Borzoi Puppies: A Complete Week-by-Week Growth and Care Guide

Borzoi puppies are unlike any other breed you've likely raised. These Russian sighthounds grow at a staggering pace — a 10-pound pup at 8 weeks can eclipse 70 pounds by six months — and their sensitive, independent temperament demands a puppy-raising approach that accounts for their unique physiology and psychology. If you're preparing to bring home a borzoi puppy or are already navigating those first chaotic weeks, this guide gives you the breed-specific roadmap you won't find in generic puppy manuals.

Before we get into the details, a critical note: always consult your veterinarian before making decisions about your borzoi puppy's diet, vaccination protocol, or health concerns. Sighthounds, including borzoi, can respond differently to certain medications and anesthetics, and your vet should be your primary partner throughout puppyhood.

When Should You Bring Your Borzoi Puppy Home?

Responsible borzoi breeders typically release puppies between 8 and 10 weeks of age. While some breeders of giant or slow-maturing breeds hold puppies until 12 weeks, most borzoi breeders follow the 8-week standard. Bringing a puppy home before 8 weeks is strongly discouraged — the critical litter-socialization period (weeks 5–8) teaches bite inhibition, canine communication, and emotional regulation that you cannot replicate in a human household.

According to the American Kennel Club, puppies separated from littermates too early show higher rates of fear-based behaviors, reactivity, and difficulty with bite inhibition. For a breed as large and fast as the borzoi, solid bite inhibition is non-negotiable.

Borzoi Puppy Milestones: What to Expect Week by Week

Borzoi puppies pass through developmental windows rapidly. Understanding what's normal at each stage prevents unnecessary panic and helps you provide appropriate support.

Weeks 4–8 (Still With the Breeder)

• Weight: 5–12 lb (2.3–5.4 kg)
• Key development: Litter socialization, first solid foods, introduction to novel textures and sounds
• What the breeder should do: Early neurological stimulation (ENS), exposure to household sounds, first deworming (typically at 2, 4, 6, and 8 weeks), and first DHPP vaccine at 6–8 weeks
• Your role: Visit the litter at least twice before pickup. Handle the puppies, observe temperament differences, and ask the breeder about their socialization protocol

Weeks 8–12 (Home Transition)

• Weight: 12–22 lb (5.4–10 kg)
• Key development: Bonding with family, fear imprint period begins (~8–11 weeks), rapid growth spurts, high sleep needs (18–20 hours/day)
• Expect: Clingy behavior, startle responses to new stimuli, frequent naps, clumsy coordination as legs grow faster than body awareness
• Critical task: Begin positive-reinforcement socialization immediately — this window closes fast

Weeks 12–16

• Weight: 22–40 lb (10–18 kg)
• Key development: Increased confidence, testing boundaries, second fear period may begin (~12–14 weeks), teething discomfort starts
• Expect: Selective hearing, increased mouthing, sudden fear of previously familiar objects, growing independence
• Critical task: Maintain structured routines; avoid forcing the puppy past fears — use treats and patience instead

Weeks 16–24 (4–6 Months)

• Weight: 40–65 lb (18–29.5 kg)
• Key development: Peak teething (baby teeth fall, adult teeth erupt), adolescent energy surges, prey drive becomes more pronounced
• Expect: Destructive chewing, increased chasing behavior, possible regression in potty training, gangly "awkward phase" appearance
• Critical task: Provide structured outlet for energy (sniff walks, flirt pole sessions in fenced areas), puppy-proof your home thoroughly

Months 6–12

• Weight: 55–85 lb (25–38.5 kg) — males will trend toward the higher end
• Key development: Sexual maturity (spay/neuter typically recommended between 6–12 months for borzoi — discuss timing with your vet as some sighthound specialists prefer waiting until 12+ months for joint development), continued skeletal growth until 18–24 months
• Expect: Adolescent testing of recall, hormonal behaviors if intact, settling into adult personality traits
• Critical task: Continue formal training classes; borzoi are not a breed that "grows out of" training needs

Feeding Your Borzoi Puppy: Schedule and Portions

Borzoi puppies are deep-chested, fast-growing giant-breed dogs, which means their nutrition must be carefully managed to prevent developmental orthopedic diseases (DOD) like hip dysplasia and osteochondrosis. The key principle: slow and steady growth is safer than rapid growth.

Feed a large-breed puppy formula that meets AAFCO nutrient profiles for growth (specifically the "large breed" subset, which limits calcium and caloric density). Avoid high-protein or high-fat adult formulas during puppyhood — excess calories accelerate growth plate stress.

