Overview

Lion-like German giant — calm, devoted, and a heavy shedder.

The Leonberger is a giant breed in the Working group, typically standing 25.5–31.5 in and weighing 90–170 lbs. Expect a lifespan of 7 years with good preventive care. Personality is best described as friendly, gentle, patient.

Breed history & origin

The Leonberger traces its origins to Multiple regions historically. Its original purpose — guarding, draft work, and rescue — shaped almost every physical and temperamental trait still visible in the breed today.

As a giant member of the Working group, the Leonberger was selectively bred for biddability and quick learning, steady temperament and an even pace. Modern owners describe them as friendly, gentle, patient — qualities deeply rooted in that working heritage.

The breed is recognised by all major kennel clubs in the Working group, with a written standard codifying its silhouette, gait, and temperament.

Today the Leonberger thrives as a working dog and family guardian. It remains one of the more recognisable breeds at North American dog shows and in homes across Canada and the United States, where its combination of friendly and family-suitability continues to draw new owners every year.

Like every purebred, the Leonberger carries genetic risks tied to its small founding gene pool. Conscientious modern breeders screen for the conditions listed in the health section below and breed for longevity, structural soundness, and stable temperament — the three pillars of a responsibly preserved breed.

Temperament

Leonbergers are friendly, gentle, patient. With early socialization and positive-reinforcement training in the critical 8–16 week window, they grow into well-adjusted adults that fit a wide range of households.

Exercise & activity

Adult Leonbergers need 30–60 minutes/day, split between leashed walks and off-leash play. Under-exercised dogs of this breed are the #1 source of behaviour complaints — chewing, barking, and pulling.

Grooming & shedding

Leonbergers are high-maintenance coats. Plan on daily brushing and a professional groom every 4–6 weeks.

Heavy shedder. Expect hair on furniture and clothes year-round, with two heavy blow-outs per year.

Nutrition guide

Feed a high-quality large-breed puppy formula with controlled calcium and slow growth. Leonberger puppies thrive on 3 measured meals per day until 6 months, then 2 meals. Look for AAFCO statements naming "growth" or "all life stages," and skip filler-heavy grocery brands.

Puppy nutrition

Feed an AAFCO-approved large-breed puppy formula. 3 meals/day until 6 months, then 2/day.

Adult nutrition

Adult Leonbergers do well on a high-quality kibble (≥ 25% protein, ≤ 15% fat) split into two meals. Free-feeding is the #1 cause of obesity in this breed.

Senior nutrition

From age 6, transition to a senior formula with glucosamine/chondroitin and reduced calories.

Daily calories (adult)

1,800–2,500 kcal/day

Common allergies: Most common triggers in this breed: chicken, beef, dairy, wheat. A novel-protein diet (duck, salmon, venison) helps if itching or GI issues persist.

Never feed:
  • Grapes & raisins
  • Chocolate
  • Onions & garlic
  • Xylitol (peanut butter labels!)
  • Cooked bones
  • Macadamia nuts

Training guide

Housebreaking

Crate-train from day 1. Leonberger puppies can hold their bladder roughly (age in months) hours — set a timer and take them out after every nap, meal, and play session.

Crate training

Use a crate just large enough to stand and turn around. Never use it as punishment. Most Leonbergers accept the crate within 2 weeks with kong-and-meal pairing.

Obedience

Leonbergers are eager learners — start sit, down, place, and recall in week 1. Aim for 5-minute training reps, 3–5x per day.

Socialisation

Critical window is 8–16 weeks. Aim for 100 new people, 50 new dogs, and 25 new environments before 4 months — vaccinated, controlled, positive exposures only.

Advanced training

Ready for AKC Canine Good Citizen by 12 months, then trick titles, agility, rally, or scent-work.

Common mistakes to avoid
  • ×Skipping puppy class because the dog ‘seems fine’
  • ×Using punishment for fear-based behaviour (escalates it)
  • ×Repeating the cue word — say it once, then enforce
  • ×Free-feeding (kills food motivation for training)
