St. Bernard Puppies: Finding Reputable Breeders & Your
St. Bernard puppies, from finding ethical breeders to feeding schedules, vaccinations, potty training, and first-year costs.
Finding Ethical St. Bernard Puppies: What Reputable Breeders Look Like
Bringing a St. Bernard puppy into your home is a commitment that spans 8–10 years and thousands of dollars. Before you fall in love with a litter photo online, understanding what separates a responsible St. Bernard breeder from a backyard operation is the single most important decision you'll make. The AKC Breeder of Merit program and the Saint Bernard Club of America's breeder referral network are your best starting points.
Responsible St. Bernard breeders will willingly provide:
- OFA (Orthopedic Foundation for Animals) health clearances for both parents — hips, elbows, heart (echocardiogram), and eyes (CERF exam)
- DNA test results for degenerative myelopathy (DM) and ichthyosis
- A written contract with a take-back clause, spay/neuter requirements for pet-quality puppies, and a health guarantee covering genetic conditions for at least 2 years
- Proof of early socialization — puppies raised in-home with exposure to household sounds, surfaces, and handling (not isolated in outdoor kennels)
- References from previous puppy buyers and their veterinarian
When should you bring your puppy home? No earlier than 8 weeks of age — and many reputable St. Bernard breeders prefer to keep puppies until 10–12 weeks. Giant breeds mature slowly, and those extra weeks with the breeder provide critical littermate socialization that reduces bite inhibition problems later. The AVMA recommends puppies remain with their mother and littermates for a minimum of 8 weeks.
St. Bernard Puppy Milestones: Week-by-Week Development Timeline
St. Bernards grow at a staggering rate — a puppy that weighs 1.5 pounds at birth can reach 140+ pounds within 18 months. Understanding what to expect at each developmental stage helps you prepare your home, training plan, and veterinary schedule.
| Age Range | Typical Weight | Key Milestones | What You Should Do |
|---|---|---|---|
| Weeks 4–8 | 5–15 lb (2–7 kg) | Eyes/ears fully functional; deciduous teeth erupting; learning bite inhibition from littermates; first solid food; first deworming | If visiting the litter: handle puppy daily, expose to varied textures. Breeder should begin ENS (Early Neurological Stimulation) |
| Weeks 8–12 | 15–30 lb (7–14 kg) | Primary socialization window opens; fear periods begin (~8–10 weeks); first DHPP vaccine; can learn name recognition and basic sit | Begin structured socialization checklist; establish feeding/crate/potty routines; first vet visit within 48 hours of pickup |
| Weeks 12–16 | 30–50 lb (14–23 kg) | Socialization window closing (~14 weeks); second fear period (~14–16 weeks); rapid growth phase; crate training solidifies | Enroll in puppy kindergarten (post-vaccine); begin leash training with harness; increase exercise to 20 min/day structured walks |
| Weeks 16–24 | 50–85 lb (23–39 kg) | Teething peaks (3–6 months); testing boundaries; sexual maturity approaching; spay/neuter discussion with vet | Provide appropriate chew outlets; reinforce all training with consistency; increase daily exercise to 30–40 min; schedule spay/neuter (typically 6–12 months for giant breeds) |
| Months 6–12 | 85–130 lb (39–59 kg) | Adolescent regression in training; adult teeth fully in; growth rate slows; joints still developing (growth plates open until ~18–24 months) | Continue obedience classes; avoid forced running/jumping on hard surfaces; transition to large-breed adult food at 12–18 months per vet guidance; maintain 45–60 min daily exercise |
St. Bernard Puppy Feeding Schedule: Portions by Age and Weight
Feeding a giant breed puppy correctly is one of the most consequential health decisions you'll make. Overfeeding causes skeletal deformities that no surgery can fully correct. Use a large-breed puppy formula (such as Purina Pro Plan Large Breed Puppy, Royal Canin Giant Puppy, or Hill's Science Diet Large Breed Puppy) and measure every meal.
