Humane mushing does have a voice - however, industry mushers in North America choose to not to hear it. Overseas, there are major advances in sled dog welfare and animal welfare in general.

ie: Mushers in Finland are working with the International Institute of Animal Ethics, and inquired about using the Sled Dogs documentary at a mushing conference, using it as a lever to having a keynote talk on responsible welfare and out of date standards. 

The World Sleddog Association states, “Unfortunately, in some countries it is permitted to keep dogs on chains. Nevertheless, this practice should be rejected by all sled dog organizations nationally and internationally. Sled dog organizations should engage with mushers practicing this with the aim to abolish this practice.” WSA member clubs follow this rule.

There are those of us who are working toward a humane sport. Many past, accepted cruelties and neglectful practices are no longer being swept under the rug. Mushers will need to adapt.
