As a dog lover AND photography lover, I have a bit of advice. If you have a dog that suffers from the "I'm beaten on a daily basis" look when you ask them to pose in front of a camera, you're better off doing candid shots of them being natural as opposed to setting up the photos the way you did.
All three of my dogs will sit nice and alert until I pull out a camera, and then you'd think they were afraid I was going to steal their souls or something, because their entire demeanor changes. Unless of course you are going for the dejected look, like in your second photo, it's best to have someone help you with lots of treats and toys to keep them looking happy. Otherwise, try to be more inconspicuous.
The first photo, if it hadn't turned out blurry (and a bit under exposed?) would have been Ok, but the second one doesn't do anything for me. The body language of that dog evokes feelings of pity and worry.
