Philadelphia summers are no joke — and with a major heat wave bearing down on the city, your pet’s safety should be at the top of your mind. At Love City Vet in Northern Liberties and South Philly, we see a surge in heat-related emergencies every summer, and most of them are preventable.
I put together these three tips because I want your dogs and cats to stay safe, cool, and healthy this summer — without an emergency vet visit.
Why Heat Waves Are Especially Dangerous for Pets
Unlike humans, dogs and cats can’t sweat through their skin. They regulate body temperature primarily through panting, which becomes increasingly ineffective as the air temperature and humidity rise. When a pet’s core body temperature climbs above 104°F, they’re in dangerous territory. Above 106°F, we’re talking about organ failure, brain damage, and death — and it can happen fast.
Brachycephalic breeds (think French Bulldogs, Pugs, Persian cats, and Boston Terriers) are at even higher risk because their shortened airways make panting less efficient. Senior pets, overweight pets, and those with underlying heart or respiratory conditions are also particularly vulnerable.
The good news: heat stroke in pets is almost always preventable. Here’s what I tell every pet owner at Love City Vet.
Tip #1: Know the Signs of Heat Stroke Before You Need To
The biggest mistake pet owners make is waiting until a pet is visibly in distress before acting. By then, precious time has already been lost.
Watch for these early warning signs:
- Excessive, frantic panting — more intense than usual
- Drooling or thick, ropy saliva
- Bright red or pale gums
- Lethargy or stumbling
- Vomiting or diarrhea
- Glazed eyes or confusion
If your pet is showing any of these signs, do not wait to see if they improve on their own. Move them to a cool, air-conditioned space immediately, offer small sips of cool (not ice cold) water, and apply cool wet towels to their paw pads, armpits, and groin. Then call us or head to an emergency vet right away.

Tip #2: Rethink Your Routine — Walks, Cars, and Pavement
This one seems obvious, but it’s worth repeating every single summer because we still see preventable heat injuries every year.
Pavement temperature is brutal. On a 90°F day, asphalt can reach 150°F or more. If you can’t hold your hand flat on the pavement for five full seconds, it’s too hot for your dog’s paws — and for their whole body, since dogs absorb a lot of heat from the ground up.
Timing is everything. During a heat wave, move walks to before 8 a.m. or after 8 p.m. If neither is possible, keep it short — a five-minute bathroom break instead of a 30-minute neighborhood stroll.
Cars are death traps. Even on a moderately warm day, the inside of a parked car can reach 120°F within minutes. There is no errand short enough to justify leaving a pet in a car during a heat wave. Not one.
Tip #3: Create a Cool Environment at Home
If your home doesn’t have central air conditioning — which is a lot of homes in Northern Liberties and the surrounding Philadelphia neighborhoods — you need to be proactive about keeping your pet cool.
Practical cooling strategies that actually work:
- Frozen treats: Fill a Kong or ice cube tray with low-sodium broth, wet food, or plain water and freeze it. It keeps pets busy and cools them from the inside.
- Cooling mats: Gel-based cooling mats don’t require refrigeration and can lower your pet’s surface temperature significantly. Leave one in a shaded corner of your home.
- DIY cool zones: Place a damp towel on tile or hardwood for your pet to lie on. Tile floors naturally stay cooler — make sure your pet has access to them.
- Fresh water, always: Pets drink significantly more during hot weather. Keep multiple water bowls around the house, refreshed often. Some cats prefer running water — a pet fountain can make a real difference in hydration.
- Limit activity: Indoor playtime should be low-key during a heat wave. Save the fetch sessions for cooler evenings.
A note on cats: Many cat owners assume their indoor cats are fine during a heat wave. But if your home gets hot, so do they. Cats are stoic — they’ll hide discomfort until they’re in real trouble. Make sure every room your cat frequents has proper airflow or cooling.
When To Call the Vet
You don’t need to wait until there’s an emergency to call us. If your pet seems off during a heat wave — less interested in water than usual, panting more than normal, hiding — it’s worth a call. We’d always rather answer a question over the phone than see a heat stroke case that could have been prevented.
At Love City Vet, we aim to serve Northern Liberties, Callowhill, Poplar, Old City, South Philly and all of the Philadelphia neighborhoods. We’re here for wellness visits, urgent concerns, dentals, surgeries, and everything in between.
Stay Cool, Philadelphia
Heat waves are temporary. The bond you have with your pet is not. A little extra care this week can make all the difference — and if you ever have a doubt, don’t hesitate to reach out to us.
Stay safe out there, Philly.
