Audrey, thanks for thinking of me! I don't think he's border collie although he may have some in him. (His ears and his activity level! ) He has brown feathered legs and feet, like rottweiler coloring, although I don't think he has rottweiler in him...I was looking at his feet just this morning! They are huge!!, webbed and he has hair between his toes. Sometimes I think he's one kind and then I think no, he's this...and then no, he can't be, he must be this kind...It's a complete mystery I wish I knew...
