We adopted Mr. B when he was already 5 years old. We knew we needed an older, wiser pooch that could keep Miss M in check. Instead, we found Miss M keeping him in check:
We joke that Mr. B was an unsocialized only child, because he doesn't quite understand the concepts of toys and play. He is constantly hoarding his toys and keeping his collection stored in his tepee.
And even with Miss M constantly sticking toys in his face, he won't take the lure and he just stands there. We originally thought this video was funny because Miss M was being so bratty, but looking at it under this perspective, we find it funny that Mr. B doesn't understand the concept of play and is more willing to stand there, and be used as a table, than take Miss M's bait.
I wonder if dogs like Mr. B don't like to play because of lack of socialization? Or is it really just a personality thing?
