Meet Henry, an 87-year-old grandpa, and his cherished golden retriever friend named Peyton. Since the day Henry was first introduced to Peyton as a puppy, the pair have been inseparable.

Indeed, with everything Henry does, he keeps dear Peyton in mind — and that includes Halloween.

“My grandpa is obsessed with Peyton! She’s our family dog and they live together in the same house,” Matt Poulton, Henry’s grandson, told The Dodo. “She sleeps in his room and loves to lay next to him throughout the day. They spend most of the day in the house together.”

Not long ago, at the suggestion of his grandkids, Henry watched the 2009 Pixar film “Up” — a movie in which a dog and older man like him are central characters.

“We always said that my grandpa looks like [the character] Mr. Fredricksen,” Poulton said.

The resemblance really is quite uncanny — but Henry isn’t the only one with an animated doppelganger. The canine character, Dug, looks a bit like Peyton, too.

With Halloween approaching, “Up” evidently returned to Henry’s mind when it came time to decide on a costume. Sure enough, he opted for one that his beloved dog could be a part of.

Henry and Peyton knocked it out of the park.

The costume couldn’t be more perfect, with the dog’s au-naturel look more than sufficing for her part. But what’s sweeter than the image of them together, is Henry and Peyton’s friendship behind the scenes.

“He always talks about her to other people,” Poulton said. “They definitely make each other happy.”
