I have 3 dogs, two mutts and a lab. I love all three of them a whole lot. :3
Mutts. Because all dogs need a home and they are typically smarter and healthier than pure breds.
That failing, Labrador retrievers are the sweetest and most loyal dogs I can think of. You can really feel their love. They're also always willing to play, are great swimmers, are really easy going, and get along with other animals.
I also love pit bulls. They get a horrible reputation but I have met some pits that are just as sweet and loyal as labs. They're typically friendly and kind of dopey and mushy. Some can have a mean streak but most are just mooshes.
And here is my lab. :3 He's my big dumb blond!!

Abbie looks really stupid in this picture, but she's actually really smart. And really pretty.
