We have several Prairie Dogs running around our property in Mt. The locals who own livestock despise them because they break their legs from stepping into their burrows and are fair game. Until we move there permanently and have horses I will let them do what Prairie Dogs do.
I think you comp and works great for the subject. I think you have a dark halo around the back and head of the P.Dog. I get them sometimes on subjects with similar tonality as the BG.
