As summer arrives in Lebanon, Tennessee, it brings with it sunny skies, longer days—and serious heat. While many pets enjoy extra time outdoors, high temperatures can quickly turn dangerous. Unlike humans, pets can’t regulate their body temperature as efficiently, putting them at risk for heatstroke, dehydration, and a number of heat-related medical emergencies.

At Lebanon Animal Hospital, we want pet owners to feel confident and prepared during the hottest months. This guide covers everything you need to know: from recognizing signs of heatstroke, to preventing summer hazards, and understanding the potential long-term effects if your pet suffers from overheating.

Why Are Pets More Vulnerable to Heat?

They Can’t Cool Off Like We Can

Dogs and cats don’t sweat the way humans do. They rely primarily on panting and a small amount of sweating through paw pads to dissipate heat. Their fur coats—though protective—also act as insulators, which can trap heat, especially in humid climates like Middle Tennessee.

Who’s at Higher Risk?

Some pets are more susceptible to heat-related illnesses:

  • Brachycephalic breeds (like Bulldogs, Pugs, and Persian cats) have shortened airways that make it harder to breathe and cool off.
  • Overweight pets retain more heat and have reduced exercise tolerance.
  • Seniors and pets with heart, lung, or laryngeal issues are less able to adapt to temperature swings.
  • Thick-coated breeds, such as Huskies and Malamutes, may struggle more in Tennessee’s summer humidity.

Recognizing and Responding to Heatstroke

What Does Heatstroke Look Like in Pets?

Early signs of heatstroke can be subtle—but catching them quickly could save your pet’s life:

  • Heavy or rapid panting
  • Excessive drooling
  • Restlessness or seeking shade
  • Bright red gums or tongue
  • Lethargy or weakness
  • Vomiting or diarrhea
  • Staggering, confusion, or collapse
  • Seizures (a late-stage emergency)

If you suspect heatstroke:

Move your pet to a cool area, offer cool (not cold) water, apply damp towels to paws and belly, and call your veterinarian immediately.

What Happens After Heatstroke?

Can Heatstroke Cause Long-Term Medical Problems in Pets?

Yes. Even if your pet appears to recover, heatstroke can cause serious internal damage—some of which may not be obvious right away. This includes:

Organ/System Affected Possible Complications
Kidneys Acute kidney injury or failure
Liver Liver cell damage, clotting issues
Heart Irregular heartbeat, cardiac arrest
Brain Swelling, seizures, permanent neurological damage
GI tract Ulcers, bloody diarrhea, pancreatitis
Muscles Rhabdomyolysis (muscle breakdown), leading to kidney failure

What Should I Watch for After My Pet Has Recovered?

Even after treatment, monitor your pet closely for the next 48–72 hours for signs of complications:

  • Changes in urination (frequency, volume, or color)
  • Persistent vomiting or diarrhea
  • Loss of appetite
  • Lethargy or confusion
  • Labored breathing
  • Abnormal bleeding or bruising
  • Seizures or disorientation

Always follow up with your veterinarian after a heatstroke event. Bloodwork, urinalysis, and monitoring of vital signs can help detect and manage any emerging problems early.

Preventing Heatstroke: What Pet Owners Should Do

Everyday Strategies to Stay Cool

  • Hydration is key. Always provide access to cool, clean water.
  • Walk during cooler hours. Early morning or late evening walks are safest.
  • Avoid hot pavement. If it’s too hot for your hand, it’s too hot for their paws.
  • Never leave pets in parked vehicles. Cracking the window isn’t enough.
