Oriole

He was running through the Tundra, snow covering his pelt. He knew he saw something! Aha! He saw a dark shape moving along the ground. He moved closer, making himself as flat as he could so he wouldn't be seen. It was a pack of dogs! This was perfect! Now he could show his sister that he was really strong. He ran up to the dogs and not the largest one's leg. He winced and suddenly all the dogs were turned on him. I didn't think this through, did I? He jumped on another one and bit their neck. He was thrown off into the snow and, before he knew it, he was being chased through a blizzard by a pack of dogs. He saw a dip and the ground and started to run as fast as he could to the hiding spot. However, he was picked up off his paws by a large creature! He struggled to get free, but the creature wasn't letting go. The creature ducked into a cave and let him go. "What was the big idea?!" He paused to study the creature, he was a wolf! With… weird markings? "And who are you?" The wolf took a moment to shake off the snow before saying, "I'm Bongo and I just saved your life, pup."
"I was doing fine all on my own!" He growled
"Sure." Bongo scanned the area in front of the cave before saying, "We should stay here until the snow stops."
Oriole huffed and curled up at the back of the small cave to wait out the blizzard. He kept an eye on the large wolf for a while before drifting off to sleep.
He woke up to someone nudging his side. "Sis, stop!" It continued "Seriously, Cavern, I can wake up on my own- Oh." The wolf nudging him awake was Bongo. "Come on pup," he said, "Do you know your way back to your pack?"
"'My pack'?" He laughed "Seriously? I live with my sister, the only wolf I need…. But yes, I know where we live."
"Good, I'll come with you to make sure you get there."
He grumbled all the way to the hole him and his sister lived in… but when they got there…. Everything was destroyed and his sister was gone. "Cavern? Cavern! CAVERN!" He barked. Then he heard it… howls in the distance… this DOGS! He started running in the direction of the howls, but Bongo picked him up again and instead brought him home. "What are you doing?! I need my sister!" He spat at the older wolf. Bongo didn't say anything, but just kept going until rock turned to grass and then turned to trees. Where was Bongo bringing him? Then he was carried into a clearing where a grey-blue wolf came to greet Bongo. Oriole was put down and he sat next to Bongo, pouting. "Who is this?" The blue wolf asked Bongo. "A pup that I found running from a pack of dog-"
"Fighting dogs, I was fighting them" he corrected Bongo
"Yes, fighting them. He lived with his sister, but when we went back, she was gone."
The blue wolf nodded and started pushing him to a cave when he turned around and snapped at her. She pulled away and instead picked him up and let him down in the cave where there was were two pups. One with glowing spots and the other… "Cavern!"

For his pack name, he is now called Dog Fighter. Correctly, "Dog Fighter". Not "Dog Run Awayer Fromer", Bongo. His sister still calls him Oriole, which he likes, but the rest of the pack calls him Dog Fighter.
