Black said he’s hopeful his son will get his dog back.
He said the obvious blue patch on the left side of the dog’s face will help people identify the dog.
"I've already had one young lady inbox me and tell me they saw the dog in Millington. So he could be in that area,” Black said.
Black said he is encouraging whoever is in possession of the dog to bring in to the vet.
