Newfoundland

Weighing 100–150 lb (45.4–68 kg) and standing 26–28 in (65.4–71.1 cm) tall, the Newfoundland is a giant representative of the Working Group. Among AKC-registered breeds it sits at #47 by popularity. The breed traces its roots to Canada. As with most breeds, males occupy the top of the size range.

How long do Newfoundlands live? Based on published breed data, a typical lifespan is 9–10 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 Newfoundland lean, exercised and current on preventive care is the most practical way to reach the upper end of that range. As with all giant breeds, lifespan tends to run shorter than in small dogs, which makes weight management and preventive care count double.

Apartments can work with a solid exercise routine, though more space is preferable. Shedding is moderate; expect some hair on furniture, heaviest during seasonal coat changes. Plan on a middle-of-the-road grooming routine: weekly brushing plus trims now and then. No low-shedding claim applies here. Allergy sufferers should spend time with the breed before committing.

A balanced activity level — think one good walk and a play session most days. Most pick up basics readily but keep sessions short; boredom arrives quickly. Most do fine with respectful children, especially when raised together. Canine housemates generally work out fine, though same-sex pairs can need more management.

Two numbers on this page earn their keep more than the rest: 56.7 kg of average adult weight (heavier than 96% of the 153 breeds catalogued here) and a 9–10 year expected lifespan. Insurance pricing leans on exactly these figures, which is why comparing plans early, before any condition becomes pre-existing, is the standard advice for this breed. Feeding portions, crate sizing and first-year costs below all start from the same AKC-sourced numbers as this page.
