What a pity... she looks so much worse than in the first pics, she looks as though the only thing that will bring her back is a long stretch of vet care... I don't know what I'd do in your spot other than what you have already done.. I hope the sherriff does something.. I would have a very hard time being friendly neighbors after this... give the sheriff another call... anything to get this girl help.. hell, give me his number and the address where that poor girl is and I'll call !! Enough people calling and maybe something will happen,,,
Never approach a bull from the front, a horse from the rear, or a fool from any direction.!!!
