Borzoi — Juvenile & Adolescent

The Borzoi is a breed that undergoes dramatic physical transformation during its juvenile and adolescent months. Between three and eighteen months of age, a Borzoi puppy will grow from a compact, somewhat clumsy youngster into a tall, elegant, and powerfully built sighthound. Growth in this breed is not always even or predictable; many Borzoi go through gangly, awkward phases where legs seem disproportionately long and the body appears narrow and underdeveloped. This is entirely normal and should not cause alarm.

Large and giant breeds like the Borzoi take significantly longer to reach full physical maturity than smaller dogs. While a Borzoi may reach close to its adult height by twelve months, filling out through the chest and developing mature muscle mass often continues well into the second year and sometimes beyond. Males in particular may not achieve their full physical presence until they are two to three years old. Monitoring growth through regular weigh-ins and body condition assessments helps ensure development is on track.

Rapid growth in large breeds carries specific orthopedic risks. The bones, joints, and connective tissues of a growing Borzoi are under considerable stress, and improper nutrition or excessive exercise during this period can contribute to developmental orthopedic diseases. Controlled growth through appropriate diet and managed activity levels is one of the most important things an owner can do to support long-term skeletal health.

Regular veterinary checkups during this growth phase allow for monitoring of joint development, dental eruption, and overall physical progress. Any signs of lameness, abnormal gait, or reluctance to move should be evaluated promptly, as early detection of orthopedic issues often leads to better outcomes. Your veterinarian can help you establish growth benchmarks appropriate for your individual Borzoi.

Feeding a growing Borzoi correctly is one of the most consequential decisions an owner will make during the juvenile period. Large and giant breed puppies have specific nutritional requirements that differ from those of smaller breeds, and the goal is to support steady, controlled growth rather than maximum growth rate. Overfeeding or providing a diet too high in calories and calcium can accelerate growth beyond what the developing skeleton can safely support, increasing the risk of conditions such as hypertrophic osteodystrophy and osteochondrosis.

A high-quality food formulated specifically for large-breed puppies is strongly recommended. These formulas are designed to provide appropriate calorie density and carefully balanced calcium-to-phosphorus ratios that support healthy bone development without promoting excessively rapid growth. Avoid supplementing with additional calcium unless specifically directed by your veterinarian, as excess calcium in large-breed puppies can be harmful rather than beneficial.

The transition from puppy food to adult food typically occurs between twelve and eighteen months for Borzoi, though the precise timing should be guided by your veterinarian's assessment of your individual dog's development. The switch should be made gradually over a period of seven to ten days, mixing increasing proportions of the new food with the old to minimize digestive upset. Some breeders and veterinarians recommend transitioning to an adult large-breed formula on the earlier side to help moderate the final stages of growth.

Borzoi can be somewhat finicky eaters compared to many other breeds, and maintaining a consistent feeding schedule with measured portions is important. Free-feeding is generally not recommended, as it makes it difficult to monitor intake and can contribute to uneven growth patterns. Two meals per day is appropriate for most juvenile Borzoi, and fresh water should always be available. Treats should be given in moderation and accounted for in the daily caloric total.

Adolescence in the Borzoi brings a unique set of behavioral changes that reflect the breed's independent and sometimes aloof nature. Between roughly four and twelve months of age, many Borzoi go through a period of testing boundaries, selective hearing, and increased independence that can challenge even experienced owners. This is a normal developmental phase, not a sign of a flawed temperament, and it requires patience and consistency to navigate successfully.

The Borzoi's sighthound heritage means that prey drive often intensifies during adolescence. A previously well-behaved puppy may suddenly become intensely focused on chasing squirrels, rabbits, or even blowing leaves. This instinct is deeply ingrained and should be managed through environmental control rather than punished. A securely fenced yard and leash walking in unfenced areas become non-negotiable safety measures during this period, as an adolescent Borzoi in pursuit of perceived prey can cover enormous distances at remarkable speed.

Fear periods are another hallmark of adolescent development. A Borzoi that previously seemed confident may suddenly become wary of new people, sounds, or situations. These fear periods are neurologically normal and typically pass within a few weeks if handled correctly. The key is to avoid forcing the dog into frightening situations while also not reinforcing fearful behavior with excessive coddling. Calm, matter-of-fact exposure with positive associations is the most effective approach.

Social dynamics may also shift during adolescence. A Borzoi that was previously easygoing with other dogs may begin to assert itself or become more selective about its canine companions. Same-sex aggression can emerge during this period, particularly in intact males. Monitoring interactions and providing structured socialization opportunities helps channel these natural social developments in a positive direction.

Training an adolescent Borzoi requires an understanding of the breed's unique temperament and learning style. Borzoi are intelligent but independent thinkers, and they do not respond well to harsh corrections, repetitive drills, or heavy-handed training methods. Positive reinforcement using high-value rewards, short and varied training sessions, and a sense of humor will yield far better results than attempts to impose rigid obedience through force or intimidation.

Recall is arguably the most critical training priority for a young Borzoi and also one of the most challenging to achieve reliably. The breed's powerful prey drive means that a Borzoi in pursuit mode may genuinely not hear or process a recall command. Building a strong recall foundation should begin early and be reinforced constantly with high-value rewards, but owners should understand that even a well-trained Borzoi may not be trustworthy off-leash in unfenced areas. Management and prevention are as important as training when it comes to keeping a sighthound safe.

