OMG! First of all, what kind of person just let's their little kid (2-4?!) walk up to a rot with NO ONE around? Ok, some rots are mean, others are so gentle. WHY would you let your little kid just go up to touch it without asking first-DUH!
Second, what a BRATTY little kid! He kicked you in the shin?! What a brat! Kids aren't the same anymore. They are disrespectful little brats (I shouldn't say that, but many of them are. Their parents don't teach them respect anymore).
I would NEVER let my kids touch a dog like that. A Yorkie, maybe. But even then, I would probalby still ask because you just don't know. A rot or doberman, no.
You would think that with all of the dog bites that are in the news today people would be a little bit more careful.
