So you want to keep your dog — or cat, no judgement here — in the garage while you’re away from home? No problem! I mean, who doesn’t need a break from our old furry friends from time to time… The truth is, the garage may be the safest place for a pet suffering for separation anxiety while you are away at work, IF you follow these important guidelines.
Don’t worry, this blog isn’t about building cages. Since we all want our animals to roam free, we’ll discuss how to use the entire garage space and transform it into the perfect place for that special four‑legged family member.
The short answer is: It’s generally not recommended to keep dogs in an unheated garage during winter.
While a garage might seem like a reasonable shelter from harsh winter elements, it presents several significant risks to your dog’s health and wellbeing. According to the article from Best Pet Facts, garages often have:
- Temperature fluctuations – Garages typically lack proper insulation, making them vulnerable to dangerous cold temperatures, especially at night
- Toxic hazards – Antifreeze, motor oil, pesticides and other chemicals commonly stored in garages can be lethal if ingested
- Poor ventilation – This can lead to carbon monoxide buildup, particularly if vehicles are started in the space
- Isolation issues – Dogs are social animals and being separated from their family can cause psychological distress
When Is It Too Cold?
Generally. temperatures below 45°F (7°C) are considered too cold for most dogs. especially
- Small breeds
- Short-coated dogs
- Senior dogs
- Puppies
- Dogs with health conditions
Even dogs with thick coats can suffer from hypothermia or frostbite if exposed to cold temperatures for extended periods. The article notes that their thick coat “doesn’t make your dog immune to the dangers of a cold garage.”
Signs Your Dog Is Too Cold
Watch for these warning signs of hypothermia:
- Persistent shivering
- Lethargy or decreased energy
- Weakness or unsteadiness
- Pale or bluish gums
- Muscle stiffness
- Confusion or disorientation
If you notice any of these symptoms, bring your dog inside immediately, wrap them in a warm blanket, and contact your veterinarian.
Making a Garage Safer (If It’s Your Only Option)
If you absolutely must use a garage temporarily, here are the minimum requirements:
- Proper insulation to maintain a stable temperature
- Safe heating source – avoid propane heaters due to carbon monoxide risks
- Secure all chemicals in sealed, pet-proof containers
- Install a carbon monoxide detector
- Regular monitoring to ensure your dog remains comfortable
- Emergency backup plan in case of power outages
Better Alternatives to the Garage
The article strongly recommends these safer options
- Bring your dog inside – The best solution is allowing them to live in your home
- Create a designated indoor space – If needed, set up a specific area like a laundry room
- Invest in a heated, insulated dog house – If outdoor time is necessary
- Consider doggy daycare or boarding – For times when you’ll be away
Final Thoughts
The article emphasizes that while some garages might offer minimal protection from direct exposure to snow or rain, they’re rarely suitable winter accommodations for dogs. Temperature control, toxic hazards, ventilation issues, and social isolation all pose significant risks.
For your dog’s health, safety and wellbeing, indoor options should always be prioritized during winter months If you’re unsure about the best arrangement for your specific dog, consult with your veterinarian for personalized advice.
Remember: your dog’s comfort and safety should always be your guiding principle when making housing decisions during cold weather.

The feeding of garage favored
Do not change your pet’s eating habits — leaving a bowl of food in the garage is no different than in your home. Follow the manufacturers’ recommendations found on the label and you’ll be fine. Keep in mind that your dogs may sleep more during your absence, saving all their energy so they can shower you with affection when you return!
Please write this one somewhere: never leave a pet without water. Make sure the bowl cannot be accidentally knocked over.
On garage temperature and isolation
No pet should be kept in an uninsulated space. A well‑insulated and weathertight garage is the best option for your pet, whether it’s in the cold weather of winter — keep the interior temperature at or over 50℉ (10℃) — or the summer’s burning heat.
Speaking of burning heat: a window will provide some natural air ventilation if you leave it partially opened.
The accumulation of humidity in the garage, especially in the winter, is another factor to consider. If you think you have a humidity problem, simply measure the level with a hygrometer. Your pet will be comfortable below 50%, so envisage using a dehumidifier if the value is higher.
