There is a HUGE difference between a kid jumping on a dog from two steps up and stepping up on it. You can prove this for yourself. Lay on the floor and have a kid step up on your stomach and stand there...then have the same kid jump on your stomach from two steps up. You’ll see what I mean.
The dogs are clearly able to move away if they are uncomfortable.
Anybody who thinks these pictures show anything other than the special relationship between kids and dogs - particularly a dog’s loving patience with “their” kids - doesn’t know much about kids and dogs...especially dogs.
I realize the dog will move out of the way if it can. I wouldn't lie on the floor and let a kid step on me anywhere at my age. I have to tense up my mid section when my cat walks on my ribs and wants to be petted in the morning. After he eats.
