My grandchildren (at the time, they were 2,3,4 yrs.) would always kick my little toy poodle when they came over - I think small children think this is their best, safest line of defense, even if there is nothing but a 'perceived' danger in their little heads. As soon as they felt the least bit of fright, out came the foot. I can't tell you how many times I had my back turned, heard my dog squeal, and realized the dirty deed had been done-I could always tell by the guilt written all over them. I never spanked my grandchildren for that, but I did buy a gate and put my little dog behind it every time they came over. Problem solved, but in your case, you'll have to think of something a little more creative than that!
