In short

The Leonberger is a Working breed from Germany, created in the 1840s in the town of Leonberg as a lion-like family and farm dog; adults weigh about 90–170 lbs and live 7–9 years. It is a calm, gentle giant with a heavy coat and known inherited nerve diseases, so DNA testing matters.

Is it right for you?

A great match if you…

  • want a calm, kid-friendly gentle giant
  • love swimming and outdoor walks
  • can handle hair, drool and mud

Think twice if you…

  • live in a hot climate or small apartment
  • want a tidy, low-shedding dog
  • can't face a 7–9 year lifespan

What sets it apart

  1. 01

    Lion-like mane

    Males carry a dramatic mane, which means heavy shedding and lots of brushing.

  2. 02

    Black mask

    A black face mask over a lion-yellow to red-brown coat is a breed hallmark.

  3. 03

    Webbed feet

    Leos love water, so expect a wet, muddy dog after any walk near a pond.

01

Personality

Leonbergers are calm, gentle and devoted, happiest in the middle of family life. They are steady in public and patient at home. Expect drool, mud and hair, plus a dog that wants to be included in everything.

With kids

Excellent with kids and famously patient. Size still means supervision with toddlers.

With other pets

Usually good with dogs and cats, especially when raised together.

With strangers

Friendly and confident, but watchful. Their size alone deters most strangers.

Alone time

Very family-focused and dislike long isolation. Shorter absences work once they are mature.

02

Training

Leonbergers are intelligent and willing but can be sensitive, so calm, positive training works best. Early manners matter because they grow fast.

  1. How often

    2–3 sessions a day of 5–10 minutes each, ending each one on a win.

  2. Socialize early (8–16 weeks)

    Between 8–16 weeks, focus on new people, places and handling, plus grooming tolerance. A confident Leo is easy; a fearful one this size is not.

  3. Self-control

    Loose-leash walking and calm greetings matter most for a dog of this weight. Reward slack leash and sit-to-greet every time.

  4. What it works for

    Food and praise both work well. Use small, high-value pieces within 10% of daily calories; freeze-dried liver is one option.

03

Exercise

Leonbergers need steady daily walks, hikes and swimming, not intense running. They enjoy carting and water work.

Exercise a day 60–90 min
CouchModerateAthlete

Good outlets

  • Swimming
  • Carting or drafting (adults only)
  • Long walks and hikes

Brain work

  • Water retrieves
  • Scent games
  • Obedience and trick classes

Best home

House with a yard suits best; struggles in heat and small apartments.

Watch for Avoid heavy exercise while puppies grow and during heat, and avoid exercise around meals because of bloat risk.

04

Feeding

Adult maintenance for a typical Leonberger (90–170 lbs) lands around 1,800–2,925 kcal a day. Feed to body condition, not the bag's chart alone, and keep treats inside the 10% rule.

The treat limit is the 10% rule for every treat combined. Saylor's liver is suggested at about 2% of daily calories, as a small topper: liver is very rich in vitamin A, so it should not become a staple. Check with your vet if your dog has a health condition or a special diet.

Health & grooming

Leonberger polyneuropathy, LEMP, hip and elbow dysplasia, bone cancer and bloat are the main concerns. Choose a breeder who DNA-tests and screens hips, elbows and eyes.

Watch forAsk the breeder or vet forWhen
Leonberger polyneuropathy LPN1 and LPN2 DNA tests Once, in breeding dogs
Leukoencephalomyelopathy (LEMP) LEMP DNA test Once, in breeding dogs
Hip and elbow dysplasia OFA or PennHIP hip and OFA elbow evaluations Once, in breeding dogs (ask the breeder)
Inherited eye disease Eye exam by a veterinary ophthalmologist (CAER) Yearly in breeding dogs
Autoimmune thyroiditis OFA thyroid panel From 12 months; repeat periodically

Official health tests for breeding dogs

The OFA's CHIC program asks Leonberger breeders to test for these. Ask to see the results before you buy a puppy.

  • Hip evaluation
  • Elbow evaluation
  • Eye exam (ophthalmologist)
  • Leonberger Polyneuropathy (LPN1)
  • Leonberger Polyneuropathy (LPN2)
  • Leonberger Polyneuropathy (LPN3)
  • Thyroid panel
  • Leukoencephalomyelopathy (LEMP)

Also recommended

  • Heart exam
  • DNA sample banked with CHIC

Grooming Heavy, with big seasonal sheds

Brush 2–3 times a week and daily during sheds, especially the mane and britches. Trim nails every 2–3 weeks, check ears weekly, brush teeth several times a week and wipe drool as needed.

History

  1. 1840s

  2. 1914–1945

    Wartime decline

Questions owners ask

Are Leonbergers easy to train?

Fairly easy. Leonbergers are smart and willing, and they respond well to calm, positive training. Start manners early because they grow fast.

Are Leonbergers good with kids and other pets?

Yes. They are famously gentle with kids and usually good with other dogs and cats, though their size calls for supervision.

How much exercise does a Leonberger need?

About 60–90 minutes a day of walks, hikes and swimming. Avoid intense running while puppies grow.

Do Leonbergers shed?

Yes, heavily. The thick double coat sheds year-round with big seasonal sheds, so brush 2–3 times a week.

What health problems do Leonbergers have, and how long do they live?

Polyneuropathy, LEMP, hip and elbow dysplasia, bone cancer and bloat are the main concerns. Leonbergers typically live 7–9 years.

Is a Leonberger good for apartments or first-time owners?

Not for apartments. First-time owners can do well with the gentle temperament if prepared for size, hair and costs.
