What a beautiful animal.
Your beautiful pup is growing and growing!
What a beauty!
I do notice a slight green haze on the photograph though- I would definitely tone down the green a bit to get the colours more natural.
Beautiful dog.
I have two suggestions:
1. Watch your backgrounds.
2. Get down, or in some other way find an unusual perspective.
I'm not a great fan of Scott Kelby, but the second comment reflects something he wrote about flower photography that was the single most useful suggestion I found when I was starting out. He said that it is essential to find an unusual perspective, something that is different from the perspective of a person just walking by. if you don't, you generally end up with what looks like a snapshot of a flower. I think this applies to pets as well--that is, one way or the other, find a way to make it not look like what someone would see walking by.
In the case of flower photography, one option--which you don't have with pets--is to get very close and do macro. At longer distances, however, it is sometimes hard to find a perspective. However, I just about never shoot looking down from standing height.
