P.R.I.D.E. stands for Providing Responsible Information on a Dog's Environment. You Don't Want to Keep. Obviously, this policy does not comport with the usual standards of animal care.
Dogs run to the end of their tethers and are jerked back by their chains.
There are many dogs who are old and deformed, but who nevertheless still enjoy life and continue to provide pleasure to their human companions. Old or deformed Iditarod dogs are put to death simply because they are no longer profitable to their owners. This drops even the pretense of humane and proper treatment of these dogs. If these dogs are unsuitable as pets, it is because of the mistreatment they received during their lives as sled dogs. Iditarod kennels acquire and breed many more dogs than can be used in the Iditarod race.
