Dogs aren’t usually the first animal that comes to mind when you think of scuba diving.

However, these furry friends can make a dive trip especially memorable. It’s not uncommon for scuba diving centers to have a resident dog, whose tasks include watching over the dive gear, guarding the shop, and enjoying the wind in their fur aboard the dive boat. It’s a ruff life.

“Every great dive shop has its own personality, and often, that personality has four legs,” said Kristin Valette-Wirth, chief brand and membership officer for PADI Worldwide, told USA TODAY in a statement. “Meeting a beloved dive shop dog is more than a fun travel moment; it’s an authentic welcome into the local dive community.”

These animals may not be part of the scuba diving itself, but their presence often leaves a lasting imprint on the divers. They provide a warm welcome, emotional support and tail wags to every participant.

“Dogs have a remarkable way of helping us relax, connect and feel at ease, setting the tone for an experience that supports wellbeing before we even enter the water,” Valette-Wirth continued. “It’s also a reminder that some of the most memorable parts of a dive adventure happen before the dive itself.”

Here are some of the most famous dive shop dogs around the world.