| Age | Meals Per Day | Approx. Daily Amount (Dry Kibble) | Notes |
|---|---|---|---|
| 8–12 weeks | 3–4 | 2.5–4 cups/day (divided across meals) | Moisten kibble with warm water if puppy struggles to chew; always provide fresh water |
| 12–16 weeks | 3 | 4–5.5 cups/day | Monitor body condition score (BCS) — should be 4–5/9; adjust up or down based on individual metabolism |
| 4–6 months | 2–3 | 5–7 cups/day | Can transition to 2 meals/day at 6 months; use slow-feeder bowls to prevent gulping (bloat risk) |
| 6–12 months | 2 | 6–9 cups/day | Males will eat toward the higher end; do NOT increase food to accelerate growth |
How often should you feed your puppy at each age? The schedule above gives precise meal frequency. The most common mistake St. Bernard owners make is free-feeding (leaving food out all day). This not only promotes rapid growth and joint damage but also makes potty training unpredictable since you can't anticipate when your puppy needs to eliminate.
Potty Training Your St. Bernard Puppy: Realistic Timeline & Log Template
When will your puppy be fully potty trained? For a St. Bernard, expect 4–8 months of consistent effort before you can consider your puppy reliably house-trained — and occasional accidents may continue through 12 months. Giant breed puppies have proportionally smaller bladders relative to their body size during early growth, and their physical immaturity means sphincter control develops more slowly than in smaller breeds.
Here is a realistic potty training timeline:
- 8–12 weeks: Accidents every 1–2 hours. Take puppy outside every 30–45 minutes while awake, immediately after meals, naps, and play sessions. Expect 10–15 outings per day.
- 12–16 weeks: Bladder control improving to 1.5–2.5 hours between outings. Puppy may start signaling (whining, circling, going to the door).
- 4–6 months: Can hold 3–4 hours during the day. Overnight control of 6–8 hours typically established. Still supervise closely indoors.
- 6–8 months: Most St. Bernards are reliably house-trained if you've been consistent. Continue praising outdoor elimination.
Track each outing in a notebook or phone app with these columns:
• Time (e.g., 7:15 AM)
• Trigger (woke up / after meal / after play / scheduled)
• Result (pee / poop / both / nothing)
• Accidents (time, location, what happened before)
This data reveals your puppy's personal elimination pattern within 7–10 days, allowing you to anticipate needs rather than react to accidents.
Troubleshooting common potty training problems:
- Submissive/excitement urination: Common in young St. Bernards. Don't scold — it's involuntary. Greet calmly, take outside immediately upon arriving home, and avoid direct eye contact during greetings until puppy is calm.
- Nighttime accidents: Set an alarm for one overnight potty break (around 2–3 AM) until puppy consistently sleeps 7+ hours dry. Reduce water access 1.5 hours before bedtime.
- Returning to same indoor spot: Clean accidents with an enzymatic cleaner (Nature's Miracle or Rocco & Roxia) — regular household cleaners don't break down uric acid crystals, and your puppy can still smell the marker.
Vaccination Schedule for St. Bernard Puppies
What vaccines does your puppy need and when? The following schedule follows the AAHA Canine Vaccination Guidelines, which your veterinarian will customize based on your puppy's health status and regional disease risk.
| Age | Vaccine(s) | Type | Notes |
|---|---|---|---|
| 6–8 weeks | DHPP (Distemper, Hepatitis/Adenovirus, Parainfluenza, Parvovirus) — Dose 1 | Core | Often administered by breeder before pickup; confirm with records |
| 10–12 weeks | DHPP — Dose 2; Bordetella (optional, recommended if attending puppy classes) | Core + Lifestyle | Puppy is NOT fully protected yet — avoid high-traffic dog areas |
| 14–16 weeks | DHPP — Dose 3 (final puppy booster); Rabies (required by law in most states) | Core | Full protection approximately 2 weeks after final DHPP dose (~16–18 weeks) |
| 12–16 months | DHPP booster; Rabies booster (1-year or 3-year depending on local law) | Core | After this, DHPP typically every 3 years; discuss titer testing as alternative with your vet |
When can your puppy go outside and meet other dogs? This is the tension every St. Bernard puppy owner faces: the critical socialization window closes around 14–16 weeks, but full vaccine protection isn't achieved until approximately 18 weeks. The AVMA and the American Veterinary Society of Animal Behavior (AVSAB) recommend that puppies begin socialization BEFORE full vaccination — the behavioral risk of under-socialization (fear, aggression, anxiety) outweighs the disease risk when managed properly.
