When summer arrives, many pet owners wonder: how hot is too hot for dogs? In general, once temperatures rise above 85°F, dogs can begin to struggle with heat. Unlike humans, dogs cannot cool themselves efficiently, and high temperatures combined with humidity or direct sun can put them at risk of heat-related health concerns. The team at Mills Animal Hospital can help you recognize when it is too hot outside for your dog to help you protect them and plan safe activities year-round.
Why Temperature Affects Dogs Differently Than Humans
Dogs do not sweat the way people do. Their primary way of cooling off is through panting, which becomes less effective when temperatures rise. This is why the question “How hot is too hot for dogs?” matters so much. What feels warm to you may feel dangerously hot to your pet. Several factors influence how a dog tolerates heat:
- Breed type: Flat-faced breeds such as Bulldogs, Pugs, and Shih Tzus have a harder time cooling off.
- Coat thickness: Dogs with heavy coats, like Huskies or Newfoundlands, retain more heat.
- Size and weight: Overweight pets are at greater risk when the temperature climbs.
- Age and health: Puppies, senior dogs, and those with health conditions can be more sensitive to high temperatures.
How Hot is Too Hot for Dogs on Different Surfaces
Air temperature isn’t the only factor. Surfaces like asphalt and concrete absorb heat quickly, creating conditions that can harm your dog even if the air feels bearable. When asking how hot is too hot for dogs, consider the ground temperature:
- Asphalt: On a sunny 85°F day, asphalt can reach 135°F or hotter. That’s hot enough to burn paw pads.
- Concrete and sand: These can also heat up rapidly, making walks uncomfortable or unsafe.
- Grass and dirt: These surfaces tend to stay cooler, providing safer walking conditions.
The “Paw Test”
A good rule of thumb is to place your hand on the ground for seven seconds. If it feels too hot for you, it’s too hot for your dog’s paws. This simple test helps you decide if outdoor exercise is safe or if it’s time to wait until temperatures cool.
How Hot is Too Hot for Dogs in Cars
One of the most dangerous situations for dogs occurs in parked vehicles. Even with windows cracked, temperatures inside a car rise quickly. If the outside temperature is 85°F, the inside of a car can reach 100°F in just 10 minutes and soar to 120°F within half an hour. For this reason, veterinarians and animal welfare groups consistently stress that the answer to “How hot is too hot for dogs in cars?” is simple: any temperature. Dogs should never be left unattended in a vehicle, no matter the season.
Signs That the Heat is Too Much for Your Dog
Knowing how hot is too hot for dogs also means recognizing signs that your pet may be struggling. These include:
- Heavy or rapid panting
- Excessive drooling
- Weakness or lethargy
- Vomiting
- Glazed eyes or lack of coordination
When to Act Quickly
If your dog shows any of these signs, it’s important to get them into a cooler environment right away. Move them into the shade or an air-conditioned space and provide fresh water.

How Humidity Impacts Your Dog’s Body Temperature
Heat is only part of the equation. Humidity makes it harder for dogs to regulate body temperature. Panting works by allowing moisture to evaporate from the tongue and respiratory tract. In humid conditions, evaporation slows down, making panting far less effective. This means that on a humid 80°F day, your dog may feel hotter than on a dry 90°F day. Understanding how hot is too hot for dogs requires considering both the thermometer and the humidity level.
How Hot is Too Hot for Dogs During Exercise
Exercise generates heat, so dogs are more vulnerable when running, playing fetch, or walking long distances in warm weather. Even active breeds with high stamina can overheat if conditions are extreme. Pet owners should plan exercise early in the morning or later in the evening when temperatures are cooler. Shorter walks on shaded routes or grassy surfaces are safer choices.
Hydration and Breaks
Always carry water and take frequent breaks in shaded areas. Allow your dog to rest often during activity. These small steps help reduce the risks associated with exercising when it’s hot outside.
Is it Too Hot for Your Dog at Home?
Even at home, pet owners should think about how hot is too hot for dogs. A backyard with limited shade or a deck exposed to full sun can heat up quickly. Provide shaded spots, plenty of water, and avoid leaving pets outside for extended periods during the hottest hours of the day. For dogs who live indoors, air conditioning, fans, and cooling mats can help keep them comfortable.
How Hot is Too Hot for Dogs Based on Breed and Lifestyle
Different dogs have different tolerances for heat. Understanding this helps you tailor care to your individual pet:
- Short-nosed breeds: Bulldogs, Boxers, and Boston Terriers are prone to heat sensitivity.
- Long-haired breeds: Collies, German Shepherds, and Retrievers may need shorter outdoor playtimes.
- Working and sporting breeds: While active, they can still overheat if pushed too hard in hot weather.
- Small dogs: Chihuahuas and other toy breeds can struggle because of their smaller body mass.
When considering how hot is too hot for dogs, always think about your pet’s unique breed, size, and health status.
