Your opinions on good dog breeds please

I have a Brittany Lab mix. She's very good at barking when people come around, which is all I was after anyway. (I'm relying on the Remington if someone actually comes in the house), but then she doesn't scare friendly people once they're in the house.

A big type guard dog (or a dog like mine) is going to be very energetic and need lots of attention. Not really compatible with most college lifestyles.

A little yip dog may seem annoying, but it might be a good bet. Small poop. Easy to wash. Can be inside a lot. Don't shed every damn place. Will bark to warn you if someone is trying to busy into your place.

Most importantly......Chicks DIG them.
