Leonberger
LAY-on-bur-gur
Gentle, Playful, Friendly, Patient. Originally bred for bred to resemble a lion; water rescue and farm work.
An adult Leonberger weighs 110-170 lbs (male) or 90-140 lbs (female), needs 1,360-2,910 calories daily, and lives 7-9 yrs. Giant breeds grow slowly and need careful nutrition management during their extended puppyhood. The breed's primary health watch is hip dysplasia. All numbers below come from AKC breed standards and NRC 2006 veterinary nutrition formulas.
Nutrition and feeding
A typical adult Leonberger needs 1,360 to 2,910 calories per day. An average male (140 lbs / 63.5 kg) needs around 2,200 kcal; a female (115 lbs / 52.2 kg) roughly 1,900 kcal. These estimates use the vet-standard RER/MER formula.

Health profile
The Leonberger's greatest vulnerability is the one shared by all giant breeds: a short lifespan. At 7-9 years average, every year counts, and proactive health screening is the best way to maximize them. Osteosarcoma (bone cancer) is disproportionately common in the breed, and the size that makes them magnificent also puts enormous stress on their joints and cardiovascular system. Life expectancy is 7 to 9 years.
Exercise and activity
Moderate; 30-60 minutes daily. They enjoy swimming (webbed feet make them natural water dogs) and moderate hiking. Working breeds like the Leonberger were developed for specific physical tasks. They need purposeful activity, not just wandering around a yard. Structured exercise with clear tasks, such as carrying a dog pack on hikes, pulling a cart, or advanced obedience training, satisfies their need to work.
Care and traits
Leonbergers have a long, water-resistant double coat with lion-like mane coat. Origin: Germany (Leonberg).
Bred by Heinrich Essig to look like the lion on the Leonberg city crest. Nearly extinct after both World Wars; only 5 Leonbergers survived WWII. Their webbed feet make them excellent swimmers, and they're used in water rescue in some countries.
Grooming is a significant time commitment with this breed. Plan for daily brushing sessions and professional grooming every 4-6 weeks. Skipping grooming leads to mats, skin irritation, and potential infection underneath tangled coat.
Heavy shedding is a reality with this breed. Expect dog hair on furniture, clothing, and in every corner of your home. A good vacuum, lint rollers, and acceptance are your best tools. Shedding typically increases during seasonal coat changes in spring and fall.
Living space matters for a breed this size. They need room to move without knocking things over, and many giant breeds prefer cool environments. Heat tolerance is limited; monitor closely in warm weather. Elevated food and water bowls may improve comfort during meals.

Frequently asked questions
Adult Leonbergers need 1,360 to 2,910 calories per day; a 140-pound male requires roughly 2,200 kcal, a 115-pound female about 1,900 kcal. At these volumes, food cost is a real consideration: budget $150-250/month depending on the brand. During the growth phase (up to 18-24 months), feed a large-breed puppy formula specifically designed for slow, steady growth; standard puppy food promotes growth rates that can damage developing joints in giant breeds.
Males: 120-170 lbs (54.4-77.1 kg). Females: 100-135 lbs (45.4-61.2 kg). Leonbergers are supposed to be large but not fat; their size should come from bone and muscle, not excess weight. Because they're already carrying enormous structural loads, even 10 extra pounds significantly accelerates joint wear. Body condition is harder to assess visually on giant breeds, so use the rib test and watch for loss of waist definition from above.
The Leonberger's most notable breed-specific vulnerability is hip dysplasia. Hip and elbow dysplasia affect many giant breeds, and Leonbergers are no exception. Bloat (GDV) is a life-threatening emergency that giant, deep-chested breeds face; feed multiple smaller meals and avoid exercise after eating. The breed's average lifespan of 7-9 years means every health screening and preventive measure counts.
Most Leonbergers are content with 30 to 60 minutes of daily exercise. Swimming is the best exercise for Leonbergers; full-body conditioning without joint impact. Avoid high-impact activities like running on pavement, especially in dogs under 2 years old. They're not couch potatoes despite their calm temperament; they need regular movement to maintain the muscle mass that supports their massive skeleton.
