For decades, bringing a dog to Alaska’s remote Pribilof Islands has been strictly off-limits, part of long-standing efforts to protect the islands’ sensitive wildlife.
Now, for the first time in decades, a very small number of dogs are being allowed back in — but only if they have a highly specialized job to do.
As of August 6, specially trained rodent detection dogs can be authorized to work on the islands, sniffing out invasive rats before they have a chance to establish a population.
The broader dog ban remains firmly in place. Household pets are still prohibited.
Why were dogs banned in the first place?
The Pribilof Islands are home to the world’s largest concentration of northern fur seals, along with enormous colonies of seabirds. Dogs have been prohibited there since the 1980s to reduce the risk of disturbing the seals or introducing disease.
But keeping dogs out created an unusual problem.
The islands are still rat-free, and local communities work hard to keep them that way. Rats can arrive aboard ships, and on remote islands they can spread quickly through ecosystems whose native wildlife evolved without land-based predators.
St. Paul Island has had a few close calls. Rats arriving from ships have generally been caught in traps around the harbor, but one escaped in 2018 and wasn’t found until ten months later, when it turned up dead.
Then, in 2024, someone reported another possible rat on the island.
No rat was ever found.
That uncertainty revealed a problem: one of the best ways to detect a hidden rat was a trained dog, and dogs weren’t allowed on the island.
Enter the rat-sniffing dogs
Under the new rule, specially trained dogs can be authorized to search for invasive rodents, including after a suspected sighting and, in some cases, preventively around vessels or cargo that could introduce them.
These aren’t simply dogs with an enthusiasm for squirrels.
The dogs must be certified to detect rodents, meet Alaska’s health and vaccination requirements, and stay under the control of a professional handler at all times. They can be authorized to work on the islands for up to 180 days.
Even their poop comes with a protocol: handlers must collect and incinerate it to minimize any risk of transmitting disease to native wildlife.
There isn’t actually a Pribilof rat dog waiting for deployment yet. The idea is to have the option ready before a single rat becomes an established population.
So after decades of “no dogs allowed,” the Pribilof Islands have made one highly specific exception:
Dogs are still banned — unless their job is keeping rats out.
