How to Keep Dog Cool in Summer

Dogs can't sweat efficiently — they cool themselves primarily through panting, which becomes less effective as temperatures and humidity rise. Heatstroke can develop in minutes and can be fatal. Keeping your dog cool in summer isn't optional — it's a matter of life and death. Here's everything you need to know.

What You'll Need

• A self-cooling mat: The Green Pet Shop self-cooling mat uses pressure-activated non-toxic gel to keep your dog cool indoors and outdoors. No water or refrigeration needed — place it in your dog's rest area for instant cooling relief. Available for dogs 46–80 lbs.
• A dog water bottle: A portable dog water bottle with bowl is non-negotiable in summer. Offer water every 10–15 minutes during outdoor activity.
• Dog boots: QUMY dog boots protect paws from hot pavement — asphalt can reach 140°F (60°C) on a hot day, causing severe burns in seconds.
• A dog life jacket: An Outward Hound dog life jacket for swimming — one of the best ways to keep dogs cool and exercised in summer.

Signs of Overheating: Know Them Cold

Act immediately if you see these signs:

• Excessive, heavy panting that doesn't slow down
• Drooling more than usual
• Bright red or pale gums
• Vomiting or diarrhea
• Stumbling, weakness, or collapse
• Glazed eyes or confusion

If you suspect heatstroke: Move to shade or air conditioning immediately, apply cool (not cold) water to the body, offer small amounts of water, and get to a vet immediately. Heatstroke is a life-threatening emergency.

How to Keep Your Dog Cool Indoors

Air Conditioning

The most effective way to keep your dog cool. Keep your home air-conditioned during hot weather. If you don't have AC, use fans and keep blinds closed during the hottest part of the day to reduce indoor temperature.

Cooling Mat

Place a self-cooling mat in your dog's favorite rest area. The pressure-activated gel absorbs body heat and keeps your dog cool without electricity, water, or refrigeration. Ideal for dogs that lie in warm spots or near windows.

Cool Water Access

Ensure fresh, cool water is always available indoors. Add ice cubes to the water bowl on very hot days. Change the water frequently — warm water is less appealing and less effective at cooling.

Frozen Treats

Frozen treats — frozen Kongs, frozen broth cubes, frozen blueberry yogurt bites — provide cooling relief and mental enrichment. See our guide on how to make frozen dog treats for easy recipes.

How to Keep Your Dog Cool Outdoors

Timing: Exercise Before 9 AM or After 7 PM

The most important outdoor cooling strategy. Avoid outdoor exercise during peak heat hours (10 AM–6 PM). Early morning and evening walks are significantly cooler and safer.

Pavement Temperature Check

Before any walk, hold your hand on the pavement for 5 seconds. If it's too hot for your hand, it's too hot for your dog's paws. Use dog boots or walk on grass instead.

Shade

Ensure shade is available at all times in your yard. A dog in direct sun on a hot day can overheat in minutes. Trees, shade sails, and covered areas all provide effective shade.

Swimming

Swimming is the ideal summer exercise — it's cooling, low-impact, and most dogs love it. Use a life jacket in open water or for dogs new to swimming. A shallow paddling pool in the yard provides cooling play without the risks of open water.

Sprinkler Play

A garden sprinkler gives dogs a way to cool down while playing. Many dogs love running through sprinklers. Keep sessions in the shade.

Hydration on the Go

Bring a portable water bottle on any outdoor outing. Offer water every 10–15 minutes during active outdoor time in summer. Never leave home without water in hot weather.

Never Do These in Summer

• Never leave your dog in a parked car — temperatures can reach fatal levels within minutes, even on mild days with windows cracked
• Never exercise during peak heat hours (10 AM–6 PM)
• Never walk on hot pavement without checking the temperature first
• Never leave your dog outside without shade and water

Breeds That Need Extra Care in Heat

• Brachycephalic breeds: Bulldogs, French Bulldogs, Pugs, Boxers — their shortened airways make panting less effective
• Dark-coated breeds: Absorb more heat from sunlight
• Overweight dogs: Extra weight makes thermoregulation harder
• Senior dogs and puppies: Less efficient at regulating body temperature

Final Thoughts

Keeping your dog cool in summer requires a cooling mat indoors, early morning or evening exercise outdoors, constant water access, pavement temperature checks, and swimming as the ideal hot-weather activity. Know the signs of heatstroke and act immediately if you see them. With the right precautions, summer can be a wonderful season for you and your dog.
