Today one of Sal's best play buddies (Diamond a 2yr old beagle/ACD mix) lunged at a guy on a bike and nipped him. My friend had her on a leash but was talking on the cell phone and didn't have her under complete control. The guy was really mad and cursed at my friend while he demanded her contact info which she gave. His "injury" was a scratch and didn't draw blood. How much trouble is she in? How much trouble is her dog in? What should she do?