Vaccination Schedule for Borzoi Puppies

Your borzoi puppy's vaccination timeline follows the standard core-vaccine protocol, but timing matters enormously. Puppies receive maternal antibodies through colostrum that can neutralize vaccines given too early — which is why boosters are spaced at intervals until maternal immunity wanes.

Your veterinarian may also recommend Leptospirosis vaccination (non-core, lifestyle-dependent) if you live in an area with wildlife exposure or standing water access. Discuss vaccine protocols with your vet based on your specific risk profile.

Socialization Window: The Most Critical 11 Weeks of Your Borzoi's Life

The primary socialization period for puppies runs from approximately 3 to 14 weeks of age. For borzoi — a breed with strong prey drive, natural wariness of strangers, and a tendency toward shyness if under-socialized — this window is existential. Miss it, and you may spend years doing remedial counter-conditioning work.

Before your puppy is fully vaccinated, the American Veterinary Society of Animal Behavior (AVSAB) recommends that the benefits of early socialization outweigh the disease risk, provided you manage exposure carefully. Carry your puppy in public spaces, avoid dog parks and areas with unknown canine traffic, and arrange controlled playdates with fully vaccinated, temperament-tested dogs.

Borzoi Puppy Socialization Checklist (Weeks 8–14)

• Surfaces: Grass, gravel, wet pavement, metal grates, carpet, tile, wooden stairs, wobble boards
• People: Children (supervised), men with hats/beards, people in wheelchairs, delivery workers, people carrying umbrellas, people of different ethnicities and heights
• Sounds: Vacuum cleaner, thunderstorm recordings (low volume, paired with treats), doorbells, car horns, construction noise, fireworks recordings
• Animals: Vaccinated adult dogs (calm, predictable), cats (if household has them), livestock at a distance (important for prey-drive management)
• Handling: Paw handling, ear inspection, mouth opening, nail clipping practice, being lifted onto grooming tables, wearing a harness and coat
• Environments: Car rides (short, positive), pet-friendly stores (carried in a sling before vaccines complete), outdoor café patios, friends' homes, veterinary clinic (happy visits with no procedures)
• Objects: Flapping plastic bags, balloons (at a distance), bicycles, skateboards, lawn equipment

Rule of thumb: Aim for 5–10 novel positive experiences per day during this window. Keep sessions short (2–5 minutes each) and always pair new stimuli with high-value treats (boiled chicken, cheese, commercial training treats). If your puppy shows fear — tucked tail, cowering, refusal to take food — increase distance from the stimulus and reduce intensity. Never force exposure.

Potty Training Your Borzoi Puppy: Timeline and Troubleshooting

Realistic expectation: most borzoi puppies achieve reliable house-training between 4 and 6 months of age, though some individuals — especially males — may take until 8–9 months. Borzoi are not a breed that "just gets it" overnight. Their thin coats and low body fat make them cold-sensitive, which means they may resist going outside in rain, wind, or cold temperatures.

Potty Training Framework

Borzoi-specific troubleshooting:

• Cold-weather refusal: Invest in a fitted puppy coat (brands like Hurtta or Kurgo offer sighthound-specific cuts). Warm the puppy's paws with booties if snow or ice is a factor.
• Submissive urination: Common in young borzoi when greeting. Avoid leaning over or making direct eye contact during greetings. Crouch sideways, speak softly, and greet outdoors when possible.
• Regression at 4–6 months: Hormonal shifts and adolescent brain development can cause temporary setbacks. Return to more frequent breaks without punishment.

Never punish accidents. Rubbing a puppy's nose in urine or yelling creates fear of eliminating in front of you — not fear of eliminating indoors. Instead, interrupt mid-accident with a calm "oops," carry them outside immediately, and reward heavily for finishing outdoors. Clean indoor accidents with enzymatic cleaner (Nature's Miracle or Rocco & Roxie) to remove scent markers.

Crate Training Progression and Teething Survival

Crate Training Time Limits by Age

A crate is a management tool, not a storage unit. Borzoi puppies need substantial human interaction and cannot be crated for extended periods without risking anxiety and developmental delays.

• 8–10 weeks: Maximum 1–2 hours during the day (except overnight sleep, which may stretch to 3–4 hours with a middle-of-night potty break)
• 10–14 weeks: Maximum 2–3 hours during the day
• 3–5 months: Maximum 3–4 hours during the day
• 5–7 months: Maximum 4–5 hours during the day
• 7+ months: Maximum 5–6 hours during the day (with adequate exercise before and after)

For a breed that will reach 30+ inches at the shoulder, plan for a crate that will accommodate adult size — typically a 48-inch wire crate (MidWest iCrate or Frisco Heavy Duty). Use a divider panel to reduce the space while the puppy is small; too much room invites potty accidents in one corner.

