Long summer days invite backyard barbecues, trail adventures, and porch lounging with our pets—but rising temperatures can turn fun into danger faster than many people realize. Heat stress, dehydration, and burned paw pads are common warm-weather problems veterinarians see every year. At Heritage Animal Hospital, we help pets across Sterling, Herndon, Sterling Park, and nearby Northern Virginia communities stay healthy through the hottest months, and we’ve gathered practical, vet-informed tips to keep your furry family safe all season long.

1. Why Heat & Hydration Matter More Than You Think

Pets don’t cool themselves as efficiently as humans. Dogs rely mainly on panting, while cats are even more subtle in showing discomfort. When heat and humidity climb, body temperature can rise quickly—especially in thick-coated breeds, flat-faced (brachycephalic) dogs and cats, seniors, and overweight pets.

Providing shade, airflow, and fresh, cool water can dramatically reduce the risk (AVMA: Warm Weather Safety). Cats benefit from quiet, ventilated spaces away from direct sunlight—think a cool basement or a room with fans.

Even “mild” outdoor temperatures can become dangerous in certain environments. Asphalt and concrete store heat and can burn paw pads, while enclosed spaces such as vehicles or small sheds can reach deadly temperatures within minutes(CDC: Heat and Pets).

2. Spot the Warning Signs: Heat Stress, Heatstroke & Dehydration

Early recognition saves lives. For dogs and cats, watch for:

• Heavy or rapid panting that doesn’t settle (yes, cats can pant under stress).
• Excessive drooling (more common in dogs, but cats may salivate too).
• Lethargy, wobbling, or collapse.
• Vomiting or diarrhea.
• Dry gums and refusal to drink water.

Cats tend to hide illness, so subtle signs—such as avoiding warm spots or seeking cool tile floors—deserve attention. Offer water immediately and move your pet to a cooler place; if symptoms persist, contact us for urgent care. 

3. Smart Daily Habits to Beat the Heat

Small adjustments to your routine go a long way:

✔ Time Outdoor Activity Wisely
Dogs should walk early or late when surfaces are cooler. Cats that spend time on balconies or screened porches should be supervised and provided with shade.

✔ Protect Paws
Hot pavement can burn. Test with your hand before walking your dog (Humane Society Guide).

✔ Hydrate Everywhere
For dogs, carry water on walks. For cats, provide multiple bowls or even a pet fountain to encourage drinking 

✔ Create Cool Retreats
Fans, cooling mats, and air-conditioned rooms help both species. Cats appreciate elevated perches in breezy areas and tiled floors in shaded spaces (ASPCA Summer Safety).

✔ Never Leave Pets in Parked Vehicles—Ever
Even “just a minute” can be fatal. Temperatures soar in enclosed cars—even with windows cracked (NOAA Heat Safety).

4. Higher-Risk Pets & Special Situations

Some pets need extra caution:

• Flat-Faced Breeds & Cats (Pugs, Bulldogs, Persians) overheat faster.
• Thick-Coated Pets: Brush regularly to remove undercoat—don’t shave without consulting your vet.
• Senior Pets & Those with Heart Disease: They struggle with temperature regulation.
• Cats Indoors Only? They still need cool areas and fresh water—avoid sun-facing windows during peak heat.
• Travel & Camping: Bring clean water and shade—avoid natural bodies of water (ASPCA Camping Tips).

5. First Steps If You Suspect Heatstroke

Act fast—heat illness escalates quickly:

1. Move your pet to shade or AC.
2. Offer small sips of cool water (not ice cold).
3. Apply cool, damp towels to the neck, belly, and paws (Red Cross Pet Heat Safety).
4. Call your veterinarian immediately—complications can develop even if your pet seems better.
