When I was a teenager, I had a Labrador. She was a gentle dog, and I liked taking her for long walks. My brother named her Lilly & it really fit her. One day I was taking her to the park, and when we had been there for awhile, she bit a man who was standing close by. I don't know what made her bite his leg, but she did....and the man was obviously not thrilled...but after I apologed for the dog biting him, he just said he wasn't worried about it...and I remember being so surprised...I had told him that she had her shots and not to be concerned with that, and he believed me. So, he just walked away...boy was that embarrassing and totally surprising to me...I didn't think my dog would bite anyone!
