More: We adopted Yogi from Bullmastiff Rescue when he was 15 months old. He was a mess with bleeding fungus all over his body, a parasite in his intestine and no training how to walk on a leash or control his impulses. The first two years, when I would walk him, I would become the Flying Nun breaking 6 of my bones, cracking ribs, spraining ankles and wrists over two years. Now he's a really good boy at 130 pounds, it was worth adopting him.
