Boo was a fighter from the beginning. Major hernia, leg bone deformity requiring surgery, radiation treatment and chemo treatment. She was the Princess of the house and was a very smart lady. A Rottweiler/Tibetan Mastiff mix, she was the runt of the litter, her brother Gizmo was the food hog of the litter. We got both of them and our daughter got another sister. They have brought a lot of love to our family and Boo will be missed. Gizmo still looks for Boo when we come home from shopping.
