My old bosses have one named Pepe.
He's cute, but he's... a bit unstable, IMO. He's great with their family but he's not great with strangers. Plus some potentially dangerous quirks - if I came to work and I had handled my ferrets that day, he would follow me around the store and snap at me, continuously.
Not even aggressively, just... excitedly? I guess his prey drive was turned on but he knew I was human. His teeth caught me several times, bad enough to leave scars for awhile.
I think a lot of his behaviours might be attributed to his going to the stores all the time and not really being a social dog, and not really getting any positive associations with social behaviours (always reprimanded for going anywhere near people). He's my only real experience with GS.
