In terms of his personality, he is incredibly warm - hearted. He forms strong bonds with the characters he meets, similar to how a dog bonds with its owner. His physical appearance, with the soft white fur, gives him a cuddly look despite his large size. And he has a great deal of courage, not hesitating to face danger when his friends are in trouble, which is also a trait that can be associated with dogs in a way.
If we assume the 'dog dragon' refers to Falkor in 'The Neverending Story', his characteristics are quite interesting.

His white fur gives him an almost otherworldly appearance. And he has a sense of wisdom and understanding that helps the heroes in the story, showing his intelligence which is different from the simple - mindedness often associated with dogs but still an endearing quality.
