Keep Pets Safe in the Heat

Never Leave Pets in a Hot Car

There’s really no scenario where it’s okay to leave your pet inside a parked car on a hot day. People sometimes think they can just crack the windows or run a quick errand and everything will be fine, but that’s not how heat works inside a vehicle. A parked car, even with the windows slightly open, acts like an oven. Within minutes, the temperature inside can skyrocket well beyond what’s safe for any living creature. A mild 75-degree day can see the inside of a car hit over 100 degrees in just ten minutes. When it’s over 90 outside, that temperature climbs even faster, even if you’re just running inside to grab a drink.

Pets don’t regulate heat like we do. They mostly cool themselves through panting, which becomes less effective when the air around them is hot and stagnant. They don’t sweat the way humans do, either—only through their paw pads, and that’s not enough to help them cool down quickly. So when a dog or cat is locked in a hot car, they’re fighting a losing battle. Their internal temperature rises fast, and once it hits 104°F or higher, they’re in the danger zone for heatstroke. Organ damage begins quickly, and without intervention, it can be fatal.

If you ever see a pet left in a hot vehicle, you’re not overreacting by calling authorities. It’s a life-or-death situation. Laws in many places allow good Samaritans to break a window if a pet is clearly in distress and the situation is urgent, but even if you’re unsure of the law in your area, the best first move is always to call 911. Describe the vehicle, give the location, and stay with the animal until help arrives. If you’re a pet owner yourself, the best practice is simple: just leave your pet at home in the summer when you’re out running errands. A short stop could become a tragedy, and it’s just not worth the risk.

Limit Outdoor Exercise in the Heat

Just like humans, pets need exercise to stay healthy. But when it’s hot outside, timing and intensity matter a lot. The middle of the day is usually the hottest and most dangerous time to be outside, especially in direct sunlight. If your dog normally loves a brisk walk or an energetic fetch session, you’ll need to adjust that schedule in summer. Try to get those activities done in the early morning or after the sun starts to set, when temperatures drop and sidewalks aren’t scalding.

The issue with walking or exercising pets in high heat isn’t just exhaustion—it’s that they can’t cool down like we do. Heat builds up in their bodies quickly, especially in short-nosed breeds like bulldogs or pugs, which already struggle with airflow. Overexertion in these conditions can lead to heatstroke, and symptoms like heavy panting, glazed eyes, weakness, or even collapse can come on faster than you’d think. Always carry water with you on walks. If your dog starts panting hard or seems sluggish, take a break in the shade, offer water, and don’t push them further.

Another overlooked risk is hot pavement. Asphalt and concrete hold heat much longer than grass or dirt. If the ground feels hot to your bare hand, it’s too hot for your pet’s paws. Burned pads are painful, slow to heal, and totally avoidable. Stick to grassy trails or wooded areas when it’s warm, and avoid heavily paved areas unless it’s early or late in the day. Booties can help protect your dog’s paws if you absolutely must walk in those conditions, but even then, keep it short and slow.

And some dogs just don’t handle heat well at all. Older dogs, puppies, and dogs with chronic conditions need special care. A five-minute walk might be their maximum during hot weather. Indoor games or short training sessions inside with a fan going can be a safer way to give them some stimulation without putting them at risk. Adjusting your pet’s routine in the summer isn’t spoiling them—it’s just responsible, and it shows you’re paying attention to their needs.

Stick to Grass and Avoid Treated Lawns

When temperatures rise, pet owners often take advantage of longer days and get outside more. That’s good, in theory. But it’s not always as simple as putting on a leash and heading out the door. Warm weather brings hidden risks, especially when you’re walking your dog through suburban or urban areas. Lawn treatments, fertilizers, and pesticides become common in the spring and summer, and many of those products aren’t safe for pets.

Some of these lawn chemicals have sweet smells or flavors that make them appealing to dogs. And pets don’t need to eat a mouthful of grass to get exposed—walking through recently treated lawns can lead to chemical residue on their paws and fur. Later, during grooming, they lick those residues and ingest harmful substances. If you’ve ever noticed little flags sticking out of a grassy area, that’s often a sign the lawn has been chemically treated. Avoid those areas, especially if your dog tends to nibble at grass or sniff everything in their path.

