“Can I leave my dog in the car in winter?” It’s a question that arises all too often during the colder months. However, the answer comes with critical considerations for your furry friend’s safety. 

While it may seem convenient, leaving your dog in a cold car poses serious risks. In harsh weather conditions, vehicles can quickly become hazardous environments for dogs. If they’re exposed to plummeting temperatures, this will most likely lead to a range of health issues and potential emergencies. 

There are several more compelling reasons why leaving your dog in the car in winter is inadvisable and potentially harmful to their well-being. This guide lists them all and provides better alternatives, so stick to the end. 

How Do Dogs Regulate Their Temperature?

Dogs regulate their temperature through several mechanisms. Primarily, they rely on their fur coat, their natural physical insulator that helps trap heat close to their bodies. Dogs also have thermoreceptors in their skin, instantly detecting changes in temperature and sending signals to the brain, particularly to the hypothalamus, which serves as the body’s thermostat. 

These signals prompt the brain to initiate responses such as vasoconstriction—this happens by reducing blood flow to the skin to minimize heat loss and causing shivering to push the body to generate additional warmth through muscle activity. 

Another way for dogs to regulate their body temperature is by seeking sheltered areas or curling up to conserve body heat.

Factors That Affect Cold Tolerance in Dogs

Various factors play a role in determining how well a dog can withstand cold temperatures and adapt to changing weather conditions. Understanding how these can influence cold tolerance in dogs will enable you to make informed decisions as you ensure your pet’s comfort and safety during the cold months. 

Age

Puppies are highly vulnerable to the cold mainly due to their underdeveloped immune systems. Thus, they need extra care and protection, such as insulated clothing and allowing them to come in contact with their littermates for a warm huddle and access the mother’s udder. 

If puppies are nursed by their mothers, not only do they receive essential warmth but also nourishment from the colostrum produced, which further aids in their thermoregulation.

Old dogs are no exception regarding sensitivity to temperatures. Due to their age, they may already have diminished metabolic rates and reduced muscle mass, which impair their ability to thermoregulate. Other reasons include age-related physical changes, like thinning hair. 

Health Condition

If your dog has underlying conditions, they may have compromised immune systems or reduced body circulation, making them susceptible to the cold. 

Hypothyroidism is an example of a health issue whose symptom is sensitivity to cold. To manage this symptom, among others, it’s necessary that it be treated promptly with the help of a licensed veterinarian. 

Dogs diagnosed with diabetes are also at risk during cold exposure primarily due to a faulty redistribution of blood flow. This potentially leads to reduced blood flow to extremities like the paws and ears, increasing the risk of frostbite and other cold-related injuries.

Breed

Your dog’s breed also significantly influences their ability to tolerate cold temperatures. Certain dog breeds, particularly Siberian Huskies, Saint Bernards, Samoyeds, and Alaskan Malamutes are bred for cold climates. They have thick, double coats, which are great insulators against the cold. 

On the other hand, dogs with short coats or minimal body fat, like Chihuahuas, Chinese Crested Dogs, and American Hairless Terriers, may need extra protection from the cold. You can help them stay warm by making them wear sweaters or jackets, especially when outdoors. 

Body Size

Generally, the larger the animal is in terms of body mass and muscle, the more they can generate and retain heat than smaller species. This suggests that larger dog breeds can withstand the cold better than smaller pooches, like Chihuahuas, Pugs, etc. 

However, while body size is a factor, other aspects such as coat type, age, pet’s health condition, and acclimatization also play important roles in a dog’s ability to cope with cold weather. 

Acclimatization

Acclimatization also factors into a dog’s tolerance level to cold. If dogs are exposed to colder climates over time, they generally undergo physiological changes to adapt to the environment, particularly temperature. 

An example of a dog coping with a cold climate is the development of a thicker coat, which provides better insulation and the ability to trap body heat close to the skin. Such a change occurs gradually until the dog ultimately improves its ability to withstand colder temperatures. 

