It is a good portrait of the dog - unfortunately, the other elements in the photo distract from that and detract from the overall shot. Having the woman somewhat more in the b/g might help, if her figure had more horizontal separation from the dog. A different pose would contribute to make a better shot. (squatting isn't the best way to portray people in general) The blown out sky in the upper left of the photo adds nothing, and the brightness is distracting. A graduated ND filter will help immensely with that. For this kind of shot, where there is subject movement, bracketing for HDR isn't the answer, but some underexposure, and using PP to bring up shadows might be a better solution.
You have a good eye for composition, so all you need to work out are the technical details.
