I would have done MUCH more than write you a nasty letter!

Wilbur is HORRIBLE with large dogs. He is always on a leash. If a large off leash dog ran over to him I would have to get it away. I HATE IT when people have their dogs offleash at the park near our house, because I can't feel confident that they won't decide to come "Play" with Wilbur.

You were the one in the wrong in this situation. If your dogs can't be trusted not to interact with other dogs who might not be very friendly then they SHOULD NOT be offleash. Please be considerate of others and walk your dogs on leash.
