The Pooch Selfie is a smartphone attachment that holds a tennis ball above the camera so your dog will look at it when you're taking pictures of them. It's an already funded Kickstarter campaign so $13 will get you one when they ship this December. Me? I get my dog to look at the camera the old fashioned way: taping a treat to it. Either one is a great way to get your dog to chew up your phone.
Keep going for a couple more shots and the Kickstarter video.
Thanks to Debra, who agrees they need to make the same thing for cats except it should look like a red laser pointer dot. Just prepare to be attacked.
