Eight miles off the northwest coast of Anguilla, beyond Prickly Pear and the smaller cays, lies an island almost no one ever reaches. Dog Island covers roughly 510 acres of low cliffs, pale sand, and dense scrub, and for most of the year its residents are its birds. It has now come to market at $222 million through the Anguilla agency Dream Dwell Realty, and it ranks among the largest privately held islands in the eastern Caribbean.
That is the rare part. Private islands are uncommon anywhere, and in Anguilla, with only a handful of small offshore cays, a holding on this scale, long owned by a single family, surfaces perhaps once in a generation.
The name is folklore. There are no dogs on Dog Island and, by most accounts, never have been. Early chart-makers are said to have thought its outline resembled one, though plenty of Anguillians think it looks more like a fish.
What lives there is the better story. Recognized by BirdLife International as an Important Bird Area, Dog Island is one of the most significant seabird sites in the Lesser Antilles. In nesting season it carries several hundred thousand birds, including a sooty tern colony running into tens of thousands of breeding pairs, along with brown boobies, masked boobies, and frigatebirds whose males inflate a scarlet throat pouch during courtship. The surrounding reef forms part of a protected marine park where green and hawksbill turtles nest.
There is a quieter conservation story too. For decades the island’s wildlife was preyed on by invasive rats that had arrived by boat. In 2011 the Anguilla National Trust and its partners began a full eradication, completed the next year, at the time the largest such effort on any Caribbean island. The bird colonies have recovered since.
Human traces are faint. A dirt airstrip cut by a former owner generations ago has long fallen out of use, and Great Bay, on the north shore, offers the only sheltered landing. Beyond that there is scrub, cactus, a few wild goats, and a great deal of sky. Its beaches are the kind that made Anguilla’s name across the Caribbean, and almost no one ever walks them.
For a buyer, this is less a building plot than a chance to hold and look after a working wild ecosystem, an acquisition closer to legacy than development. Anguilla, a British Overseas Territory named the top island in the Caribbean, Bermuda, and the Bahamas in Travel + Leisure’s 2025 World’s Best Awards, levies no income, capital gains, or estate tax on individuals, and international buyers purchase through the territory’s Alien Land Holding License process.
“An island like this does not come along often,” says Glenford Walters, principal of Dream Dwell Realty. “Whoever takes it on becomes the steward of something rare.”
