My Collie dominant Sheltie (45 lbs.) ran in front of a car at about 40 miles an hour. His left shoulder and leg were struck and he rolled about 5 times into my driveway. He cried for a moment, but stopped on my approach. He holds the left (ankle) bent, but is trying to put it down. He balks going upstairs. Otherwise he would like to be very playful. Appetite and systems are fine.I .would hate to think the leg is broken, not sprained and bruised.
