Cairn Terriers in hot and cold weather

Heat: Cairn Terriers handle heat about as well as the average dog. That means care above about 75°F (24°C): shade, water, shorter walks, and a pavement check. Above about 82°F (28°C), stick to potty breaks. Check today's heat risk.

Cold: Cairn Terriers are built for cold weather and usually enjoy it. Paws still need protecting from salt and ice, and very young or old dogs feel the cold more. Check today's cold risk.
