Mack, the pit bull was formerly abused and placed on the euthanasia list after a shelter labeled him as aggressive.
Less than two years later, Mack is taking care of three tiny foster kittens.
Moving clips, from late April 2020, were filmed in the adoptive New Jersey home that saved Mack by teaching him how to love.
Analisa, the filmer told Newsflare: "Mack and his brother were tied to a tree in Tallahassee without food or water.
Mack had bare elbows and little scars on his face.
After they were removed from that nightmare, they were brought to the shelter.
His brother was adopted shortly after.
"Mack, however, had a more difficult transition.
Whenever someone would come to his kennel, he would get aggressive.
He was placed on the kill list due to his behavior.
However, the same man who rescued him noticed that while he was being aggressive, he was also soiling himself.
He was absolutely terrified!
"Chris asked the shelter to give him time to work with Mack.
After four months in the shelter, Mack went to his foster home, and he was only there for a week when I adopted him.
"Now, during the quarantine, I’m fostering three kittens, and he genuinely thinks that he’s their dad.
He licks the formula off their faces, herds them when they scatter, and cuddles up for naps after feeding time."
