The borzoi (literally "fast") is a breed of domestic dog (Canis lupus familiaris) also called the Russian wolfhound and descended from dogs brought to Russia from central Asian countries. It is similar in shape to a greyhound, and is also a member of the sighthound family.


Borzoi males frequently reach in excess of 100 pounds (45 kg), ~120 pounds. Males should stand at least 30 inches (about 80 centimeters) at the shoulder, while females should not be less than 26 inches (about 66 centimeters). Despite their size, the overall impression is of streamlining and grace, with a curvy shapeliness and compact strength.
The borzoi is a quiet but athletic and independent dog. Most borzoi are almost silent, barking only very rarely. They do not have strong territorial drives and cannot be relied on to raise the alarm upon sighting a human intruder. They are gentle and highly sensitive dogs with a natural respect for humans, and as adults they are decorative couch potatoes with remarkably gracious house-manners. Borzois should never display dominance or aggression towards people. Typically however, they are rather reserved and sensitive to invasion of their personal space; this can make them nervous around children unless they are brought up with them from an early age. Despite their size they adapt very well to suburban living, provided they have a spacious yard and regular opportunities for free exercise.
A common misunderstanding about the intelligence of breeds in the Hound group stems from their independent nature, which conflicts with the frequent confusion between the concepts of "intelligence" and "obedience" in discussions of canine brainpower. Stanley Coren's survey of canine obedience trainers, published in the book The Intelligence of Dogs, reported that borzoi obeyed the first command less than 25% of the time. Coren's test however was by his own admission heavily weighted towards the "obedience" interpretation of intelligence and based on a better understanding of "working" breeds than hounds.
Unfortunately the publicity given to this report has led to unfair denigration of breeds which are under-represented in obedience clubs and poorly understood by the average obedience trainer."Work" for hound breeds is done out of hearing and often out of sight of the human companion; it is an activity for which the dogs are "released", rather than an activity which is "commanded". In obedience terms, borzoi are selective learners who quickly become bored with repetitive, apparently pointless, activity, and they can be very stubborn when they are not properly motivated. For example, food rewards, or "baiting", may work well for some individuals, but not all. Nevertheless, borzoi are definitely capable of enjoying and performing well in competitive obedience and agility trials with the right kind of training.Like other sighthounds they do not cope well with harsh treatment or training based on punishment, and will be extremely unhappy if raised voices and threats are a part of their daily life. However like any intelligent dog, borzoi respond extremely well to the guidance, support, and clear communication of a benevolent human leadership.


Borzoi are born with specialized coursing skills, but these are quite different from the dog-fighting instincts seen in some breeds. It is quite common for borzoi at play to course (run down) another dog, seize it by the neck and hold it immobile. Young pups do this with their littermates, trading off as to who is the prey. It is a specific hunting behavior, not a fighting or territorial domination behavior.

Life expectancy is 7 to 10 years. Exceptional individuals have lived to be more than 14 years of age. Dogs that are physically fit and vigorous in their youth through middle age are more vigorous and healthy as elderly dogs, all other factors being equal. In the UK various cancers, followed by cardiac problems, seem to be the most frequent causes of premature death.

As with other very deep-chested breeds, gastric torsion is the most common serious health problem in the borzoi. Also known as bloat, this life-threatening condition is believed to be anatomical rather than strictly genetic in origin. Many borzoi owners recommend feeding the dog from a raised platform instead of placing the food-dish on the ground, and making sure that the dog rests quietly for several hours after eating, as the most reliable way to prevent bloat.
Less common are cardiac problems including cardiomyopathy and cardiac arrhythmia disorders. A controversy exists as to the presence of progressive retinal atrophy in the breed. A condition identified as Borzoi Retinopathy is seen in some individuals, usually active dogs, which differs from progressive retinal atrophy in several ways. First, it is unilateral, and rarely seen in animals less than 3 years of age; second, a clear cut pattern of inheritance has not been demonstrated; and finally, most affected individuals do not go blind.

The issues involved in raw feeding may be particularly relevant to tall, streamlined breeds such as the borzoi. It is interesting to note that the Hortaya Borzaya, undoubtedly a very close relative, is traditionally raised on a meager diet of oats and table scraps. The Hortaya is also said to be intolerant of highly concentrated kibble feeds. Basically, a lean body weight in itself is nothing to be concerned about, and force-feeding of healthy young borzoi is definitely not recommended.
