A car chaser par excellence...
Years ago, before leash laws deprived dogs of their constitutional canine rights, our family had a collie that loved to chase cars. I guess cars must have been the closest things to sheep that Kelpie could find to round up, so she went after them pretty much every day, until the day when a car got the better of her. She came whimpering home, dragging her broken back leg behind her. A trip to the vet, a cast on the leg, and she was back, where everyone smothered her with affection as she limped around with her cast.
One would think that her car chasing days were over. Nope, she would limp up to the highway, and continued to chase cars despite the cast.
She never got hit again, and lived to a ripe old age (somewhere close to 20). Though she never learned her lesson not to chase cars anymore, she did learn one thing. For the rest of her life, whenever she wanted to get affection, she would start faking a limp as if she still had a cast on to get people to hug and pet her.
