more than just BENYLIN. There was a lot of hacking coughing, gagging, but also sneezing like in the video. While they were coughing or had any symptoms, I did not go in the park, but rather just walked the streets. As bad as our foster was, she refused to miss a single walk.
KC was around the neighbourhood at the time mine got it, and most people whose dogs got it did not need anything more than BENYLIN - it is the canine version of the cold, but it is VERY infectious, which is why I made no effort to segregate my dogs, as I knew they would come down with it anyhow.
Hopefully a few more days will see an improvement in your Husky. It is common, but in most dogs were there are no underlying problems, the dog will get over it in the same way as a cold passes
