Jay McMaster told Channel 2's Tony Thomas the animal is still suffering a month after the attack.
"He's not feeling good right now, I mean he's hurting," said McMaster.
"He's still got stitches here, and here, and his bottom lip here," McMaster said as he showed Thomas the injuries.
McMaster said he came home one Sunday afternoon to find the horse cowering near the barn and bleeding. McMaster called police, but his son shot and killed the dogs before officers arrived, fearing they could attack again.
The dogs' owner wrote in a statement to police that the two pit bulls had run away while her ex-husband was walking them. The woman told police her daughter was devastated because the dogs had never been aggressive, according to the police report.
Clayton County Animal Control charged the owners of the dogs with four minor violations. The dogs' owners could not be reached for comment.
McMaster told Thomas he would have liked a stronger punishment to match what his horse has suffered.
"He's been with me a long time. I hate he had to go through this, but I guess better him than a human being," said McMaster.
