That was funny.
I owned labs and loved them. GS, but I was afraid he would hurt someone and had to find a home in the country for him. He was an alpha male. I would pet any lab and most GS on sight. I like pit bulls, but I would never pet one unless the owner told me it was ok. Probably should not anyway, but I just like them too much. As for little yapping dogs, let me just say I have learned to keep my hands to myself.😉
I’ve actually liked many small dogs. Including my sisters, who has mostly been owned by her son (RIP). Some of course have been scary, others just annoying.
Don’t conflate “alpha” with vicious or unreliable. My bestest dog ever, my first pedigree GS, was very much dominant, but docile and joyous. She was bold and would assert herself, but only once did she ever even look vicious (she’s had multiple opportunities both people and dogs) - when my sisters young GS tried to mount her in our yard. Oh, she turned on him so fast and drove him clear across the yard for daring. Snarling and teeth everywhere. He got the message and she stopped.
She was a very stable, solid dog who was fully trustworthy and could handle herself excellently. I was proud of her. Proud. (How many people say that about their dog?)
Anyway, dominant does not mean aggressive. Assertive, definitely, but not aggressive.
