In terms of the fur, it's better. If you used a flash (looks like you did), I'm amazed there is no doggie demon eye. I can't get a flash photo of mine that doesn't have it. You have a camera capable of very low light photography. Don't be afraid to turn off the flash and play with the ISO to get a natural look. It looks like you have enough moving life there to practice with.
Others will probably chime in here. If you really want critiques of your photos, you might want to post some larger photos. It makes details easier for us to see.
