Summer in Houston, Texas brings long days, sunshine, and plenty of opportunities to enjoy the outdoors with your pets. But along with the fun comes a serious responsibility: protecting your pet from dangerous heat-related illnesses. Unlike humans, dogs and cats can’t sweat to cool off, making them highly vulnerable to overheating—even during brief periods of heat exposure.

This guide covers the risks, signs, and consequences of heat-related illnesses in pets, plus actionable strategies to keep them cool, safe, and healthy all summer long.

Why Summer Heat Is So Dangerous for Pets

Pets Can’t Cool Off Like We Can

Humans sweat across most of the body, but pets primarily regulate their temperature through panting and minimal sweat from their paw pads. Their fur also traps heat—especially in humid environments like Houston—making it even harder to cool down.

High-Risk Pets

Certain pets are especially vulnerable to heat-related illness:

Recognizing Heatstroke in Pets

Early Signs to Watch For

  • Excessive panting or drooling
  • Seeking shade, slowing down, or reluctance to move

  • Disorientation, weakness, staggering
  • Collapse or seizures

What Happens After Heatstroke?

Even if your pet appears to recover quickly, the danger doesn’t end once they cool down.

Potential Secondary Complications:

  • Kidney failure from dehydration or overheating
  • Liver damage due to poor oxygen circulation during overheating
  • Bleeding disorders or clotting issues
  • Neurological damage including confusion or seizures
  • Respiratory distress in the days following the event

That’s why veterinary care is essential—not just for cooling, but for monitoring and supporting organ recovery in the days that follow.

Heatstroke Prevention: Smart Summer Habits

Hydration and Shade Are Non-Negotiable

  • Always offer clean, cool water—indoors and out.
  • Create shaded rest spots when your pet is outside.
  • Use cooling mats or damp towels to help your pet regulate body temperature.

Exercise Wisely

Never Leave a Pet in a Parked Car