Safe socialization before full vaccination:
- Carry your puppy in a sling or cart through shopping centers, parks, and outdoor cafés
- Arrange playdates with fully vaccinated, known-healthy adult dogs in private yards
- Attend puppy kindergarten classes that require proof of at least one DHPP dose and maintain sanitized floors
- AVOID dog parks, pet store floors, and unknown dog feces until 2 weeks after the final DHPP booster
Socialization Checklist: Making the Most of the 3–14 Week Window
The primary socialization period (approximately 3–14 weeks) is the single most important developmental window for your St. Bernard puppy. Experiences during this period literally shape neural pathways that determine how your dog responds to the world for life. A 140-pound adult St. Bernard who is fearful of strangers, loud noises, or veterinary handling is not just a behavioral challenge — it's a safety concern.
Weekly Socialization Goals (Weeks 8–14):
- People: Meet 10+ new people per week — different ages, ethnicities, body sizes, people wearing hats/sunglasses/hoodies, children (supervised), people using wheelchairs or crutches
- Surfaces: Walk on grass, gravel, metal grates, wet pavement, carpet, tile, tarps, wobble boards
- Sounds: Vacuum cleaner (start distant, gradually closer), thunderstorms (play recordings at low volume), fireworks audio, doorbells, car engines, hair dryers
- Handling: Daily — touch ears, open mouth, examine paws, lift tail, gently restrain for 10 seconds, simulate nail trimming with a Dremel vibration (without cutting)
- Objects: Umbrellas opening, balloons, trash cans, bicycles, skateboard, shopping carts, flags
- Environments: Car rides (short trips ending in fun destinations), outdoor café patios, hardware stores (dog-friendly ones), veterinary clinic ("happy visits" with treats only, no procedures)
- Other animals: Calm adult dogs (vaccinated), cats (if applicable, supervised), livestock if rural
Keep every experience positive. If your puppy shows fear, increase distance from the stimulus and offer high-value treats (boiled chicken, cheese). Never force a fearful puppy to approach something — this creates lasting negative associations. Pair novel experiences with food to build positive conditioned emotional responses.
Crate Training Progression & Teething Relief (3–6 Months)
A properly crate-trained St. Bernard is safer, calmer, and easier to manage during the destructive adolescent phase. Start crate training the day you bring your puppy home, but respect age-appropriate time limits.
| Age | Max Daytime Crate Time | Max Overnight Crate Time | Crate Size Recommendation |
|---|---|---|---|
| 8–10 weeks | 30–60 minutes | 3–4 hours (set alarm for potty break) | 36-inch wire crate with divider panel |
| 10–14 weeks | 1–2 hours | 5–6 hours | 36-inch crate, move divider as puppy grows |
| 4–6 months | 2–3 hours | 7–8 hours | Transition to 42-inch or 48-inch crate |
| 6–12 months | 3–4 hours | 8 hours | 48-inch or 54-inch crate (adult St. Bernards need 48–54 inch) |
Crate training method: Feed all meals inside the crate with the door open. Toss high-value treats (Kong stuffed with frozen peanut butter) inside. Gradually close the door for increasing durations while you're present, then step out of sight for short periods. Never use the crate as punishment.
Teething timeline and relief strategies (3–6 months):
St. Bernard puppies begin losing deciduous teeth around 12–16 weeks, with adult teeth fully erupted by 6–7 months. During this period, your puppy will chew everything. Redirect to appropriate outlets:
- Frozen Kongs: Stuff with plain yogurt, pumpkin puree, or soaked kibble and freeze for 4+ hours. The cold numbs sore gums.
- Benebone Wishbone or Nylabone Dura Chew: Sized for dogs 50+ lb (even though your puppy isn't there yet, they'll grow into it).
- Wet washcloth twist: Wet a clean washcloth, twist into a rope shape, freeze, and supervise chewing sessions (remove if puppy tears off pieces).
- Yak cheese chews: Long-lasting and digestible — supervise to prevent choking on small end pieces.
