Newfoundland — Adult Care

giant breed Low activity Average lifespan: 9 years

Care recommendations — Adult stage

In adulthood, the priority for a Newfoundland shifts toward maintaining an ideal body weight through portion-controlled meals and shorter, gentler walks and low-key play, since Newfoundlands are typically content with a calmer pace. The thick double coat sheds heavily and needs brushing two to three times a week to prevent matting, especially since it tends to trap moisture and debris. Pairing this with a yearly wellness exam and routine dental checks helps catch subtle changes early, even while the dog seems to be thriving.

⚠️ Watch for

In adult Newfoundlands, it's worth staying alert for early signs such as a bunny-hop gait, reluctance to jump or climb stairs, or stiffness after resting or front-leg lameness, a shortened stride, or reluctance to fully extend the elbow. These can be subtle at first, so raising them during an annual exam rather than waiting for them to worsen is a sensible approach given this breed's health background.

This information is general and educational — it isn't a substitute for advice from your veterinarian, who knows your individual dog's health history.
