Oscar is well behaved off lead. His recall is good and he won't approach without permission. I do admit that with other dogs, he is extremely playful, although when I call him away, he will come instantly. I never know what to do when I see another dog, especially if they are on a lead, coming in our direction. Do I attach Oscar's lead or not? I call him to heel, until the other owner gives me the nod. I did go through a stage of putting him on the lead but wouldn't want to offend another dog owner by suggesting I am afraid of their dog. Oscar is a toy poodle and has a penchant for the much bigger dogs. What do you do?
