Sam and Dean continued to scratch at the door until a person in a neighboring room called the manager and he unlocked the door.
"What is going on in here?" His tone demanded an answer.
With the door partially open, the Winchesters were able to slip through the door and bound down the hallway before the manager noticed them.
He chased them to the front door of the motel, where, lucky for them, a guest entered and they were able to escape.
Bobby was close to the motel when two dogs shot across the road just a few yards in front of his car. He had to slam on the brakes.
His eyes widened as he watched them continue on their way and disappear behind a house. He recognized those two dogs.
"Dammit boys," Bobby groaned.
He parked his car on the side of the road and took off after them on foot. Once he was behind the house he got a visual on them and was able to keep them in his sights as they made their way to the most populated part of town.
Dean and Sam moved with purpose. They sensed something normal people couldn't sense but all animals could - the power of a witch. It was luring them somewhere unbeknownst to them.
Bobby was able to just barely keep close enough to Sam and Dean to keep track of them. He wondered where they were going, but had a feeling it may have something to do with Dr. Hart.
Seven minutes had passed before they reached a parking lot in front of the hospital.
All the dogs were there and Dr. Hart was standing before them.
Sam and Dean sat down at the back of the pack.
"You all came from wolves," Dr. Hart said. "Time to do what you were created to do. Run free. Hunt and kill."
The dogs howled and scattered into small groups of three to five, ready to kill. They left the parking lot headed in different directions.
Sam and Dean were the only two dogs left.
"Go!" Dr. Hart ordered them.
They stood and growled at him, their hair raised.
Dr. Hart's eyes widened and he bolted into the hospital. The brothers took chase through the automatic doors and Bobby followed them.
Dr. Hart tried to make it into an elevator but Dean cut him off and jumped, nearly knocking him over. He shoved Dean away from him and made a dash for the stairs. He was able to get through the door and shut it behind him before Sam could grab his pant leg with his teeth.
Dean and Sam barked and scratched at the door.
Bobby quickly opened it for them before hospital security reached them. The two dogs began climbing the stairs as Bobby turned to the security guards and flipped a fake badge open. "My K9s and I have got this covered boys."
Dean and Sam were able to catch up to Dr. Hart after the 3rd flight of stairs. They surrounded him.
"Leave me!" Dr. Hart commanded them.
They refused to listen, even with the vet's power pressing down on them.
Sam snapped at his legs and Dean jumped, slamming into Dr. Hart's back.
Both Dr. Hart and Dean went tumbling down the stairs. There was a crack as Dr. Hart's head hit the bottom. Dean whined as he rolled into the brick wall.
Sam trotted down the steps and nudged Dean with his nose. Dean whined again, and slowly got to his feet, left front paw slightly lifted off the ground.
They were standing there, in Dr. Hart's blood, when Bobby arrived.
Bobby was about to check Dr. Hart's pulse when he gasped and his eyes shot open. He coughed and blood came to his lips.
Bobby grabbed him by the shirt collar and pointed to Sam and Dean. "Turn them back, pants and all, or I'll let you bleed out here. You understand me? And call off the rest of your dogs. Now. No more killing."
Dr. Hart nodded.
Before Bobby's eyes Sam and Dean turned back into their human forms.
"Thanks Bobby," Dean said.
Bobby nodded and went to the second floor to call doctors and nurses to come to the man's aid.
Sam, Dean, and Bobby stuck around at the hospital to tell the local police the story. The one they wanted them to hear. Dr. Hart had used several vicious dogs to kill the victims, dogs the disease control center had already captured. The dogs on the street were not vicious. They could be rehomed once the local animal control captured them. They also told them about the secretary and how she'd helped Dr. Hart.
As for the evil vet himself, when the doctors and nurses were done doing all they could for him, he was left on life support.
The Winchesters and Bobby stuck around the hospital long enough to see the secretary make the mistake of visiting him, and the local police arresting her.
After the arrest the boys and Bobby walked back to his car and he drove them to the motel so they could go get their belongings and the Impala.
As he was driving them there, Bobby noticed Dean rubbing his left hand.
"Hand okay?" he asked.
"Yeah," Dean replied. "Nothing some ice can't fix. Small price to pay for getting back to normal."
They were quiet for a few moments before Bobby spoke up again. "So, what do you boys remember?"
Sam, who was in the backseat, made a face. "Nothing good. My most prominent memory is helping Dean finish chewing his old shoes to pieces."
Bobby laughed.
