We try and take pictures of the new dogs on their first or second day. This doesn't always happen however and suddenly we realize that we'll have a dog that has been coming for months that we don't have any decent pictures of.
In Snoopy's case, he was a little shy to start so we didn't want to intimidate him more by sticking a camera in his face. He is feeling much more relaxed now and while he is definitely camera shy and does not like to look straight at the camera, I can trick him occasionally by making weird noises to get him to turn his head a little bit.
Jake on the other hand, has been confident and playful from day one. He only plays inside though. So every time we went to take a picture of him outside he would just stand there and look away (or he'd be doing his business and we don't need a picture of that!).
You'll notice Jake is still not looking at the camera. We will just have to keep trying for better pictures but I didn't want them to be neglected on the blog.