Teething Timeline (3–6 Months)

Borzoi puppies begin losing deciduous (baby) teeth around 12–16 weeks, with the process completing by approximately 6–7 months. During this period, expect increased chewing, drooling, mild gum bleeding, and occasional irritability.

Safe chew strategies:

• Kong Classic (size Large or XL for borzoi): Stuff with a mixture of plain yogurt, mashed banana, and kibble, then freeze for 2–4 hours. The cold soothes gums.
• Benebone Puppy Wishbone: Nylon chew designed for teething puppies; softer than adult versions. Choose the "Puppy" line specifically.
• Frozen carrots or apple slices: Natural, low-calorie, and cold. Supervise to prevent choking on large pieces.
• Wet washcloth (frozen): Twist a clean washcloth, soak in water, freeze, and let puppy chew under supervision. Discard once frayed.

Avoid: Raw bones (splintering risk, bacterial contamination), antlers (tooth fracture risk — borzoi have powerful jaws even as puppies), and any chew toy smaller than the puppy's fist (choking hazard as they grow rapidly).

Common Borzoi Puppy Problems and Solutions

When Can Your Borzoi Puppy Go Outside and Meet Other Dogs?

This is one of the most common questions new borzoi puppy owners ask, and the answer balances disease risk against the closing socialization window.

Before full vaccination (before 16 weeks):

• Carry your puppy in a sling or carrier to public spaces — pet-friendly stores, outdoor markets, friends' homes
• Allow potty breaks in your own yard (assuming no unknown dogs have access)
• Arrange playdates with dogs you know to be fully vaccinated and temperamentally sound
• Avoid: Dog parks, pet store floors, communal grassy areas with unknown dog traffic, and any environment where parvovirus may be present

After final DHPP booster (typically 1–2 weeks post 14–16 week vaccine):

• Begin supervised visits to low-traffic dog areas
• Enroll in a puppy kindergarten class (most require proof of vaccination)
• Introduce leash walks in your neighborhood
• Continue avoiding dog parks until at least 6 months — the unpredictable, high-arousal environment is not appropriate for a developing borzoi

First-Year Cost Breakdown for a Borzoi Puppy

Borzoi are giant-breed dogs with correspondingly giant expenses. Here's a realistic 2026 budget for the first 12 months:

Emergency veterinary care is the wildcard. A single GDV (bloat) surgery can cost $3,000–$7,000+, and orthopedic injuries (common in fast-growing giant breeds) can exceed $5,000 per incident. Pet insurance with a high annual maximum ($10,000–$30,000) is a financially sound decision for borzoi owners.

Frequently Asked Questions

How often should I feed my borzoi puppy at 10 weeks?

At 10 weeks, feed 3–4 meals per day, totaling approximately 2–3 cups of large-breed puppy kibble daily. Split the total evenly across meals. Always provide fresh water and remove uneaten food after 15–20 minutes to establish a routine.

When will my borzoi puppy be fully potty trained?

Most borzoi puppies are reliably house-trained by 4–6 months, but some individuals — particularly males — may take until 8–9 months. Consistency, frequent outdoor breaks, and positive reinforcement for outdoor elimination are the most reliable methods. If your puppy is still having frequent accidents past 6 months, consult your vet to rule out urinary tract infections or anatomical issues.

What vaccines does my borzoi puppy need and when?

Core vaccines include DHPP (given at 6–8, 10–12, and 14–16 weeks) and Rabies (12–16 weeks, per local law). Non-core vaccines like Bordetella and Leptospirosis depend on lifestyle and regional risk. Your veterinarian will tailor the protocol to your puppy's specific needs.

How do I stop my borzoi puppy from biting and nipping?

Use the "ouch + withdraw" method: when teeth contact skin, say "ouch" calmly, turn away, and pause interaction for 10 seconds. Then redirect to an appropriate chew toy and reward engagement. Ensure your puppy gets adequate mental stimulation (sniff walks, puzzle feeders, training sessions) — bored puppies bite more. Never use physical punishment, which damages trust and can escalate to fear-based aggression.

Are borzoi puppies good with children?

Borzoi can be wonderful with respectful, calm children who understand canine body language. However, borzoi puppies are fragile (long legs, thin bones) and can be injured by rough handling. Conversely, a growing borzoi puppy can accidentally knock over a small child during play. Always supervise interactions and teach children to approach the puppy calmly, avoid tail-pulling, and let the puppy retreat to its crate when tired.

When can I start running with my borzoi puppy?

Not until growth plates close — typically between 14 and 18 months for borzoi. Before that, forced exercise (running alongside a bicycle, long jogs) risks joint damage. Stick to free-play in fenced areas, short sniff walks, and controlled puppy activity. Your vet can confirm growth plate closure via X-ray if you're unsure.
