Titus

"Titus is very much the youngest sibling of the solar system group. They are a bit of a klutz in usual puppy fashion, tending to fall behind the group a bit and sometimes he takes a while to understand a joke. In general the other celestdogs are protective of him. He’s small, even for a puppy, and if anyone dared tease them for their size, the others would immediately jump to defend them."
