In 2016, Charlie lost both of his eyes from glaucoma. His left eye was removed in 2016 and his right was taken out a year later.
His owners, Chelsea and Adam Stipe, decided to get a puppy who turned out to be a savior for Charlie.
As the two dogs became friends, Maverick began to notice that something was different about Charlie.
“When they would play, Maverick would realize that Charlie would lose the toy sometimes, so (Maverick) would pick it up and put it back in front of him to re-engage playtime,” Chelsea said.
