Duke

Duke is a mix of two large dogs, or perhaps he's a very large mongrel. His fur is very thick and fluffy, fluffier than a Spitz's, and his height is almost the same as a weakling's. He's a stray dog, and he runs away from people who catch stray dogs.

He and his sister run around the city, knocking down everything they come across along the way, trying to hide from people.

but they are eventually caught and both end up in a truck and they are driven to a shelter

Duke is sitting in the cage trying to fit, and the same with his sister
