Lost dog survives 43 days alone in Colorado mountains

Steven Maa was halfway through moving from New Jersey to California when he stopped in Montezuma, Colorado for a ski trip on December 28. He left his dog Rocky with a pet sitter. Rocky panicked and bolted into the mountains.

What followed was the kind of loss that feels final. Steven and his partner Kate searched through a snowstorm until 3 a.m., but Rocky had vanished into winter terrain. The mountains around Montezuma don't forgive mistakes—snow, wildlife, exposure, the slow math of survival. Steven contacted Summit Lost Pet Rescue, but as days turned into weeks, the silence hardened into something close to certainty.

Brandon Ciullo, who founded the rescue a decade ago, had seen this pattern before. He'd learned to calibrate hope carefully. "My biggest worry and concern is vehicles, then wildlife and then environment," he told Steven, trying to anchor him to what actually kills lost dogs in the wilderness. It wasn't usually the wilderness itself.

Forty-three days later

On day 43, a Ring camera in Montezuma captured movement. A dog. Brandon got the alert while handling another rescue call. He apologized to the owner he was with, explained the situation, and drove toward Montezuma. A dog missing that long doesn't usually come back walking.

When Rocky arrived at the facility, Brandon couldn't quite process what he was seeing. "He was running around. He went straight to the toy bin," Brandon said. "We couldn't believe that this dog that hasn't probably eaten in 43 days had this much energy and this much life to him."

That energy matters. It suggests Rocky found water. Possibly small animals. Maybe someone left food out. Or maybe—and this is the part that's harder to explain—Rocky's body simply refused to quit.

When Steven held his dog again, he noticed something that surprised him more than the reunion itself: Rocky hadn't changed. His personality was intact. His affection was intact. "It didn't seem like his personality or his emotions had changed at all, so that was super comforting to see and surprising," Steven said. "I feel like he jumped straight back into his old personality and just being a cuddle bug."

What's interesting about this story isn't just that Rocky survived—it's what his survival suggests about the animals we live alongside. Dogs are built for resilience in ways we don't fully understand. They navigate by senses we've largely abandoned. They endure in conditions that would break most of us. And sometimes, they come home.

For Brandon, rescues like this one—the ones that defy the statistical odds—are why he keeps doing the work. They're rare enough to matter, common enough to suggest that surrender might be premature.
