I have a son like that Havoc, if there is any dog poo about his size 10's will find it. He came home from school the other week and there was so much dog poo caked on the bottom of his shoe I don't know how on earth he managed to walk properly :-( - but he pretended he didn't even know it was there.
We have part of our garden fenced off for a play area with swings, slide, sand pit etc and have a gate on to keep the dog out. We did this when we used to have a German Shepherd because he used to charge down the garden to see who was passing the front gate and if my daughter got in his way he would have knocked her over in his hurry. He did try to sneak in though if the gate was left open especially if we were sunbathing in there and he was on the other side of the fence, he hated that.
