I was thinking, John, I was lucky to have never experienced a stranger-adverse dog (Deb doesn't want the responsibility of a dog this late in our life, and my first wife & I had cats), but then I remembered my parents' dog, Rosie. The first two family dogs grew up with little kids, either my sister & I (Susie joined the family when we were barely in school) or the neighborhood kids (who would show up at my parents' door and ask my mother, "Can Daisy come out and play?" and then run her into the ground until she came back in, panting and happy), but Rosie grew up in a childless house in a childless neighborhood.

And then the grandkids (my sister's kids) showed up.

Life became chaos. Rosie got yelled at for eating the kids' food ("But it was right at her height!"), for growling at the kids ("Honey, the dog's supper dish is not a toy!"), for getting hyper when they would shriek or cry ("Sorry, Rosie isn't used to noise!"). The arrival of the grandkids meant misery, because inevitably Rosie would be put in her cage while Those Children were allowed total reign of HER HOME.

Fortunately (?) Rosie became deaf in the next year, and visits were no longer traumatic. For anybody.
