You may not like or agree with the reasoning for the rule, but the dogs are safer because of the rules.  Fewer dogs are dying and have less injuries (I'm a dog drop volunteer).  If a dog is running to the trailer--which has to be a miserable, bumpy ride--it isn't because he or she equates it with a couch.  It is because he or she is exhausted and does not want to run.  The original run was done as a relay with something like 150 dogs, and even then, several died.  We have turned an emergency run into a race for personal glory that results in dogs that are overbred, unwanted and useless if they do not want to pull or get injured, and often have fatal injuries.  I know there are many of you who sincerely believe the dogs love to run.  I have had huskies.  There is a huge difference between running several miles, and being forced to run a thousand miles and live on a chain in the elements the rest of the time.  If you lived on a chain, you would be excited to run, too.
