It's all preferences... You like action movies or comedies or fantasies? Or maybe a little of each?
You know me... I love shepherds too. And I've been mostly taking in stray mutts of late ;~D
I'm not as open-minded as you. I think I "make a decision" and stick w/it, hard. Like my love for GS (K9 Corps demos), and my relative dislike for Goldens (seeing too many goofy 1s who can't be good guard dogs as pets; my view is dogs should be ~minimally~ useful since even the best 1s cause some inconvenience like ~having~ to be home to let them potty). Of course there are lots out there I think would be neat, and others I think I couldn't care less about, tho I don't know much about their personalities or other issues.
Movies? I like alot; if anything it's "drama" I tend "not" to like (not always, of course). I like all kinds from the truly classic eras, esp. musicals and comedies as a whole. ;-) I'm versatile - hey, another reason I love GS!
You're right it's all preferences. 1 of my biases on dogs is ears - I much, much, much prefer natural prick ears. "Natural" meaning, find me 1 animal in the real wild world that has drop ears. Prick ears look alert and intelligent. The latter meaning alot to me (and probably why I was always willing to like all cats)! :D
