Squeaker Out Means Game Over

This dog has the unique passion of squeaker removal. Given a stuffed dog toy such as this soccer ball, the dog will immediately and strategically open a small area of the toy (one little patch in this example) and pull out stuffing until the plastic squeaker has been found and removed.
 
I could have used a wider aperture and lower ISO setting for this indoor night shot, but I wanted to increase DOF and to reduce the vignetting without using software to do so.
