Spot on Huggers . Ive never had a problem walking dog round Peckham Rye Common, off lead, for eight years. Ive probably been lucky. He is very playful and approaches most dogs, but if one snaps or growls, he will then leave it alone . So he does know some are not to be messed with. This was unfortunate but he will be ok , thanks to that guy. I will be much more wary in future .
