A dog (of course)
a good camera
a perfect day
and a pretty scenery
Set your camera to a setting that you like best, always keep your camera on at ALL TIMES because if you don't you will miss a lot of cute settings:
Take a afternoon walk with your dog let him/her run around and wait for the perfect moment to take a photo.
You may have your dog sit or lay while you take a photo just keep in mind that a dog loves to move and play. Keep taking pictures of any moments that you love watching your dog do. Don't be scared to take a lot of pictures you can always delete the ones you don't like.
