Beautiful, Large Male Border Collie/Lab/Shepherd Cross

Beautiful, Large (105 lb) Male Dog looking for a new home. Charlie is a very good watch dog, but needs to be the only dog in the family. He does not have experience with other animals, but is used to having space. (Lives on an acreage now)
I have a complete bio on Charlie if you are interested. He MUST go to a good home where he will be given excellent care. References will be requested.
