Borzoi adult size: tall first, heavy second
A fully grown Borzoi stands at least 28 inches at the shoulder for males and at least 26 inches for females, and many individuals finish taller than those minimums. Weight runs about 75 to 105 pounds for males and 60 to 85 pounds for females. Those figures can mislead people who picture a bulky dog, because the Borzoi spreads its weight along an exceptionally long, narrow body with a deep chest, a tucked waist, and fine, elegant bone rather than width.
A sighthound silhouette, not a mastiff build
Everything about this breed's size is vertical and horizontal rather than thick. The neck is long, the back has a graceful rise over the loin, and the legs are built for covering ground, so a standing Borzoi often reaches an adult's hip and can rest its narrow head on a dining table without stretching. When the dog lies down, it needs a bed sized for length, not width; owners regularly find that standard large beds leave either the head or the hindquarters hanging off the edge.
Growing into that frame takes time
Borzoi puppies grow upward quickly in the first year, then spend many more months adding chest depth, muscle, and coordination. Most are close to adult height by about a year, yet the finished, filled-out dog usually does not arrive until closer to two years old, and some lines mature more slowly still. During the leggy adolescent stage the breed can look almost unfinished, all elbows and ribs, which is normal for a sighthound as long as growth is steady and the dog is bright and eating well.
Space, cars, and fences for a dog this tall
Plan your home around length and height rather than sheer mass. A Borzoi folds itself onto sofas surprisingly neatly, but needs a crate and vehicle space that accommodates the long back and legs, and many owners choose a large estate car or SUV for comfortable travel. Garden fencing deserves real thought: a tall, athletic breed that spots movement at distance should have a secure, high fence, and gates should latch reliably. Raised feeding stands, long leads, and coats sized for deep but narrow chests are the other purchases where Borzoi proportions catch new owners out.
Is this the right size of dog for you?
The honest test is not whether a Borzoi fits your rooms, because most homes can hold one resting dog, but whether you welcome a companion whose head appears over counters, whose tail sweeps at coffee-table height, and who will occupy the full length of a two-seat sofa. People who love the breed find that presence serene rather than cumbersome, since a mature Borzoi is generally calm indoors. Meeting adult dogs at a breeder's home shows the scale far better than any puppy visit, because six-month-olds give no hint of the statuesque animal coming.
Should you take on an adult Borzoi from another home, KinsLe's Transferrable Profiles can hand the dog's profile over to you with its history, health records, and established routines still attached, which matters for a breed whose feeding and exercise habits are so individual.