Common St. Bernard Puppy Problems & Breed-Specific Solutions
How do you stop puppy biting and nipping? St. Bernard puppies are mouthy — this is normal breed behavior, not aggression. Their size makes nipping feel more alarming than it is with smaller breeds, but the solution is the same: teach bite inhibition through consistent feedback.
- Redirect: When puppy teeth touch skin, immediately offer an appropriate chew toy. Praise enthusiastically when they chew the toy instead.
- Withdraw attention: If redirection fails, stand up, cross your arms, and turn away for 10–15 seconds. No talking, no eye contact. Resume play only when puppy is calm.
- Never use physical punishment: Holding the mouth shut, alpha rolls, or hitting creates fear and can escalate to defensive biting. Positive reinforcement and time-outs are more effective and build trust.
- Provide sufficient exercise: A tired puppy is a less mouthy puppy. At 8–12 weeks, 10–15 minutes of structured play (tug with rules, fetch in a hallway, training games) 3–4 times daily reduces nipping significantly.
Other breed-specific puppy challenges:
- Destructive chewing: St. Bernards have powerful jaws. Puppy-proof by removing shoes, remote controls, and electrical cords from reach. Provide a rotation of 5–7 approved chew toys to prevent boredom.
- Whining/howling when crated: Ensure puppy has been exercised and has eliminated before crating. Cover the crate with a light blanket to reduce visual stimulation. If whining persists after 15–20 minutes, take puppy out on leash for a quick potty trip (boring, no play), then return to crate.
- Jumping up: A 60-pound adolescent St. Bernard jumping on guests is dangerous. Teach "four on the floor" from day one: reward all four paws on the ground with treats and attention; turn away when puppy jumps.
- Counter-surfing: St. Bernards are tall enough to reach countertops by 5–6 months. Never leave food unattended. Teach "leave it" using positive reinforcement with increasing difficulty levels.

Frequently Asked Questions About St. Bernard Puppies
When should I bring my St. Bernard puppy home?
No earlier than 8 weeks, and many experienced St. Bernard breeders prefer 10–12 weeks for giant breeds. The additional time with the breeder supports bite inhibition learning, early socialization, and ensures the puppy has received its first DHPP vaccine. If a breeder offers you a puppy younger than 8 weeks, that is a significant red flag.
How often should I feed my St. Bernard puppy?
At 8–12 weeks: 3–4 meals per day (2.5–4 cups total daily). At 12–16 weeks: 3 meals per day (4–5.5 cups total). At 4–6 months: 2–3 meals per day (5–7 cups total). At 6–12 months: 2 meals per day (6–9 cups total). Always use a large-breed puppy formula and measure precisely — free-feeding giant breed puppies causes skeletal damage.
When will my St. Bernard puppy be fully potty trained?
Expect 4–8 months of consistent training before reliable house-training. Some St. Bernards take up to 12 months. Consistency in schedule, crate training, and positive reinforcement for outdoor elimination are the keys. If accidents suddenly increase after a period of success, consult your veterinarian to rule out a urinary tract infection.
What vaccines does my St. Bernard puppy need and when?
Core vaccines include DHPP (Distemper, Hepatitis, Parainfluenza, Parvovirus) at 6–8 weeks, 10–12 weeks, and 14–16 weeks, plus Rabies at 14–16 weeks. Lifestyle vaccines like Bordetella may be recommended for puppy class attendance. Your veterinarian will determine the exact protocol based on your puppy's health and local disease prevalence.
How do I stop my St. Bernard puppy from biting and nipping?
Redirect to appropriate chew toys every time teeth touch skin. If biting continues, withdraw attention for 10–15 seconds (stand up, turn away, no eye contact). Provide adequate exercise and mental stimulation — a bored, under-exercised puppy mouths more. Never use physical punishment, which creates fear and worsens the behavior. Bite inhibition typically improves significantly by 5–6 months as adult teeth come in.
When can my St. Bernard puppy go outside and meet other dogs?
You can and should begin socialization before full vaccination. Carry your puppy in public spaces, arrange playdates with known vaccinated dogs, and attend puppy classes that require at least one DHPP dose. Avoid dog parks, pet store floors, and areas with unknown dog waste until 2 weeks after the final DHPP booster (approximately 18 weeks of age). Consult your veterinarian for guidance specific to your area's parvovirus risk level.
