Obesity, which can lead to arthritis and heart problems.

Feed a giant breed puppy formula designed for slow, steady growth.
Overfeeding can lead to rapid weight gain, increasing the risk of orthopedic issues.
Feed 3–4 smaller meals per day until 6 months, then gradually shift to 2 meals daily.
Avoid calcium supplements unless advised by a vet—imbalances can harm skeletal development.

Because of their thick, water-resistant double coats, Newfoundlands need to be thoroughly brushed at least once or twice a week—and every day during periods of significant shedding.
Maintaining skin health and controlling year-round shedding requires routine nail cutting, ear cleaning, addressing mats with slicker brushes and combs, and baths every two to three months.

Provide gentle exercise like walks and swimming; avoid jumping or high-impact activities.
Swimming is ideal for Newfoundlands—low-impact and a natural fit for their abilities.
Overexertion can damage growing joints, so limit rough play, stairs, or prolonged runs.
