More: Jack was 4 1/2 months old, in a kill shelter when taken in by A. D. O. P. T.. We were the lucky ones to get him. He loves to terrorize his toys; food, esp chicken and steak; naps, he has 9 beds and walks, waters every tree, leaf and bush . Jack's started agility around 8 yrs old, just for fun. He injured his neck and needed life saving surgery and 3 months total rest. A couple months later, at age 10 he started Nose Work and loves it. He has won some ribbons and we are so proud of him. He's still going strong for being a senior citizen.
