When photographing pets, the best thing you and do is relax and have fun with them throughout the process. They can certainly be buggers when it comes to getting them to look at the camera, so letting them do their thing without focusing on that can allow you to capture some real gems of them, well, just being them! Our crazy Labrador-Retriever mix is one that definitely needs a run before he will sit down for a photo. Even then, he seems to run the other direction when I pull the camera out. I have found it helpful to set my camera up on a tripod, attached to a cheap remote shutter release (i.e. allowing you to take a picture when you are not right at the camera), and keep the image more zoomed out than I want my final image to be. This way I can distract him, and he won't think that I'm actually taking a photo, and if he moves around, he will stay in the shot. Anything I want to crop out of the photo, I can do later.
