More: Trooper was a very intelligent dog and lived to be 15 years old. I've had many goldens my whole life but he was by far the smartest and very loyal to his family. He brought many smiles to my face when I was going through hard times as life can bring. He survived a broken front leg and when his stomach twisted (bloat). His will to live shows the life we gave him through his 15 years. RIP trooper.
