I'm a dragon and he's a dog.He's very laid back and I'm more energetic but he is my center.

According to Chinese astrology, you seems not to be that compatible, but there is amendment for a good future for you two. I suggest you learn to appreciate each other's strength and overlook each other's shortcomings so that you will get along well better. Also you need to tell him to be more confident and positive so that there will be much more energy for your relationship.
