Veterinarian Kay Creese said it was the first time she had dealt with "blatant abuse" on a dog, KFVS reported.
“The smell on this dog was horrible, so I made the decision to immediately take him into surgery to explore because the muzzle here yesterday was twice the size when he came in, and then matted, and just oozing with pus and fluids," Creese told the television station.
Authorities were alerted to the dog's condition Friday, KFVS reported. He was among two dogs surrendered to police officers.
According to Stan Reno, deputy chief of the Carbondale Police Department, the dogs' owner gave up the animals willingly and they were taken to Jackson County Humane Society, KFVS reported. Officials at the humane society sent the dog bound by rubber bands to St. Francis Community Animal Rescue and Education, the television station reported.
The Carbondale Police Department is investigating the abuse case, according to WPSD.
