Dog Stabbed in Head

Disgusting news from WGCL in Atlanta:

“A pit bull was rushed to the Atlanta Humane Society Wednesday, with a knife in its skull.  Pit bulls often have a bad reputation as being aggressive dogs, but Mama, the injured dog, is very sweet, said the dog’s owner…..Dr. Paula Murray performed surgey on Mama to get the blade out. Within minutes after the operation, Mama was up and alert.”

What kind of degenerate idiot stabs a dog?
