He is an Australian shepherd dog who navigates the world with fearless joy. When I had two heart attacks, his unwavering devotion helped save me

Luke, a blind Australian shepherd, came to us seven years ago, after we rescued him from a working horse farm. Even though he can’t see, Luke moves around with a fearlessness that is inspiring.

He compensates with his other senses; Luke can smell and hear at an astonishing level, that’s how he notices things. But he also seems to understand that he’s going to run into things and be confused at times. That does not deter him in the slightest.
