Excellent explanation from A Solo Traveler ❤🐾☃️
Blankets vs straw in cold weather:
Towels are Wicks. Why Blankets Freeze Dogs. ❄️🐕
We treat them like humans. "It's cold, I'll give him a blanket." In a heated house, that's fine. In an unheated dog house, that blanket is a death trap. The physics of Capillary Action turns comfort into a freezing hazard.
🧽 1. The Sponge Effect Fabric is hygroscopic (water-loving). Even if the floor is only slightly damp, a towel or blanket acts as a Wick. It pulls moisture up from the floor and absorbs the humidity from the dog's breath. Within hours, the fabric is damp. When the temperature drops, that damp fabric freezes solid.
🥶 2. The Thermal Heatsink A dry blanket insulates because it traps air. A wet blanket insulates nothing. Water conducts heat 25 times faster than air. A wet towel sucks the body heat out of the dog and transfers it to the ground. The dog is essentially sleeping on a sheet of ice that is actively cooling them down.
🌾 3. Straw: The Hollow Insulator The solution is Straw (or Cedar Shavings). Straw is hollow. It traps dead air inside its stems (insulation). Crucially, it is Hydrophobic. It doesn't wick water. Moisture sinks to the bottom, away from the dog, while the top layer stays dry and warm. The dog can burrow into it, creating a "nest" that retains heat.
The Rule: If there is no heater: No Fabric. Fill the shelter with Straw (not Hay!) so the dog can burrow.
📌 QUICK FAQ
Q: Why not Hay? R: Hay is food. 🐴 Hay (green grass) absorbs moisture, rots, grows mold, and freezes into a brick. Straw (yellow stalks) is bedding. It repels moisture and stays fluffy. Straw = Sleep. Hay = Eat.
Q: Are Cedar Shavings safe? R: Yes, with a caveat. 🌲 Cedar is excellent because it repels fleas and smells good. However, for extreme cold, long-stem Straw is better because it allows the dog to "nest" (burrow and cover their nose/paws). Shavings tend to pack down flat.
Q: What if I change the blankets every day? R: Risky. ⚠️ Unless you change them every few hours, a wet snowstorm or high humidity can freeze the blanket in the middle of the night. Straw is a passive safety system that works for weeks without intervention.
▶️ The donor funded NMDOG Statewide FREE STRAW Program provides straw to Shelter, Animal Control & Law Enforcements partners across the state of NM, every winter for the past 14 years. They, in turn, distribute the straw for FREE to those in their communities who keep their dogs outside. Link to this resource album can be found in the comments.
At NMDOG, we believe all dogs should live inside as part of the family - but we understand that is not the reality for many. Our goal with this Outreach program is to make the freezing temps more bearable for as many as we can ❤🐾☃️
