No! the dog didn't save my life...
She is getting older but still very aware of everything outdoors at all times. I think sleeps with one eye open at all times, that is what Border Collie"s do.
She is gonna be 12 and and still gets up to 3, 1 hour walks per day and then even more extensive running, chasing a frisbee..
Great dogs but you have to be willing to be trained by them.