However, if you’re contemplating acclimating your dog from a warm to a cold climate, you must do so cautiously and gradually. Abrupt exposure can be overwhelming and may lead to discomfort or health issues. Also, even after acclimatization, your dog may still require extra care. This may include providing them winter clothing and access to warm and sheltered areas. 

Reasons Why Leaving a Dog in the Car in the Winter Is Risky

Although the more commonly heard cases are dogs being left in hot cars, dogs in cold vehicles also face certain dangers. Vehicles don’t provide enough insulation from cold temperatures and may even rapidly transform into hazardous environments for dogs. This is especially so if they’re still a puppy or a senior dog with various health conditions. 

Below are the primary reasons why you should never leave your dog unattended in the vehicle during the cold season:

Hypothermia

Dogs left in cold vehicles will likely develop hypothermia. This is a serious and often fatal condition where their body temperature drops to a dangerously low level. Symptoms, such as lethargy and shivering, may show. If left untreated, this could lead to organ failure and even death. 

Frostbite

If a dog has been trapped inside an extremely cold car for prolonged periods, there’s a good chance it’s exposed skin, especially the ears and tail, will result in tissue damage and eventually develop into a frostbite case.

Cold-induced Joint Pain

It’s been studied that humans with osteoarthritis are more likely to experience it worse when exposed to low temperatures. The same can be true for most dogs with joint or musculoskeletal issues.

Respiratory Issues

Cold air can irritate your dog’s respiratory system. When this happens, this may lead to coughing, wheezing, and other breathing difficulties. 

Decreased Immunity

A dog subjected to an abrupt drop in temperature and exposed to it for long periods is highly likely to have a weakened immune system. Once their immunity is compromised, they become susceptible to infections and illnesses. 

Elevated Stress Levels

Leaving a dog unattended in a cold car can cause significant stress and anxiety. If this happens often, the constant distress the dog experiences may develop into long-term behavioral issues.

Alternatives to Leaving a Dog in the Car in the Winter

The common question, “Can I leave my dog in the car in winter?” is answered with a resounding no, given all the major reasons why it’s a bad idea or practice. Mostly, this is just as dangerous as leaving them in a hot car. 

Since cars can act like refrigerators, they can hold in the cold and cause temperatures inside to drop to dangerous levels. 

Due to the risks it poses, below are some safer alternatives you may consider when running errands or going places with your dog in the vehicle: 

  • Dog daycare: If you have a matter to attend to during the road trip and can’t bring your dog with you, consider utilizing dog daycare facilities where your pet can be taken care of as you do your business. This protects them from the dangers of being in a cold car and provides them with socialization opportunities. 
  • Pet-friendly stores: Instead of leaving a dog in the car in winter, consider looking for pet-friendly stores and establishments that allow pet owners to bring their four-legged companions. 
  • Leave pets at home: Leave your pets at home if someone can look after them. This is practically the safest option since your home can provide your dog a warm and comfortable environment. 
  • Use a pet sitter: If you’re off for a long ride during the winter, consider hiring a pet sitter instead of bringing your dog with you. You can also ask one of your family members or friends to watch your dog while you’re away.
  • Portable crates: Many dog owners opt to leave their dogs in the car because they find it inconvenient to bring them along. If this is the case, invest in a portable dog car crate or carrier. This is so you can take your dog anywhere as you go about your activities.
  • Carry supplies: If you must take your dog in the car, provide them with extra blankets for insulation and a warm space inside the vehicle. However, it’s still not recommended that you leave them unattended. 
  • Climate control features: Turn on your vehicle’s safe features, like the climate control system, that can run safely without the engine. This can maintain a stable and comfortable temperature for your dog inside the parked car. Still, you must keep your dog safe by monitoring them regularly. Also, it remains advisable not to leave your dog alone in the car regardless of how quick your errands are.
