The Borzoi is a large variety of sighthound, with males frequently reaching in excess of 100 pounds (45 kg). Males should stand at least 28 inches (about 70 centimeters) at the shoulder, while females shouldn't be less than 26 inches (about 66 centimeters).
Temperament:
The Borzoi is quiet, but an 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.
The Borzoi ranks 75th out of 78 in Stanley Coren's The Intelligence of Dogs, being of the lowest breeds in degree of working/obedience intelligence. It took Borzois at least 80-100 repetitions to understand a new command and obeyed the first command less than 25% of the time.
These are dogs used to pursue, or "course", game and they have a powerful instinct to chase things that run from them. Borzoi are built for speed and endurance, and they can cover long distances in a very short time. A fully-fenced yard is an absolute necessity for keeping any sighthound. They are highly independent and will range far and wide without containment, and they have no regard at all for road traffic. For off-lead exercise a Borzoi needs a very large field or park, either fully fenced or well away from any roads, to ensure their safety.
Generally, Borzoi should not be territorially aggressive to other domestic dogs. Against wolves and other wild canids, they are born with specialized 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, seizing it by the neck and holding 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.
Borzoi can be raised very successfully to live with cats and other small animals provided they are introduced to them at a young age. Some, however, will possess the hunting instinct to such a degree that they find it impossible not to chase a cat that is moving quickly. The hunting instinct is triggered by movement and much depends on how the cat behaves.
Some Borzoi do well in competitive obedience and agility trials with the right kind of training, but it is not an activity that comes naturally to them. They are intelligent learners who quickly become bored with repetitive, apparently pointless, activity, and they can be very stubborn when they are not properly motivated. Like other sighthounds they cannot understand or tolerate harsh treatment or training based on punishment, and will be extremely unhappy if raised voices and threats are a part of their daily life.
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.
Like its native relative the Hortaya Borzaya, the Borzoi is basically a very sound breed. OCD, hip and elbow dysplasia have remained almost unknown, as were congenital eye and heart diseases before the 1970s. However, in some countries modern breeding practices have unfortunately introduced a few problems.
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.
Correct nutrition during puppyhood is also debatable for Borzoi. These dogs naturally experience enormous growth surges in the first year or two of their lives. It is now widely accepted that forcing even faster growth by feeding a highly concentrated, high-energy diet is dangerous for skeletal development, causing unsoundness and increased tendency to joint problems and injury. Being built primarily for speed, Borzoi do not carry large amounts of body fat or muscle, and therefore have a rather different physiology to other dogs of similar size (such as the Newfoundland, St. Bernard or Alaskan Malamute). Laboratory-formulated diets designed for a generic "large" or "giant" breed are unlikely to take the needs of the big sighthounds into account.
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.
