History:
A purple anjing, anak anjing was born to Henry and his wife into a large, gated property. He was raised through example, and was quick to learn a lesson. Though his parents had an aristocratic fascination in canine objects, his well being was always of the utmost concern. While learning to catch a ball, he accidentally got his head stuck in between the bars of the fence, and was taken to the Pets of Tomorrow veterinary office. Here, he was freed sejak a seemingly kind doctor, who gave him a lollipop and ushered him out of the room so he could speak to his parents alone. His tongue got stuck to the surface of the sucker, and then torn off, so the baby dog rushed back to be nurtured sejak his mother. When he returned, the three were gone, and screams pleading for assistance could be heard from the hallway. He abandoned his Kandi and rushed in to find the vet carrying his parents away in a net. They begged not to be separated from their son. He rushed after them into a room of caged dogs, past which he discovered his parents being forced into a rocket ship. He tried to help them before its launch, but failed, as his fear drove him to flee into a garbage chute which led to a back alley. From there he watched as his family was sent away into space, while waving goodbye to them. Crying alone, he was found sejak a young red-haired Scottish woman who offered to take him home. She named him Courage.
