I don't trust a lot of that info (peta, hsus, and the fact that glacier brought up, Helpsleddogs has no experience with this sort of thing).

No matter what you do there is always a chance. Weather people or pets die of natural causes, accidents or on purpose, there is ALWAYS a chance of death no matter what you do, really. People accidently fall down the stair & die, people get in car accidents & die, the list goes on & on & on. I personally would rather die doing something I enjoy.

Have you ever seen a sled dog when they get ready to go? They are HAPPY! They LOVE doing it.