Besides chemical exposure, there’s also the surface temperature issue again. Pavement and concrete walkways can become dangerously hot in the summer. That’s why grass is typically safer. It stays cooler, has more moisture, and is generally easier on a pet’s feet. But even natural grassy areas have their own hazards. Bees, burrs, foxtails, and other natural debris can get lodged in paws, ears, or noses, especially in curious or energetic dogs. Check your pet carefully after walks and consider wiping their paws down when you return home. It takes just a minute, but it reduces the chances of irritation or accidental ingestion of something harmful.

For city dwellers, finding safe walking routes might take a little extra planning. Parks are great, but even public parks sometimes use chemical treatments. You can call ahead or check local notices online. If you have a backyard, consider maintaining it as a pesticide-free zone. It gives you a guaranteed safe space for play and exercise during the hotter months.

Hydration and Shade Are Essential

This part can’t be stressed enough: your pet needs constant access to fresh water during hot weather. Not just a bowl inside that gets filled in the morning and ignored all day, but clean, cool water available wherever they are—inside, outside, on the go. Dogs and cats lose a lot of moisture through panting and minimal sweating, and that means dehydration can sneak up quickly if water isn’t readily available.

If your pet is going to be outside for more than just a quick bathroom break, make sure there’s shade, and not just any shade. A doghouse might seem like a good idea, but it can actually trap heat and make things worse. Open shade, like from a tree or a canopy, is better because it allows for airflow. A plastic kiddie pool filled with water can also be helpful, especially for breeds that like water. Just supervise to make sure they’re using it safely.

Consider freezing water in plastic bottles and placing them near where your pet sleeps outside. They’ll lie next to the cool bottle and draw some relief from it. For indoor pets, fans and air conditioning are ideal, but even a simple cool tile floor can help. Let your pet choose their own resting spot—they’ll naturally gravitate toward the coolest part of the room if they have the freedom.

Portable water bowls or pet water bottles are great when you’re on walks or at the park. Even better if they come with a small dish attachment so your dog doesn’t have to lap water from the sidewalk. Always bring more water than you think you’ll need. A gallon jug in your trunk or backpack can be a lifesaver if plans change or if your dog gets more tired than expected.

And remember, hydration isn’t just about preventing thirst. It also helps regulate body temperature and supports vital organ function. A well-hydrated pet is far less likely to overheat. Keep an eye on signs of dehydration: dry gums, sunken eyes, lethargy, and dark urine. If your pet seems unusually tired or is refusing to drink, it might be time to cut the outing short and get them into a cooler place.

Provide Access to Air-Conditioned Areas

When temperatures soar, especially in regions where summer heat can last for weeks or months, pets need real indoor refuge. While shade and water help, there’s no substitute for an air-conditioned environment. Pets, like humans, have limits to how much heat they can handle before their health starts to deteriorate. And it’s not just the temperature—it’s also the humidity. When the air is thick with moisture, it becomes even harder for animals to cool themselves through panting. That’s why an indoor space with air conditioning is the most reliable way to keep them safe and healthy.

This is especially critical for pets that already have trouble with heat. Brachycephalic breeds like pugs, French bulldogs, Persian cats, and boxers are particularly vulnerable. Their flat faces mean shorter airways, which restrict how efficiently they can pant. Add heat into that equation, and it becomes dangerous fast. Older pets and those with heart, lung, or kidney disease are also high-risk in hot weather. A temperature that seems warm but tolerable to you could be enough to push a vulnerable animal into distress.

Air-conditioned areas don’t need to be fancy. A single room with a fan, some tile flooring, and closed blinds can do the job if it’s cool enough. If you don’t have AC at home, make sure windows are open for ventilation and position fans strategically to keep air moving. Even a basement room might be significantly cooler than the rest of the house. The goal is to provide your pet with at least one safe spot to rest where they’re protected from direct sunlight and extreme heat.

And if you’re traveling, make pet-friendly accommodations a priority. Car rides in the heat can be brutal without proper planning. Use sunshades for windows, keep AC flowing consistently, and take frequent breaks to offer water. Never keep your pet in a hot tent or car during road trips or vacations. If you’re heading somewhere rural or camping, battery-powered fans and cooling mats can offer some relief, but they’re not a full replacement for temperature-controlled environments.

If your pet does overheat, you’ll need to act fast. Signs of heatstroke in animals include heavy panting, drooling, vomiting, diarrhea, lethargy, and uncoordinated movements. If your pet’s gums appear bright red or pale, or if they collapse, that’s an emergency. Move them to a cooler space immediately, apply cool (not cold) water to their body, and get veterinary help right away. AC access isn’t just about comfort—it could be the one thing that saves your pet’s life during extreme heat.

