Polly want a cracker? No, Polly wants a forever home! Approximately nine years old and an Australian Cattle Dog mix, Polly entered the Cleveland County Animal Control Services shelter in North Carolina on August 7th as a stray. She had what appeared to be a gunshot wound on her right shoulder. She was also heartworm positive. The combination of being older, injured and heartworm positive did not bode well for Polly.
