How to keep your dog cool and safe this summer (vet-backed tips)

Summer is one of the best seasons to spend time with your dog, but it's also one of the most dangerous if you're not paying attention to the heat. Dogs don't regulate body temperature the way we do. They rely almost entirely on panting, and when the air temperature is already 90°F, panting just doesn't cut it.

With large parts of the US currently dealing with serious heat waves, now is the time to update your warm-weather routine. Here's everything you need to know to keep your dog comfortable, safe, and mentally stimulated even when it's too hot to do much outside.

Why dogs overheat faster than you think

Dogs have a normal body temperature between 101°F and 102.5°F. Heat stroke begins at 104°F and becomes life-threatening at 106°F. The gap between "fine" and "in danger" is smaller than most pet parents realize, and it can close in minutes.

A few reasons dogs are especially vulnerable in summer:

Panting is their only real cooling mechanism. Dogs have sweat glands only in their paw pads, which barely moves the needle on body temperature
Humidity makes it worse. When the air is humid, panting becomes less effective because moisture doesn't evaporate off their tongue as quickly
Pavement holds heat. Asphalt can reach 150°F on a 90°F day. If you can't hold your hand on the pavement for 5 seconds comfortably, it's burning your dog's paws
Some dogs are higher risk. Brachycephalic breeds (Bulldogs, Pugs, French Bulldogs), older dogs, overweight dogs, and dogs with dark coats overheat faster than others

Warning signs of heat exhaustion and heat stroke

Knowing the difference between a tired dog and a dog in danger can save their life.

Watch for:

Early warning signs (act quickly):

Heavy, excessive panting that doesn't slow down
Drooling more than usual
Seeking shade or refusing to walk
Slowing down significantly on walks
Bright red gums

Emergency signs (get to a vet immediately):

Vomiting or diarrhea
Stumbling or loss of coordination
Glassy eyes or disorientation
Collapse or loss of consciousness
Gums that turn pale, gray, or blue

If you see emergency signs, move your dog to a cool area immediately, apply cool (not ice cold) water to their neck, armpits, and groin, and get to a veterinarian as fast as possible. Do not wait to see if they improve on their own.

Outdoor safety: smart adjustments for hot days

You don't have to cancel outdoor time entirely, but you do need to rethink the timing and structure of it.

Shift walks to early morning or evening

The safest outdoor window is before 9 AM or after 7 PM when pavement has had time to cool. Midday walks from 11 AM to 4 PM are the highest risk period in most of the US during summer.

Keep walks shorter than usual

Even in cooler morning hours, summer air is warmer and more humid than your dog is used to. Cut your usual walk time by 25-30% and watch your dog's panting closely throughout.

Always bring water

Carry a collapsible bowl and fresh water on any walk longer than 10 minutes. Dogs should drink small amounts frequently rather than a large amount all at once after exercise.

Check the pavement before you walk

Place the back of your hand flat on the pavement for 5 seconds. If it's uncomfortable, it will burn your dog's paw pads. Stick to grass, dirt paths, or shaded sidewalks when possible.

Never leave your dog in a parked car

Even with windows cracked, a car can reach 120°F in minutes on a hot day. This applies even for "just a few minutes" errands. It's not worth the risk.

Indoor enrichment: how to keep your dog mentally tired when it's too hot outside

One of the biggest challenges in summer is that dogs still need mental stimulation even when outdoor exercise is limited. A physically under-exercised but mentally enriched dog is significantly calmer than one who gets neither. This is where indoor enrichment tools earn their place in your routine.

Snuffle mats for calm, focused indoor activity

A snuffle mat gives your dog a foraging activity that engages their nose and brain without requiring any physical exertion or outdoor exposure. Hide kibble or small treats in the folds and let your dog sniff and search for 10-20 minutes. The focused sniffing is naturally calming and mentally tiring, often as effective as a walk for energy management.

On days when the heat makes a real walk unsafe, a snuffle mat session in the morning and again in the evening can meaningfully fill the gap.

Frozen enrichment toys

This is arguably the best summer enrichment tool because it serves double duty: it keeps your dog mentally busy AND helps cool them down from the inside. Stuffing a freezable enrichment toy and offering it frozen can keep dogs occupied for 20-30 minutes while also lowering their body temperature slightly through the cold filling.

Some of our favorite summer fillings:

Plain watermelon pureed and frozen (super hydrating, low calorie)
Low-sodium bone broth with a few blueberries frozen inside
Plain Greek yogurt mixed with mashed banana
Pumpkin and cottage cheese blend

All of these freeze well and last 20-30 minutes depending on your dog's licking style. For step-by-step recipes with exact amounts and calorie estimates, see our full frozen treat recipe guide: "10 Easy Frozen Treat Recipes for Enrichment Toys"

Indoor training sessions

Short, 5-10 minute training sessions are excellent mental exercise that require zero outdoor time. Practice basics like sit, stay, down, and recall in the cool of your home. Mental effort during training tires dogs faster than most people expect.

