I’m just throwing this out because it’s something I’ve noticed with male dogs.
Everyone I know with a male dog has had their dog neutered. There’s a marked (no pun intended) difference in the temperament of the dogs who, even after neutering, continue to exhibit leg lifting, or “marking,” behavior. Not indoors or anything like that, but I’m talking dogs that on walks, etc., that continue to pee on mailboxes, posts…anything “markable.”
The ones I know that keep leg lifting are much more assertive.
I myself have an 8mth neutered male who has never been anything but the non-dominant, “I love everyone” type.
My sister’s 10yo rescue she’s had for 8+yrs is the same way; never lifted his leg on anything. I would trust him with anyone.
Another acquaintances 3yo golden is the same - squats to pee and the kindest beast on 4 legs.
The couple neutered males I know of who continue to be the marking type, while “nice” dogs, do have a bit of dominance in their personality.
So just asking:
Among NEUTERED male dogs:
Do you see different behavioral/temperament traits between dogs who continue to lift their leg, and those who don’t?
