ANCHORAGE, Alaska (AP) — Sled dog mushers in communities on the Yukon River have received thousands of pounds of donated food to help feed their animals during a shortage of the salmon that is normally a staple of their diet. The Anchorage Daily News reported that pet food manufacturer Purina donated 39,000 pounds of high-protein dog food last week to mushers in Tanana and Fort Yukon. Yukon River Inter-Tribal Fish Commission Director Stephanie Quinn-Davidson helped organize an online effort to help the mushers after several contacted the commission. The campaign raised more than $32,000 in addition to the donation from Purina.
