A full-grown Borzoi is a giant dog, weighing about 100 lb as an adult.

Adult weight: 100 lb
Also in kilograms: 45.4 kg
Size class: Giant

As a giant breed, a Borzoi keeps growing for longer than a small dog — larger breeds reach their adult weight months later (Hawthorne et al., 2004). Expect steady growth well past the first year.

Weight varies within the Borzoi by sex, genetics and health, and mixed-breed dogs fall between their parents. This is a typical range, not a guarantee.