Keep sessions short in summer even indoors, since dogs can get warm from excitement and activity even inside.

Puzzle toys and food dispensers

Any activity that makes your dog work for their food instead of eating from a bowl adds mental enrichment. Puzzle feeders, slow feeder bowls, and food-dispensing balls are all solid options for hot days when you need your dog settled indoors.

Hydration: more important than most pet parents realize

Dogs need significantly more water in summer, but most don't drink enough on their own. A few ways to encourage better hydration:

Add water or low-sodium broth to kibble to increase fluid intake at mealtime
Place multiple water bowls in different rooms so water is always close by
Refresh water frequently. Dogs prefer cool, fresh water and drink more when it's not stale or warm
Offer frozen treats. Frozen enrichment toys made with broth or watermelon contribute real hydration alongside the mental enrichment
Consider a pet fountain. Moving water encourages more drinking in dogs who are picky about still water

Cooling tools worth having on hand

A few practical products that make a real difference on extremely hot days:

Cooling mats: Gel-filled mats that absorb body heat. Dogs can lie on them without activation needed. Great for dogs who overheat at night.
Kiddie pools: A shallow plastic pool in a shaded yard is one of the simplest and most effective cooling tools for dogs who like water. Even dogs who don't love swimming will often stand in 2-3 inches of cool water.
Cooling vests and bandanas: Wet them with cool water before walks to help dogs stay comfortable during short outdoor sessions.
Fans with air circulation: Fans alone don't cool dogs the way they cool humans (since dogs don't sweat through their skin), but they help move air and aid panting efficiency when combined with cool water or a cooling mat

Grooming considerations in summer

A common misconception is that shaving a double-coated dog (like a Golden Retriever, Husky, or Malamute) will keep them cooler. It usually doesn't, and can actually make things worse. A double coat acts as insulation in both directions, keeping cold out in winter and heat out in summer.

What does help:

Regular brushing to remove loose undercoat and improve airflow
Keeping fur clean and mat-free so air can circulate
Trimming (not shaving) fur around the paw pads where they do have sweat glands

For single-coated breeds, a trim can genuinely help. If you're unsure what's right for your dog's coat type, check with your groomer.

Summer schedule: a simple daily structure for hot weeks

Here's a practical daily routine for the hottest weeks of summer:

6:00-7:30 AM: Morning walk while pavement is still cool. Keep it shorter than your usual length and watch panting closely.

8:00 AM: Breakfast served in a snuffle mat or frozen enrichment toy to extend mealtime and add mental stimulation.

Midday: Skip outdoor activity entirely. Offer a treat dispenser toy or puzzle feeder for an indoor mental exercise session.

5:00-6:00 PM: Short training session indoors, 5-10 minutes of basic skills practice.

7:30-8:30 PM: Evening walk after pavement has cooled. Slightly longer than morning if temps have dropped.

Before bed: Another short licking or sniffing session to help your dog wind down.

This structure keeps mental and physical needs met without putting your dog at risk during peak heat hours.

Frequently asked questions

-How do I know if my dog is too hot on a walk? The clearest signs are heavy panting that gets louder over time, slowing down or stopping, and seeking shade. If your dog does any of these, stop the walk, find shade, offer water, and head home. Don't try to push through it.

-Is it safe to exercise my dog at all in summer? Yes, with timing and length adjustments. Early morning and evening walks are safe for most dogs on most summer days. The key is avoiding the 11 AM to 4 PM window, checking pavement temperature, and watching your dog closely throughout.

-Can I give my dog ice cubes to cool down? Plain ice cubes are safe for most dogs and many enjoy chewing them. Ice water is also fine. The old myth that ice causes bloat has been largely debunked, though large amounts of very cold water gulped quickly after heavy exercise is still worth avoiding for deep-chested breeds.

-My dog doesn't want to eat much in the heat. Is that normal? Yes, reduced appetite in hot weather is common and usually not a concern if it lasts just a few days. Make sure they're still drinking water. If appetite loss continues for more than 2-3 days or is accompanied by other symptoms, check in with your vet.

-What temperatures are actually dangerous for dogs? As a general guideline, walks become higher risk above 85°F with direct sun exposure and above 80°F with high humidity. At or above 90°F, most dogs do better staying indoors during midday hours. High-risk breeds (brachycephalic, overweight, senior, dark-coated) should have their outdoor time limited at lower temperatures than this.

-Do dogs need sunscreen? Dogs with light-colored fur, pink skin, or thin coats on their nose and ear tips can get sunburned. Dog-safe sunscreen (never human sunscreen, which contains zinc oxide that is toxic to dogs) can be applied to exposed areas. Ask your vet for a recommendation if your dog is at risk.

Summer is genuinely fun with dogs when you have a plan. Shift your outdoor time, lean on indoor enrichment during the hottest hours, and keep frozen treats in rotation. Your dog will stay happy, mentally stimulated, and safe even through the hottest weeks of the year.
