Thanks everyone for all your input. I would be in heaven if I could rescue a Greyhound - my only concern is the slightness of the Greyhound vs. my big Berner's frame. Bodi plays very respectfully with all dogs, however, graceful he is not. A Berner colliding with a Greyhound may lead to an injury....to the Greyhound.
As for Goldens, LOVE them! I thought however, that they were a little on the clingy side. The size, temperment and bone structure is a great match though. I will definitely look into an older rescue.
....and Leo's are awesomely gorgeous. They remind me a lot of Berners. Leo's I thought are very wary of strangers and protective of their family - is that true?? ...and don't they drool??
Amstaff's and other similar breeds unfortunately are prohibited in my township - UGHHHH! Pitties, Bullies etc. are probably my second favorite breeds. I truly adore American Bulldogs.
