The Borzoi is classified by The Royal Kennel Club as a large breed, typically weighing 27–48 kg as an adult, with a median life expectancy of around 12.0 years, according to a 2024 analysis of UK veterinary records by Dogs Trust. Originally bred by Russian nobility to course wolves across open terrain, the Borzoi combines remarkable speed with a calm, dignified temperament at home.

What this means for your Borzoi

Like other deep-chested sighthounds, Borzois are at increased risk of bloat (gastric dilatation-volvulus) — knowing the warning signs and seeking emergency care immediately can be lifesaving. Cardiac issues, including dilated cardiomyopathy, are also reported in the breed.

Sighthounds including the Borzoi can be unusually sensitive to certain anaesthetics due to their low body fat, so it's worth flagging the breed to your vet before any procedure.

When is a Borzoi considered a senior?

Under The Royal Kennel Club's size-adjusted guidance, large breeds like the Borzoi are generally considered senior from around 5 dog years old.
