Slightly off topic, but cute story, was
our late dog Toby, always wanted to be a cop.
That was our joke about him. When the kids were teens and would wrestle, Toby watched closely and intervened now and then if Toby felt it was getting out of hand.
Once some boy was tickling my daughter too hard, and she started to scream about it, and Toby lightly nipped that boy. I felt the dog was correct.

lotsa lil stories like that, okay.
Toby was very very unbiased in his judgement, he never hesitated to intervene, even if it was his own master, Toby would get in there and give you a look, or even show a growl, a lip lift, or 1 light nip in extreme situations.. "settle down here!"
so once, the toddler fell over and was screaming his head off, so i picked him up, and was holding him, leaning over the toddler, had him all folded into my arms, rocking him.
and i realized, Toby was watching ME closely, and kinda glaring, very very slightly lifting up one lip, and i realized-------Toby thinks *i* am hurting the toddler!!!

and Toby was signalling that he wanted me to stop hurting the toddler!! I suddenly realized how this looks
to a dog-------big person holding small person, and small person is screaming. (Toby wasn't much
yet used to crying and screaming from kids, not yet, it was all still new to him. Toby found kids screaming alarming back then.

)
so i had to 'tell' Toby, it was all fine, that yes, this lil person IS screaming and hurt, but, i'm
comforting the toddler,
not hurting the toddler! Hard to explain how i "told" that to my dog,
but, i did!!

I talked calmly to Toby, and petted him, and talked to him, and he sat down and relaxed, even though the child was still crying loudly. Toby did learn that kids scream and cry sometimes, and stopped getting so worried whenever they did.
i was amazed, that Toby, who once disliked that toddler, was now protective of the toddler!!