When in Doubt, Keep Pets Indoors

Sometimes people try to split the difference—leaving pets outside under a tree with a bowl of water, thinking that’s enough. But in many cases, it’s not. The reality is that pets should just stay indoors during hot days unless they have a specific reason to go out, like using the bathroom or going on a short walk. The risks of heat-related illness are too high, especially for animals that don’t have enough ways to cool down on their own.

Indoors doesn’t have to mean isolated. Set up your pet’s space where they still get social interaction and a view of the outdoors if possible. Close the blinds during the hottest part of the day to keep the sun from heating the room. Open windows early in the morning or late at night when the air is cooler. Use fans to improve airflow. Even if you don’t have air conditioning, these steps help lower the indoor temperature by several degrees.

Avoid glass-enclosed areas like sunrooms or conservatories unless you’re actively cooling them. These spaces can heat up like ovens even on days that seem relatively mild. Balconies are another risk, especially for city pets. Concrete floors hold heat, there’s little airflow, and pets can get sunburned or overheat quickly with no way to retreat.

Cooling mats, damp towels, or frozen water bottles wrapped in cloth can offer extra relief inside. If your home isn’t staying cool enough, consider visiting pet-friendly public places like libraries or pet stores during the hottest hours of the day. Some communities open cooling centers for pets and people alike during heat waves. Use them if needed.

At night, when the temperature dips a bit, you can consider letting pets outside for short periods. But even then, supervise carefully and don’t let them stay out too long. Heat stored in asphalt and concrete can linger after sunset, and nocturnal predators or toxic insects can pose new threats.

Most of all, stay aware. Heat-related illnesses sneak up slowly. Just because a dog or cat isn’t actively panting doesn’t mean they’re okay. Sometimes, they’ll just retreat to a quiet corner and lie down, seemingly normal, until symptoms suddenly get worse. If you’re unsure, bring them inside and observe. Better safe than sorry.

Additional Tips for Summer Pet Safety

There are a few more practical habits that can make summer easier and safer for pets. Start with grooming. A well-groomed coat helps regulate body temperature. That doesn’t mean shaving, though—especially not for double-coated breeds like huskies or golden retrievers. Their fur helps block the sun and insulate against heat. Shaving it can make them more vulnerable. Instead, regular brushing helps remove excess fur and reduce the risk of overheating.

Paw care is another overlooked detail. Dogs walking on rough, hot surfaces can wear down their pads or pick up painful debris like thorns or burrs. Check their feet after each walk, especially in summer. Keep nails trimmed so their gait stays normal. Overgrown nails can alter posture and increase the risk of injuries, especially on slick or hot surfaces.

Parasite prevention is also vital in the warm months. Fleas, ticks, and mosquitoes all thrive in heat. And mosquitoes carry heartworms, which can be deadly for dogs and cats if left untreated. Monthly preventatives are widely available and often cover several parasites at once. Talk to your vet about what’s best for your region and your pet’s specific risk factors. Never skip a dose in the summer.

If you have a pet who spends time in a backyard or enclosed patio, inspect the space regularly. Look for ant mounds, bees’ nests, or puddles that could be breeding grounds for insects. Remove any plants that are toxic to animals. Oleander, sago palm, and lilies are just a few examples of common warm-weather plants that can cause serious harm.

And finally, don’t assume animals can self-regulate like people can. They often don’t realize how hot they’re getting until it’s too late. A dog may keep chasing a ball out of excitement even if it’s already overheating. That’s where your judgment matters. Offer breaks, limit playtime, and always observe how your pet is responding.

Conclusion

Keeping pets safe in the heat is really about paying attention to their limitations, understanding how their bodies handle warmth, and adjusting your habits accordingly. Most pets want to be near you and part of the action, but they don’t always know how to protect themselves. That’s your job. Give them cool spaces, plenty of water, shade, and indoor refuge. Don’t leave them in cars, avoid peak sun hours, and make thoughtful decisions about walks, play, and travel.

Summer doesn’t have to be a dangerous time. With some awareness and planning, it can still be full of adventures and shared moments with your animals—just safer ones. You don’t need expensive gear or complicated routines. Just think about what your pet’s experiencing and make changes that protect them from the dangers of heat. The more you build that into your daily rhythm, the more it becomes second nature. And that’s good for everyone involved.
