How badly is Scooter hurt? Have you talked to his owners?

Next time just don't let your dog out freely, period...you can never know what could happen...your dog could have ran out into the road after another dog and be hit by a car too. I know he was just on the porch, but he bolted so quickly, so I'm sure it was hard to control him. Hopefully Scooter's owners will not let him run loose either.
