WE sadly lost our girl Sadie to bone cancer earlier this year She and her littermate Dozer have been togrether For almost 8 years and Dozer is clearly missing her. HE is very needy and gets upset when we leave him home alone. WE think he needs new friend, Dozer is 8 years old tomorrow and weighs 150lbs (not fat) he is Big and spoiled. We are thinking we should get a female adult dog we don't want to deal with anotheR puppy. Anyone else have some experience?
