Too friendly for her own good

Many people I have met while walking Janet have described her as "like a lamb", "cute" and/or "not a mean bone in her body". Janet is indeed cute, soft, white and very friendly. And I have always feared that she is sometimes too friendly for her own good. She would even approach a cayote if she sees one even if that cayote would mean to eat her. My fear was confirmed this morning as we were walking. We met one of the neighborhood guy walking two big dogs. One brown dog that was friendly and another black dog that was not too friendly. So Janet of course was pulling towards the dogs to meet them. As we have the dog interact, the neighborhood guy was cautious with having the black dog interact with Janet. It was all ok cause they were just sniffing each other and the big black dog was not barking or growling or showing signs of aggression. As we separate the dogs to get on our way, the big black dog just snapped and bit Janet on her left hip/thigh area. Janet of course let out a big yelp and the big black dog bite did not hold long. Janet received one bite that penetrated her skin but she seems ok. She was shaken but not limping or showing signs of pain or bleeding. When we got home, I softly washed the wound with water and this obviously stung a lot cause Janet yelped so much from the pain. Poor thing. Her suffering was eased with a big treat which she gingerly ate. If she was not in pain she would have eaten the big treat voraciously. I think she will be ok. I have had dogs before that fought and leave each other bloodied and they were able to heal. I just hope she learned something from this experience and not be too eager to meet every dog we see. I definitely have learned to be selective on who she can met or not next time.
