Safe Temperatures for Dogs Outside: What Every Owner Should Know

Every year, thousands of dogs suffer from preventable emergencies — like heatstroke or hypothermia — often because their owners simply didn’t realize the danger.

It’s not just a rare tragedy. It's happening every day:

• In just the 2024–2025 winter season, at least 49 dogs and other pets have been reported dead from cold exposure - and another 594 had to be rescued.
  

• In summer 2023 alone, over 123 dogs and cats died from extreme heat - double the number from the year before.
  

• And experts agree: most cases go unreported, meaning the real numbers are even higher.

If you love your dog like family, it’s critical to know the safe temperatures for them to be outside - and how to protect them before it’s too late.

This guide will help you understand how different weather conditions impact dogs, what’s safe (and what’s not), and what steps you can take to keep your best friend safe year-round.

Quick Guide to Dog Temperature Safety

• Small and short-haired dogs are at higher risk in both cold and heat.
  

• Hot weather dangers are just as serious as cold weather risks.
  

• Puppies, seniors, and sick dogs need stricter precautions.
  

• Always watch for emergency signs like shivering, panting, or weakness.
  

• Stay updated on local outdoor dog laws and regulations.

Why Temperature Impacts Dogs Differently

Dogs regulate body heat differently than humans. They can’t sweat like we do - they mainly cool down by panting.

Factors that affect a dog’s safety outside include:

• Breed and Size: Thick-coated breeds handle cold better; small or short-haired dogs chill faster.
  

• Coat Type: Double coats insulate against cold; short coats offer little protection.
  

• Age and Health: Puppies, seniors, and sick dogs can't regulate their body temperatures as easily.
  

In short, dog safety depends not just on temperature but on who your dog is.

🥶 Cold Weather Safety for Dogs

Safe Cold Temperatures for Dogs Outside

Here’s a general guide based on breed size and coat thickness:

Always check the wind chill. It can make 30°F (-1°C) feel like 10°F (-12°C)!

---

Cold Weather Safety Checklist

• Shorten walks below 32°F (0°C).
  

• Use dog coats and boots for protection.
  

• Dry your dog’s paws and belly after walking in snow.
  

• Watch for ice between paw pads.
  

• Shelter outdoor dogs properly - waterproof, insulated, raised off the ground.

Special Cold Risks

Puppies, Toy Breeds (like Chihuahuas and Yorkies), seniors, and thin-coated dogs (like Greyhounds) are especially vulnerable.

If your dog falls into one of these groups, outdoor time should be very limited in cold months.

☀️ Hot Weather Safety for Dogs

Safe Hot Temperatures for Dogs Outside

Unlike cold, heat sneaks up quickly on dogs. Here’s the basic breakdown:

Remember: Dogs feel much hotter than we do because of their fur and limited cooling systems.

---

Hot Weather Safety Checklist

• Provide constant access to fresh, cool water.
  

• Walk during early mornings or evenings.
  

• Avoid hot pavement - if it’s too hot for your hand, it’s too hot for paws!
  

• Set up shaded shelters or cooling mats outdoors.
  

• Never leave a dog in a parked car - not even for a minute!
  

---

Special Hot Risks

Flat-faced breeds (like Bulldogs, Boxers, and Pugs) overheat much faster.

Senior dogs, puppies, and dogs with heart or respiratory conditions are also at high risk.

🐶 Dog Breeds Most at Risk

Cold Weather Risks

Some dog breeds are much more vulnerable to cold temperatures because of their small size, thin coats, or low body fat. They can lose heat quickly - putting them at greater risk for hypothermia and frostbite.

Here are breeds most at risk:

• Chihuahua - Tiny size and thin coat cause fast heat loss.
  

• Greyhound - Low body fat and thin skin offer little cold protection.
  

• French Bulldog - Short coat and flat face make them cold-sensitive.
  

• Whippet - Slim build and fine coat provide minimal insulation.
  

• Miniature Pinscher - Small size and sleek coat make them vulnerable.
  

Important:
Even energetic dogs can suffer from cold quickly. Watch for signs like shivering, whining, or stiffness.

Tip:
Dress cold-sensitive breeds in jackets or sweaters during winter walks, and limit outdoor time when temperatures drop.

Hot Weather Risks

Some breeds are much more prone to heatstroke than others - and it can be deadly.

