Characters

• Nick is a tall, orange dog with a proud stature. He is very fascinated in Earth life, especially television, and his love interest, Sofia. He is lazy, loves pleasure, and is very optimistic, not having a bad thought about anyone. Unlike other dogs, he is a vegetarian. He is not too smart compared to his friend, Perry, although the two can work together well.
• Perry is a small, blue dog resembling a beagle. He is highly intelligent, and is extraordinarily talented in technology and can build highly complex apparatus out of simple human objects. The easy-going Nick often causes him a lot of trouble, especially when he messes up his return plans. Despite this, they are friends, and they both work well together.
• Lucy is a little girl who wanted nothing more than a dog for her birthday. When a UFO crashed overnight in her garden and the normally upright and talking dog manners Nick and Perry had to disguise themselves as earth dogs, she thought they were a gift from her father. Lucy is a very bright, adventurous only child.
• Frank is a history professor and a single father. When Lucy thinks the two dog manners are a present from him, he can't bring himself to disappoint her and keeps Nick and Perry. Frank is often a little absent-minded and gullible.
• Mr. Smith is Frank and Lucy's spiteful neighbor and a part-time UFO hunter who tries to catch Nick and Perry in non-dog behavior and then sell them to science.
