Just took a quiz and so far I've gotten what I'm looking for haha. GSP, Weimaranar, and Vizla, however they still say that they don't do so well alone and might be destructive. This poses a problem to me as I might have to leave for the work day, but I'd make sure they're well exercised before or after I return (or both).
I've heard greyhounds are too affectionate to be protective and that they are easily hurt on some trails. I don't know if it's true or not, but that's what I heard and I don't want to put the dog knowingly in any danger.
