Leonberger (Leo, Gentle Lion)

Weighing 90–170 lb (40.8–77.1 kg) and standing 26–31 in (64.8–80 cm) tall, the Leonberger is a giant representative of the Working Group. AKC registration statistics place it at #99 in popularity. Originally from Germany, the breed carries that working heritage in its build and temperament. Many owners just call them Leos. As with most breeds, males occupy the top of the size range.

How long do Leonbergers live? Based on published breed data, a typical lifespan is 7–8 years. Lifespan is influenced by size, since smaller dogs generally outlive larger ones, alongside genetics, body weight, dental care and regular veterinary checkups. Keeping a Leonberger lean, exercised and current on preventive care is the most practical way to reach the upper end of that range. On the size-related aging curve, giant breeds like this one age at a moderate pace.

Apartment suitability is high — size and temperament make compact living realistic. Shedding is heavy. Expect visible hair on clothing and furniture, and brush several times a week. This coat is a commitment, involving regular professional grooming and near-daily brushing for the fuller styles. No low-shedding claim applies here. Allergy sufferers should spend time with the breed before committing.

Expect medium energy — regular walks and a bit of active play go a long way. Eager to please and quick to learn, this breed makes training one of the genuine joys of ownership. This breed is known as an excellent family dog that generally adores children. Canine housemates generally work out fine, though same-sex pairs can need more management.

Every number on this page is meant to be used, not just read. The calculators below start from this breed's 59 kg average weight, which in our 152-breed database sits heavier than 97% of breeds, and turn it into daily food portions, crate sizing and first-year budget estimates. That percentile is not trivia. Food bills, gear sizing and medication dosing all track body weight. Data comes from the AKC breed profile cited below, and breed-specific health risks are exactly why comparing pet insurance early, while your dog is young and healthy, pays off.
