A dog may come inside after playing and spend a few minutes panting beside the water bowl. Usually, that is simply how the body cools down. However, panting that becomes intense, unusual tiredness, or a refusal to drink can signal that the summer heat is becoming more than your dog can safely handle.

National Pet Hydration Awareness Month offers a useful reminder during July, when heat and humidity can make walks, backyard play, and car trips harder on dogs. Recognizing the difference between normal cooling and early overheating can help you respond before your dog’s condition becomes more serious.

When Normal Panting Starts to Look Different

Dogs rely primarily on panting to release heat. After exercise or time outdoors, their breathing should gradually settle once they rest in a cool space and have access to fresh water.

The concern begins when panting continues or becomes more forceful despite rest. According to the American Veterinary Medical Association’s warm-weather pet safety guidance, hot and humid conditions can place pets at risk even when the day does not seem dangerously warm to their owners.

Watch how your dog behaves as well as how they breathe. A dog who is simply warm may seek shade and take a break. A dog who is overheating may appear restless, struggle to get comfortable, or lose interest in activities they normally enjoy.

Early warning signs may include:

• Heavy, rapid, or frantic panting

• Excessive drooling or unusually thick saliva

• Seeking shade or repeatedly lying down

• Reluctance to walk, play, or continue exercising

• Unusual tiredness or weakness

• Increased thirst

• Dry or sticky gums

• Loss of appetite

• Acting anxious, restless, or unlike themselves

These changes can be easy to dismiss after a busy afternoon. Still, a dog who is not recovering normally deserves close attention.

Signs That Overheating Is Becoming an Emergency

Heatstroke occurs when a dog’s body temperature rises to a dangerous level and the body can no longer cool itself effectively. The Cornell University Riney Canine Health Center describes heatstroke as a life-threatening medical emergency that can affect multiple organs.

More serious warning signs include:

• Labored or noisy breathing

• Bright red, dark red, pale, or bluish gums

• Vomiting or diarrhea

• Confusion or disorientation

• Stumbling or difficulty standing

• Severe weakness

• Tremors or seizures

• Collapse or loss of consciousness

Do not wait to see whether these signs improve on their own. Begin moving your dog to a cooler environment and contact a veterinarian immediately. If the clinic is closed, go to the nearest emergency veterinary facility.

Why Some Dogs Overheat More Quickly

Any dog can become overheated, but certain pets need extra protection during warm weather. Short-muzzled breeds have less efficient airways for cooling through panting. Older dogs, overweight pets, puppies, and dogs with underlying heart or respiratory problems may also have more difficulty regulating body temperature.

Risk may increase for:

• Bulldogs, Pugs, Boxers, and other short-muzzled breeds

• Senior dogs

• Puppies

• Overweight dogs

• Dogs with thick or double coats

• Dogs with heart or breathing conditions

• Dogs that are not accustomed to warm-weather activity

• Highly active dogs that continue playing despite fatigue

Additionally, humidity matters. Panting cools the body through evaporation, so high humidity can make that process less effective. A walk that felt comfortable earlier in the season may become too demanding once summer conditions change.

Rather than relying on a fixed amount of exercise, pay attention to your individual dog. Their pace, breathing, and willingness to continue provide valuable clues.

What to Do if Your Dog Seems Too Hot

Responding early may keep mild heat stress from progressing. First, stop all activity and move your dog into an air-conditioned room or a shaded, well-ventilated area.

Then:

• Offer small amounts of cool, fresh water

• Wet your dog with cool, not ice-cold, water

• Use a fan to improve airflow if one is available

• Keep your dog calm and limit movement

• Call your veterinarian for guidance

Avoid covering your dog with wet towels for an extended period because the towels can trap body heat as they warm. Ice baths and extremely cold water may also interfere with gradual cooling. Most importantly, do not force water into the mouth of a weak, confused, or unconscious dog.

Even when a dog appears to improve after cooling, veterinary guidance is important when the panting was severe or other symptoms developed. Internal complications may not be immediately visible.

When Your Dog Needs Same-Day Veterinary Care

Not every tired dog has heatstroke. Panting and lethargy can also occur with pain, illness, toxin exposure, heart or respiratory problems, and other medical conditions. Therefore, the circumstances and accompanying symptoms matter.

Call Bellaire Animal Medical Center if your dog develops concerning symptoms such as:

• Severe or repeated vomiting or diarrhea

• Lethargy that does not improve with rest

• Refusal to eat or drink

• Sudden behavior changes

• Weakness or difficulty moving

• Loss of consciousness

Bellaire Animal Medical Center offers same-day pet urgent care in Nicholasville for serious concerns that need prompt attention but are not immediately life-threatening. The team can evaluate your dog, perform appropriate diagnostics, and begin treatment.

In-house digital X-rays and on-site laboratory testing allow the veterinarians to gather important information during the same visit in many cases. For collapse, severe breathing difficulty, seizures, loss of consciousness, or other life-threatening signs, seek emergency veterinary care immediately.

Simple Ways to Prevent Heat and Dehydration

Prevention often comes down to adjusting familiar routines. Walk your dog during the cooler morning or evening hours, keep water available indoors and outdoors, and build in frequent rest breaks.

The National Weather Service Louisville heat safety guidance recommends providing pets with hydration, shade, and access to an air-conditioned space whenever possible.

Dogs should also never be left inside a parked vehicle. The AVMA’s pet safety information for vehicles explains why temperatures inside a car can rise rapidly, even when the weather does not feel extreme and the windows are partly open.

A few practical habits can make summer safer:

• Carry water and a portable bowl on walks or outings

• Choose shaded routes

• Shorten exercise sessions during hot or humid weather

• Check pavement before allowing your dog to walk on it

• Never leave your dog unattended in a parked car

• Bring outdoor dogs inside during the hottest part of the day

• Watch senior dogs and short-muzzled breeds especially closely

• Allow your dog to stop rather than encouraging them to keep going

Summer fun should not require your dog to push through exhaustion. When they slow down, seek shade, or hesitate to continue, listen to them.

A little panting after activity may be normal, but persistent panting, unusual tiredness, vomiting, weakness, or refusing water should not be ignored. Acting promptly can make a meaningful difference when a dog is struggling with the heat.
