Smart dog, small, not yuppy?

Question
Hi,

I was wondering if there is a small dog not more then 20 pounds that is smart easy going loving and a great companion like a labrador retreiver? also not overly yuppy?

Answer
My first choice would be a shi tzu as they are a very smart,friendy and also are not yappy like a lot of small dogs,they do need brushing and need to be clipped

My second choice would be a toy rat terrier,as they are also very smart and not yappy,they have short hair and don't need much brushing but need a coat in the winter
