Cosmo is the sweetest girl ever. She's calm, graceful, brilliant, and very affectionate. She's the smartest dog I've ever encountered, listens and pulls words from sentences and knows what you're doing. Star is a tank of a little bear. She's clumsy, loud, and crazy (in a good way). She's a born follower, she just wants to be where everyone else is. She is sweet, silly, playful and not quite so smart. She is also fearless, while she respects Cosmo's position as the elder dog, she fears nothing. She's the type that would jump out of an airplane, then check and see if she had a parachute or not.