Leash manners are another essential focus. An adult Borzoi is a large, powerful dog, and allowing pulling to become an established habit during the juvenile months creates a serious management problem later. Consistent leash training using reward-based methods should begin as soon as the puppy comes home and be practiced daily. Front-clip harnesses can be useful management tools while training is in progress.

Basic obedience commands such as sit, down, stay, and leave it provide a valuable communication framework and contribute to household harmony. However, expectations should be realistic. Borzoi are not naturally inclined toward the eager-to-please responsiveness of herding or sporting breeds, and a Borzoi that performs a command reliably at home may seem to forget it entirely in a stimulating outdoor environment. Patience, consistency, and realistic expectations are the cornerstones of successful Borzoi training.

Balancing the exercise needs of an adolescent Borzoi with the physical limitations imposed by ongoing skeletal development requires careful judgment. While Borzoi are athletic dogs built for speed and endurance, their growing bones and joints are vulnerable to damage from repetitive high-impact activity. The general guideline of five minutes of structured exercise per month of age, twice a day, provides a reasonable starting framework, but individual variation and the puppy's own signals should also guide decisions.

Free play in a safely enclosed area is one of the best forms of exercise for a growing Borzoi, as the puppy can self-regulate its activity level and rest when needed. Avoid forced running, especially on hard surfaces, and postpone activities like jogging alongside a bicycle or extended hiking until the dog has reached physical maturity. Jumping from heights, repetitive fetching on hard ground, and rough play with much larger dogs should also be moderated during the growth period.

Mental stimulation is just as important as physical exercise for an adolescent Borzoi. Puzzle toys, scent work, controlled exploration of new environments, and short training sessions all provide cognitive engagement that helps tire the mind without overtaxing the body. A mentally stimulated Borzoi is less likely to develop destructive behaviors born of boredom, which can become a significant issue in a breed with this much intelligence and energy.

As the Borzoi approaches physical maturity, exercise can gradually increase in intensity and duration. Lure coursing, a sport that channels the breed's natural prey drive and running ability, is an excellent outlet for adult Borzoi and can be introduced in a controlled manner once the dog is physically ready. Consulting with your veterinarian about appropriate exercise milestones for your individual dog is always a wise approach.

The decision about when or whether to spay or neuter a Borzoi is one that warrants careful discussion with your veterinarian and, ideally, your dog's breeder. Research in recent years has increasingly suggested that early spaying or neutering in large and giant breeds may carry health implications, including increased risk of certain orthopedic conditions and some cancers. These findings have led many veterinary professionals to recommend delaying the procedure in large breeds until after the dog has reached skeletal maturity.

For male Borzoi, skeletal maturity is typically reached between eighteen and twenty-four months of age. For females, the timeline is similar, though some veterinarians may recommend allowing the female to go through one or two heat cycles before spaying. The rationale for delayed sterilization is that the sex hormones play an important role in growth plate closure and overall musculoskeletal development, and removing them prematurely may result in disproportionate limb length and increased joint stress.

Living with an intact adolescent dog requires additional management considerations. Intact males may become more territorial, prone to roaming, and reactive to other intact males. Intact females will experience heat cycles approximately every six to twelve months, requiring careful containment and hygiene management. Owners who choose to delay sterilization must be prepared for these realities and committed to preventing unplanned breeding.

Ultimately, the spay/neuter decision should be individualized based on the dog's health, living situation, and the owner's ability to manage an intact animal responsibly. Discuss the current research and your specific circumstances with your veterinarian to arrive at a timeline that best supports your Borzoi's long-term health and well-being.

Continued socialization during the juvenile and adolescent period is essential for producing a confident and well-mannered adult Borzoi. While the most sensitive socialization window closes around twelve to fourteen weeks of age, the experiences and exposures that occur throughout the first year and beyond continue to shape the dog's temperament and behavior. A Borzoi that is sheltered from the world during adolescence may develop lasting fearfulness or reactivity that is much harder to address in adulthood.

Exposure to a wide variety of people, including individuals of different ages, appearances, and mannerisms, helps build the Borzoi's comfort with human diversity. The breed can be naturally reserved with strangers, and positive early experiences with unfamiliar people help prevent this reserve from becoming problematic shyness or suspicion. Always allow the Borzoi to approach new people at its own pace rather than forcing interactions, and reward calm, confident behavior generously.

Socialization with other dogs should be carefully managed during adolescence. Positive experiences with well-mannered dogs of various sizes and temperaments build social skills and confidence, while negative encounters with aggressive or overly rough dogs can have lasting detrimental effects. Dog parks can be unpredictable environments, and many Borzoi owners find that organized playgroups with known, compatible dogs provide a safer and more productive socialization experience.

Environmental exposure is equally important. Car rides, visits to pet-friendly stores, walks in different neighborhoods, and exposure to various surfaces, sounds, and situations all contribute to a well-rounded Borzoi. Urban environments, in particular, present stimuli that a country-raised Borzoi may never encounter otherwise. Each new experience should be introduced at a pace the dog is comfortable with, always pairing novel stimuli with positive associations to build lasting confidence.
