Zero the Dog

Zero is a gentle dog with a bright personality that enjoys going on adventures and being pet while sitting in someone's lap. He is a confident leader on dog walks, and is an expert at navigating any path that he has previously crossed, no matter how lost his masters may get.

Zero sometimes gets overshadowed by Ruby, which makes it hard for others to get deeply connected to him, but it doesn't appear to bother him. Zero and James are strongly bonded, and they seem to prefer spending time with each other.
