Leonberger Puppy Weight Calculator

Hip and elbow dysplasia are common in giant breeds, so reputable breeders provide hip evaluations.
The breed also has a known risk of hereditary cataracts, progressive retinal atrophy, and an inherited bleeding disorder called von Willebrand's disease.
Most seriously, Leonbergers have a higher incidence of osteosarcoma (bone cancer) and a type of neuromuscular disease called Leonberger polyneuropathy.

These foods contain carefully balanced calcium and phosphorus levels to prevent developmental bone diseases.
Do not allow your puppy to become overweight, as extra pounds stress the growing skeleton.
Avoid free‑choice feeding and never supplement with additional calcium unless directed by your veterinarian.

Because of their thick, water-resistant double coat, Leonbergers require high-maintenance care.
To control the undercoat and avoid matting, they should be brushed two to three times a week (daily during significant, twice-yearly shedding).
A metal comb, undercoat rake, and slicker brush are essential tools. Taking a bath every six to eight weeks, cleaning your ears, and cutting your nails are all examples of regular grooming.

Provide moderate, low-impact exercise like leash walks and swimming. Avoid excessive running or jumping while bones are still forming.
Mental stimulation (e.g., training sessions, puzzle feeders) is equally important for this intelligent breed.
Limit stair climbing and rough play during growth phases to protect developing joints.
