Too bad about the tree in the background, the focus is also a little lacking since you seem to have focused on the apple and nose of dog only. You probably know already but focusing on eyes first and then moving the camera to a new composition works better. Nice and healthy looking dog.
Photo is a little soft and the arm has way too much light on it. Check your settings. If you went auto you should have used manual and adjusted your shutter iso etc. cute idea tho.
