Tiny, who wasn't tiny, was a solid dog.
We never hit her, but we did wrestle with her.
She was a very physical dog, loved to wrestle around.
She did get stepped on, and accidentally clopped in the chops with shoes because she liked to be 'right there' when you walked along.
Of course, we'd stop short, and give her scritches while asking her if she was okay.
The dog would look at us like we'd gone nuts and pretty much go, "Yeah I'm okay, why are you people acting crazy?"
Dogs are pretty incredible creatures. I also like their sixth sense. Sometimes they know when something is going to happen before anyone else does. I've heard they can sense earthquakes, although mine didn't when we had one here.
And they say once they smell someone, they never forget the scent. Their sense of smell is so many magnitudes greater than ours.
