Embarrassed and Ashamed

I took my girls to the dog park here in Sugar Land day before yesterday. The days are getting warmer but the water at the park is still muddy. Oh well, the dogs sure don't care. It's usually a good time when we go to the park. I like the wind and they like the water. But Lucy can be an embarrassment when she is being the guard dog she so loves to be. On this day, when two bull mastiffs come running up and she starts her barking: they go in attack mode. Before I know it, she is on the ground and the other two are on top of her ready to tear her up by all appearances. I am so shocked and then I'm pissed. I've always heard not to intervene??? That's bull right? After yelling no a couple of times, the owner of the other two dogs comes up and is trying to pull his off Lucy. Then I proceed to start cussing and hitting the dogs with my "chuck it" while the owner is giving me a dirty look. He gets his dogs and Lucy gets up limping and whining. I'm still hot from her starting the scene while I look her over for injuries. By the time I come to my senses and look around the other guy and dogs have left the park. What was suppose to be fun and relaxing turns out to be an embarrassing day. I hate that I lost my cool and that Lucy just can't seem to socialize joyfully with the other dogs. She is always on guard it seems. When will "we" learn to control ourselves?

Sable is sooooo laid back and happy. I don't think I have ever heard her bark at another dog while at the park. Lucy did seem to act differently the remainder of our time at the park. Maybe the episode was just what she needed? I just don't know. When we left I was embarrassed and ashamed and they were just wet.
