So sorry for your loss!! When I had to put down my s**tztu after 17 years I had my brother do it cause i couldn't handle it so i understand and you and your mom are in my prayers and thoughts!!!They do become a big part of a family after all that time and you take the time you need to grieve....Hugs and Kisses!! But know that he is on Rainbow Bridge having a ball with all his new pals!!!
