Newfoundland Weather Tips

Heat caution starts at 72°F

Limit outdoor time to 15 minutes. Stick to grass, bring water, and avoid pavement.

Cold caution starts at 10°F

Limit outdoor time to 60 minutes. Use a coat and watch for shivering.

“Newfoundlands are the MOST heat-sensitive large breed. Their massive double coat + 100-150 lb body generates and traps tremendous heat. Their 72°F caution threshold is the lowest of any non-brachycephalic breed.”
“They were bred for the icy waters off Newfoundland, Canada — literally designed for cold. In summer, they're a fish out of water. Air conditioning is not optional for Newfie owners.”

Do Newfoundlands need a coat in winter?▾
Newfoundlands have one of the most impressive double coats in the dog world — a long, coarse outer coat with a dense, soft undercoat. It provides extraordinary cold insulation, comfortable down to about 10°F. Their coat is naturally oily and water-resistant. They were bred for icy North Atlantic waters.
