“It feels good being able to protect my puppies, my animals,” said Hull. “It feels really good, keeping ’em safe.”

“There was no thought in this for him whatsoever,” said Cassie Lackey of the Humane Society of North Texas. “It was just instinct in him to go and get this puppy that he felt responsible for.”

Summer will go home to her new family this weekend.
