honestly ... it is not a very good photo. The image is soft/OOF, lacks enough DOF for the eyes and ear to be in focus, poorly composed needless cutting of an ear with a somewhat distracting background with a pair of poles sticking out the the poor pooches head.
If this images was sharp it could be somewhat saved through cropping and increasing the contrast ... but there is nothing one can do about the softness caused by a low shutter speed or too shallow due to an aperture of 1.4.
