I see this as much more than a sled dog issue. It's a dog issue. There are many dogs who are kept chained up outside all the time, through harsh winters, without shelter, or adequate food and water. I've seen this type of "animal care" across the north, and in more southerly regions as well; it certainly isn't restricted to sled dogs.
How many people will welcome a dog into their house when he/she is young and "cute", only to neglect the animal as an adult?
