TIP #1. You Need To Be Grounded

Some of your best photos will be of your dog looking directly into the camera lens. So, you'll want to take your pictures low to the ground at your dog's eye level. If you have a tiny-sized dog, guess what, you may find yourself laying flat on the ground (well, you could put your dog up on a higher surface such as a table or bed!).

TIP #2. Going 'au naturel'

You’ll need to take lots of photos, possibly 20 to 30, just to find a few excellent shots. To avoid big green glow-in-the-dark eyes, turn off your flash and use natural light. Some photographers have suggested that the best natural light may be found early in day or late in the afternoon, and should increase your chances of taking a great picture. 

TIP #3. Are You Looking At Me?

Getting your dog to look directly into your camera is not as hard as you may think. Most dogs respond to an excited Do you want...  This question could end with anything: …to go for a walk? …a yummy treat? or, …to go to the park?  Just remember to have your camera in focus and ready to snap your dog’s fleeting glance into your lens. However, once your dog catches on that you’re really not serious about the "Do you wants" and begins to ignore you, you’ll need to try other attention-getters. Try growls, barks, meows, or shrieks (hopefully, you’re doing this in private!). And, finally, try using squeaky toys. Whatever the object, make sure it is positioned next to the camera.