In fact, 26.56% of dogs who suffered heatstroke did not survive, according to recent studies.
Flat-faced breeds, also called brachycephalic breeds, are at especially high risk. Nearly half (48.7%) of all dogs with heatstroke were flat-faced breeds. These breeds are four times more likely to develop heatstroke than normal-faced dogs.

Here are some of the dog breeds at the highest risk:

• English Bulldogs and French Bulldogs - Their short snouts make it very hard for them to cool themselves by panting.
  

• Pugs - Another flat-faced breed that struggles with hot weather.
  

• Chow Chows - Their thick double coat traps heat inside.
  

• Newfoundlands - Large size and heavy fur make them vulnerable to overheating.
  

• Pomeranians - Their small size and dense coat make it harder to cool down.
  

• Staffordshire Bull Terriers - They are also at a higher risk compared to many other breeds.
  

• Shih Tzus - Their flat face combined with a long coat makes them very heat-sensitive.
  

Other factors that increase a dog’s risk of heatstroke:

• Age - Dogs between 4-6 years and 8-10 years are more likely to suffer heat-related illnesses than dogs under 2 years old.
  

• Sex - Male dogs have a higher risk of developing heat-related illnesses compared to females.
  

Tip: If your dog is one of these breeds - or has a thick coat, short nose, or health issues - be extra cautious during warm weather and follow all the hot weather safety guidelines.

How to Keep Your Dog Safe When They’re Outside

Tracking and Safety Tools for Outdoors

While traditional ID tags are helpful, tech tools like AirTags or GPS collars add another layer of protection if your dog gets loose during bad weather.

• AirTags (like our Leather AirTag Dog Collar) are lightweight, stylish, and perfect for tracking your dog in neighborhoods or parks.
  

• GPS Trackers are better for rural or off-grid areas but require charging and monthly subscriptions.
  

Having one of these tools ensures you can find your dog quickly if they wander - especially important during storms, heatwaves, or blizzards. See our head to head comparison on AirTag collars vs GPS collars for a detailed breakdown of pros and cons of each.

Outdoor Dog Laws You Shouldn’t Ignore

In recent years, many states have passed laws to protect outdoor dogs:

• Below 32°F (0°C) or Above 90°F (32°C): Many places prohibit keeping dogs outside for long periods.
  

• Tethering: Some states limit tethering time to 30 minutes max.
  

• Shelter Requirements: Adequate shade, water, and protection from rain, wind, and snow are often legally required.
  

Violating these laws can lead to heavy fines - or worse, losing your dog. You can read more on what animal control can do to your dog in our detailed guide.

Always check your specific city or state regulations before leaving your dog outside for any length of time.

Safe Temperature for Dogs Outside FAQs

Can I leave my dog outside in 40 degrees (4°C)?

It depends. Healthy, medium-to-large dogs with thick coats can tolerate 40°F (4°C) for a while. Small, short-haired dogs should have very limited time outdoors.

Can I report my neighbor for leaving their dog outside?

Yes, especially if temperatures are extreme and there’s no shelter or water. Call animal control or your local non-emergency police line.

Can dogs survive cold nights?

Not always. Below freezing, dogs can suffer frostbite or hypothermia quickly without shelter. Indoor sleeping is always safest.

At what temperature do dogs need jackets?

Under 45°F (7°C), short-haired, small, senior, or sick dogs usually benefit from jackets for walks or outdoor time.

How long can dogs be outside in the cold?

Limit walks to 15–30 minutes below 32°F (0°C). Below 20°F (-6°C), only short potty breaks are recommended.

How cold is too cold for dogs' paws?

Anything below freezing (32°F or 0°C) can be risky, especially on icy or snowy surfaces.

Paws can suffer frostbite when temperatures fall below 32°F (0°C), especially if exposed to snow, ice, or cold water.

How can I keep an outside dog warm in winter?

Provide a heated, insulated doghouse, waterproof bedding, fresh unfrozen water, and weatherproof coats or boots.

Can dogs get heatstroke in 80°F (27°C) weather?

Yes, especially brachycephalic breeds, seniors, and puppies. Always provide shade and water, and avoid midday walks.

What are signs of heatstroke in dogs?

Heavy panting, drooling, vomiting, red gums, and collapsing are signs. Move your dog to a cool area and contact your vet immediately.
