I live in Australia and last year our summer reached 44 degrees celcius which i believe is about 112 Fahrenheit. anyway I was working at the local vet at the time and everyday about 4-9 dogs would come in with heat stroke, out of this number on average 2/3 were sled dog breeds, eg huskies,malamutes and samoyeds. about 4 of those dogs died that week, whereas all the shorter haired and even golden retrievers with a longer (but very much thinner coat) pulled through. The vet said that it should be illegal for hotter climates to own sled dog breeds, as she sees so many die each summer, and it's not from negligent ownership, 99% of the time it is just due to heat stress, most are inside dogs, with airconditioning. but these dogs I suppose are used to Arctic climates, I wonder if we did this just thinking of ourselves and not the dogs. I am not in any way ridiculing owners of said breeds, just asking the question, as I'm not even sure where I stand.
