An adult Alexander Archipelago wolf typically weighs 30–50 pounds (14–23 kg) and stands about 24–26 inches (61–66 cm) tall at the shoulder, making it similar in size to a large husky.
This wolf lives only on the islands of Southeast Alaska. Its small body size, dark coat, and island lifestyle make it one of the most unique gray wolf subspecies in North America.
Alexander Archipelago Wolf Size at a Glance
Average Weight (30–50 lbs)
Most adult wolves in this population weigh between 30 and 50 pounds. Males usually land at the heavier end, while females stay closer to 30–40 lbs. For comparison, an average German Shepherd weighs about the same.
Average Length and Shoulder Height
Nose-to-tail length runs 3 to 4.5 feet (91–137 cm). Shoulder height ranges from 24 to 33 inches (61–84 cm). The tail itself is shorter and less bushy than other wolf subspecies, which helps this wolf conserve body heat in a wet, cold climate.
Male vs. Female Size Differences (Sexual Dimorphism)
Like most wolves, this subspecies shows sexual dimorphism. Males carry more muscle mass around the neck and shoulders and have a broader skull. Females have a slimmer frame and a narrower muzzle. Both sexes share similar height and length ranges, but weight is where the gap shows up most.

Why Is the Alexander Archipelago Wolf So Small?
Island Dwarfism and Insular Isolation
When animal populations get stranded on islands, they often shrink over generations. Biologists call this pattern island dwarfism. Limited land, limited food, and no mixing with larger mainland populations all push body size down over time.
The Alexander Archipelago wolf followed this exact pattern after becoming isolated in the Alexander Archipelago roughly 7,000–8,000 years ago, near the end of the last glacial period.
Role of Prey Size in Body Size
This wolf relies heavily on Sitka black-tailed deer, a smaller deer species than the elk or bison herds mainland wolves chase. Smaller, more consistent prey doesn’t demand a bulkier hunter.
Alexander Archipelago Wolf Size Compared to Other Wolves
Alexander Archipelago Wolf vs. Interior Alaskan Wolf
Interior Alaskan wolves (sometimes called Yukon wolves) can weigh 85 to 145 pounds, nearly triple the weight of an Alexander Archipelago wolf. Interior wolves hunt moose and caribou, which favors a much larger, more powerful build.
Alexander Archipelago Wolf vs. Northwestern Timber Wolf
The Northwestern timber wolf, found across British Columbia and parts of Alaska, averages 70–110 pounds. Again, the Alexander Archipelago wolf comes in at roughly half that weight, reinforcing just how much island life shaped its frame.
Alexander Archipelago Wolf Size vs. a Large Dog
This wolf is close in size to a Labrador Retriever or German Shepherd. It’s taller at the shoulder than most dog breeds but carries a leaner, more athletic build suited for forest travel and deer hunting.
Alexander Archipelago Wolf Size by Age
Newborn Pup Size and Weight
Pups are born blind, deaf, and weigh close to 1 pound. Births happen in dens built four to five weeks in advance, often tucked into rock crevices, hollow tree roots, or abandoned beaver lodges.
Juvenile Growth Timeline
By three weeks old, pups leave the den for short periods. By six months, they’ve grown enough to start joining adults on short hunting trips. Growth is fastest in the first four months, fueled by a steady diet once weaning begins.
When Wolves Reach Full Adult Size
Most individuals reach full adult weight and height by 12 to 24 months. Skeletal growth finishes first, while muscle mass, especially in males, continues filling out through the second year.

FAQs About Alexander Archipelago Wolf Size
How big is an Alexander Archipelago wolf compared to a regular gray wolf?
It’s noticeably smaller. This wolf weighs 30–50 lbs, while mainland gray wolves often weigh 70–145 lbs.
What is the average weight of an Alexander Archipelago wolf?
Adults average 30 to 50 pounds, with males typically weighing more than females.
Are male Alexander Archipelago wolves bigger than females?
Yes. Males are heavier and have broader skulls, though both sexes share similar height and length.
Is the Alexander Archipelago wolf the smallest gray wolf subspecies?
It’s among the smallest in North America, though a few other isolated subspecies come close.
How tall is an Alexander Archipelago wolf at the shoulder?
Adults stand between 24 and 33 inches tall at the shoulder.
Conclusion
The Alexander Archipelago wolf size tells a bigger story than just numbers on a scale. Island isolation, a deer-based diet, and genetic separation from mainland wolves all combined to shape a smaller, leaner predator built for Southeast Alaska’s rainforest islands. At 30–50 pounds and under three feet tall at the shoulder, this wolf proves that size isn’t what makes a top predator — adaptation does.
