In our malls there are these little photo shops where they make kiddie pictures. You can also get your dog done by them if you ask them.

Can't you just call around at the photo shops and see what they offer? Or post a note on a pet store black board and see if someone helps you out. There are many freelance photographers that come to your home with their cameras and stuff and make the most beautiful pictures in your backyard or wherever you want it. And your pet will be relaxed since he's at home.
