Nope, as long as you don't covet his ass, you are golden.
Jim, Sam is very nice and friendly when I'm around.
Likes kids, especially little girls, kittens and other dogs.
That is his Alsatian side.
The Pyreneean side is a bit darker, he guards the truck and property fiercely when I'm not there, and will attack when told to.
I've had a couple of those dual personality dogs, and I like them very much.
Old Jack was ½ alsatian and ½ Riesen schnauzer.
That translated to a good buddy to everyone he knew and those I ok'ed and pretty much a direwolf to intruders or those who acted theatening.
Had it been him going after those two idiots, we could have gathered the pieces in a couple of plastic bags and left the rest for the crows.
One of my two best dogs, ever.
When he was still alive, I was doing a job in inner Copenhagen. Came in, as is my wont, at 6 in the morning to beat morning traffic and parked the truck and chipper, figuring I'd walk down the street looking for a parking spot.
As I stepped out of the truck, a guy came out of the building with a large Doberman on a leash.
When it saw me, it turned into a raving thing. Pretty much a set of teeth, with a dog attached.
I realized that the guy thought I was frightened of it, and was enjoying the hell out of the situation, so I turned around, opened the truck door, and told him: " If you want to plat that game, fine. But buddy, you are over matched!" Jack, Sam and Lev were sitting there, just waiting for me to say go.
He shortened up the leash, and walked away, without a word.
For me a dog is a good buddy, but also a protector of hearth and home.
