Roxy and Lucy

We've been going to that park for over 4 years and we've met dozens of dogs, but tonight, a dog that seemed friendly at first, suddenly attacked Roxy. I was shocked, but even more so by how quickly Lucy got the better of Roxy - I thought she would win a fight. She got a cut under her ear, and a few scratches - nothing major. She was more upset by my yelling, though I was yelling at Lucy, not her. I thought Lucy's owner could have been a lot more apologetic! Maybe he was distracted by concerns about a lawsuit, as well he should!
