Chad was led into the metal kennel building. The smell of bitches was driving Chad crazy. He had been an oversexed horny teenage boy before, but now he was a stud dog surrounded by two dozen bitches in heat. He pulled at his leash, as he charged forward toward the yelping bitches. Todd laughed, as he started to half run as the powerful boy headed dog led him toward the breeding pens. Chad started to yelp as he raced to his future mates.
Todd released the leash, and shouted, "I gotta open the pens, Chad."
YELP!
Chad's dog body stood upright pressed against the chain link gate to the first breeding pen. His fore paws hung over the top metal pipe frame. His hind paws rested on the metal pipe at the bottom of the frame. Todd walked over and unlocked the pen gate with his key. He lifted the latch to open the gate, and then he looked. Chad had mounted the bitch in the pen through an opening in the chain link, and was now knotted to a bitch named Daisy. Todd swung the gate with Chad mounted on it, and to Daisy, who backed out of the pen with the swinging gate. Todd laughed.
He walked away, most knots lasted 20 minutes, so he had time for a beer. Chad would probably take longer.
