When to Bring Your Outdoor Dog Inside: Temperature Guidelines by Breed & Age

No Single Number — But 40°F (4°C) Is a Safe General Threshold

The decision depends on **breed, coat, age, health, acclimation, and conditions (wind, wet, shelter)**. Use this framework:

General Guidelines by Dog Type

Universal "Time to Come In" Signs

• Shivering, trembling
• Whining, barking at door
• Hunched posture, tucked tail
• Lifting paws alternately
• Seeking shelter (under deck, car)
• Lethargy, confusion (hypothermia — **emergency**)

Outdoor Shelter Minimum Standards (If Must Stay Out)

• **Insulated, elevated floor**, windproof, waterproof roof.
• **Door flap** (clear vinyl), facing away from prevailing wind.
• **Straw bedding** (not blankets — hold moisture).
• **Heated water bowl** (prevent freezing).
• **Size:** Just big enough to stand, turn, lie down (conserves body heat).

Bottom Line

When in doubt, bring them in. A dog's loyalty will keep them outside to please you — until they can't. Your garage, mudroom, or crate is safer than guessing.
