How to Keep Animal Shelters Warm for the Winter

Jon Lantz • February 3, 2025

In New Jersey, we’ve seen a lot of snowstorms and extreme temperatures come our way. It is important to remember that during these cold temperatures, your animals will need to keep warm too. When using a dog house, horse barn, pet enclosure, or run-in shed for your animals, you will need to make sure they are warm enough for them to live in. If your animals can come inside your home, it is best to keep them inside during the night or in the coldest temperatures. If your animals cannot come inside your home, here are some tips on how to keep animal shelters warm for the winter seasons. 


Proper Insulation

Properly insulating your animal shelter will regulate its inside temperature. Adding foam boards around the walls and floor of the structure will add extra insulation, protecting your animals from the frigid outside temperatures. You can even add mylar blankets around the shelter, as they are made with aluminium to reflect heat and keep whoever wears them warm. When building your structure, Jed’s Sheds can customize the insulation method used in your animal shelters to fit your and your pet's needs. We can ensure there is proper insulation inside your shelters to keep your animals warm in the winter. 


Using Straw as Insulation

For animal shelters specifically, straw is a good insulator. Sometimes people use hay for insulation, but it does not absorb moisture like straw does, making straw a better option. Straw helps retain the animal’s body heat, so you can use it to create a warm insulated bed for them to sleep on. Make sure you regularly check the straw they are sleeping on to ensure it is not damp, as damp bedding can cause discomfort. 


Weatherproofing

A well-built, weatherproof structure will greatly improve your animal’s well-being. Jed’s Sheds builds our shelters with weatherproofing in mind, making the structure withstand high winds and heavy snowfalls. For extra weatherproofing, you can plant some shrubs and trees around the shelter to take the bulk hit of the cold winds, making the structure itself less cold. If you have a dog house, you can move it so it is not facing the wind, so there is less of a draft entering the shelter.

Maintain Their Wellbeing

Always Have Access to Veterinary Care

Check on your animals daily to ensure they are eating well, are active, and show no signs of frostbite or hypothermia. It is very important to ensure you have quick access to a veterinarian in case of an emergency. If your animal falls ill or isn’t eating enough, bring them to the vet. Winter is also a good time to do an annual check-up at the vet, they can determine if they are healthy enough to withstand the cold.


Ensure They Have Enough Food and Water

During the winter, animals will need more food intake to retain their energy levels. They use their food intake to regulate their body temperature, so increasing their calorie intake will help their bodies generate more heat. Additionally, frequently check their water bowls as they are likely to freeze in the cold. Always ensure that there is fresh water for them to drink to keep them hydrated. 


Proper Ventilation

There should be ventilation inside the shelter to keep air circulating in and out. If the structure is not ventilated, it can have higher humidity levels which can cause your animals to have respiratory problems. Proper ventilation will reduce moisture buildup, protecting your animals from illnesses. Remember to not have too much ventilation or it will cause a cold draft to enter the shelter, not properly circulating the air. To further ensure no unwanted drafts enter the structure, seal any cracks or holes in the shelter that formed from general wear and tear. Jed’s Sheds has options for ventilation, including ridge vents, that will provide ample airflow for your structure.  

Keeping Horse Barns Warm in the Winter

Since horse barns are a larger structure, they may need more heat than insulation and ventilation can provide. Horses are naturally accustomed to cold temperatures due to their thick winter coats that keep them warm. However, if temperatures reach extreme cold, you may need additional heaters. You can use blankets designed for horses to warm them up or use portable radiant heaters or heat lamps to add additional heat to the barn. Be careful with this though, as the straw and hay that’s in the barn can pose a fire hazard if they are too close to high heat or sparks. You also don’t want to accidentally cause your horses to overheat, which can damage their health.
