Barbaric dog-torture continues at the hands of cold-hearted Iditarod mushers.
Please help the dogs who are forced to run in the Iditarod dog sled race by
sending protest emails to race sponsors and promoters.

Here's a short list of what happens to the dogs during the race: death,
paralysis, penile frostbite, bleeding ulcers, broken bones, pneumonia, ruptured
discs, hypothermia, broken teeth, viral diseases, torn footpads and lung damage.

Stories about the dogs receiving top-notch health care don't square with the
facts. Dogs are often sick before the Iditarod starts but are made to race
anyway. While some sick dogs are dropped during the race, others are given
massive doses of antibiotics to keep them going.
