Three-legged dog with cancer saves baby otter in Minnesota river drama

Otter would likely not have survived without intervention of goldendoodle Gus, officials say

A rescue of a drowning baby otter from a near-freezing river in Minnesota was remarkable not only for the successful outcome but for the identity of the rescuer - a tiny three-legged dog waging its own battle for survival with cancer.

Wildlife officials said the otter would likely not have survived without the intervention of Gus, a six-year-old goldendoodle that had one of its back legs amputated earlier this year because of tumors.
