The story begins with Chase's flashback.
He was training in the police academy and he was one of the best dogs there. One dog was jealous of him.
He was amber eyed Hovawart. He was little bigger than Chase and older about a year (everything is in dog ages). His name was Bolt. He wasn't very nice to Chase. Expecialy that day...
Chase was going to his resting place after the day's training. Bolt followed him. Chase was ready to go to sleep when something or someone took from his collar and threw him into the wall. Chase saw that the attacker was no other than Bolt. Now Bolt's paws were on Chase's chest. "You were their favorite long enough," Bolt said:" Now when i finish with you then i will be the best pup they ever had." Chase growled when Bolt let go of him. "So you think that murdering somebody will help get you to be police dog?" Chase asked. Bolt took something from the box what he took there. Bolt laughed and said:" I won't murder you. I want that you are unable to train anymore." He jumped on the German Shepherd pup and put a muzzle on his mouth. Chase wanted to shake it off but he couldn't. Chase saw that Bolt tried to find something from the box so he wanted to escape, only to find that the door was locked.
Chase felt that somebody bushed him over and he fell into the side. Chase growled at the pup. Bolt only laughed. "You won't escape from me," Hovawart said as he walked closer and put the handcuffs on Chase's paws. Bolt whispered to him:" And if you want to tell anyone about that then i will be more violent." He took the hammer and hold Chase down with his stomach on the ground. Then somebody knocked on the door. It was Chase's opportunity. He kicked Bolt to his nuts and the bigger dog gave out a painful howl. "You asked for it," Bolt said. But before he could do anything the police chief opened the door and saw Bolt with Chase.
Bolt was kicked out from the academy. He swore to get the hold on Chase.
Few years later...
Paw Patrol were on the beach. There they heard a tire sqreetching. Chase saw that there was a race car. And the car looked like it belonged to the dog. And there was a dog. He reminded Chase of someone. The dog looked at Chase and jumped out of the car. Then he looked around and ran towards Chase. "Hi," the dog said:" I need some kind of...help. Well
...we need help." "We?" Chase asked. Dog nodded and said:" My team needs to be part of the race but one of our teammates is badly injured. Now we need the money to get the proper treatment for him and save my owner's business." "Why you ask me?" Chase asked. The dog sighed and said:" I knew that you won't agree because of our past. But we need the best of the best because if we won't win then there is nothing what will save my owner's job or our teammate." Chase asked:" Our past?" Dog said:" You don't remember? I'm Bolt."
