Meet the dog who’s in better shape than you will ever be.

Ace is the top dog at Dark Dynasty K9s, a breeding kennel that trains elite protection dogs on a ranch in New Hampshire.

The 3-year-old American pit bull trains five times a week, is fed a protein-rich diet and can recognize handguns and knives as weapons.

“If he wasn’t under control, he could absolutely kill a person,” DDK9 owner Marlon Greenan told Barcroft.

DDK9 gained recognition earlier in the year for their 174-pound mega-pitbull, Hulk — Ace’s cousin.

Greenan says he always hopes to get at least three working dogs out of a litter. “When we first look at the puppies, we look for something called a basic prey drive,” he explained.

The 85-pound powerhouse was recognized for his “strong nerve” and “natural drive” at 5 months old. He can now leap into cars and run up the sides of buildings.

“He is absolutely a super dog,” Greenan said. “A one-in-a-million.”
