Of my two, Bubba is the ball of fire. He is moving constantly, playing ball or tug or constantly on my lap. He loves kids and wants to get up at the butt crack of dawn to run around the yard and eat.
Sissy, on the other hand, is to put it bluntly, is a couch potato but sweet and more loving. She was a rescue and the only thing she will do is work with a treat ball. No other toy gets her attention. She will accept at pat from children but is not really interested in them. She will snuggle in bed until I get up.
They have totally different personalities. He is outgoing and friendly, playing with dogs and people. She shy, clingy and rarely engages with dogs at the dog park.

they have personalities similar to my two legged children.
