How Do I Keep Pets Cool in Summer and Warm in Winter at Home?

The short answer: Pennsylvania's summers and winters both push pets past their comfort zone, so homes need a plan for heat and cold that keeps pets safe when you are home and when you are not. Pets regulate temperature differently than people. Dogs and cats cool themselves mainly by panting and through their paw pads, and they can overheat in conditions that feel fine to us. In winter, short-coated and senior pets struggle in the cold, and outdoor time needs limits. A few simple home habits prevent the emergencies that send pets to the vet.

Know the Danger Signs

Heatstroke signs include heavy panting, drooling, weakness, vomiting, and collapse; cool the pet gradually and call the vet immediately. Hypothermia signs include shivering, lethargy, and pale gums; warm the pet slowly and seek vet care. Knowing these signs before you need them is the difference between a close call and a tragedy. Never leave a pet in a parked car, in any season, because cars heat and cool to dangerous extremes quickly.

In summer, the home should stay cool enough that a pet left inside is comfortable all day. Keep the thermostat at a reasonable setting, use fans to move air, and close curtains on the sunny side to block heat. Provide fresh, cool water in multiple spots, and consider a pet fountain, which encourages drinking. If the pet spends time outdoors, ensure shade and water in the yard, as covered in our guide on safe outdoor spaces, and limit outdoor time to the cooler parts of the day.

Hot Floors and Heat Sources

Check the surfaces your pet walks on: dark pavement and unshaded decks can burn paw pads in summer. Keep pets off hot asphalt and consider paw-friendly surfaces in the yard. If the power goes out in a heat wave, have a plan: a cooler room, a battery fan, or a friend's home with air conditioning. A smart thermostat and temperature sensor, covered in our guide on smart devices for pets, can alert you to failures while you are away.

In winter, pets need warm, draft-free sleeping spots and limited outdoor time. Place beds away from drafty windows and doors, and add blankets or a heated pet bed for older and short-coated pets, following the manufacturer's safety guidance. Keep the thermostat at a consistent setting, and be careful with space heaters, which can burn curious pets; choose models with tip-over shutoff and keep them out of reach. Check the floor temperature, because cold floors drain body heat from pets who lie on them.

Outdoor Limits and Winter Hazards

Limit outdoor time in extreme cold, and watch for shivering, lifting paws, and reluctance to walk, which mean the pet is cold. Wipe paws after walks to remove road salt and ice-melt chemicals, which are toxic if licked, and check for cracked paw pads. Antifreeze is a winter hazard in garages and driveways, so store it out of reach and clean up spills, as noted in our guide on pet-proofing a new home.

Run a seasonal home check twice a year, before the first heat wave and before the first freeze. In spring, check window screens, test the air conditioning, and inspect the yard for hazards after winter. In fall, check heating systems, test carbon monoxide detectors, and inspect the furnace area, because pets like to nap near furnaces and can be exposed to drafts and hazards. Our guide on winterizing your home covers the house side, and cooling your home efficiently covers the summer side.

If you are buying a home, ask about the HVAC age and condition, because a failing system is a pet emergency waiting to happen. If you are selling, a well-maintained HVAC and good insulation are selling points for pet owners and everyone else.

Seasonal extremes complicate travel, so plan pet care around the weather. In summer, confirm your sitter or boarding facility has air conditioning, and avoid leaving pets in transit during the hottest hours. In winter, check that the pet's travel crate is warm and that the car is preheated before a trip. If you board, ask about the facility's temperature control and emergency plans, because a power outage in a heat wave or freeze is a real risk.

The Home Check Before You Leave

Before any trip, verify the thermostat setting, check that the HVAC is serviced, and leave your sitter with the vet's number and a written care sheet. A smart thermostat and temperature sensor, covered in our guide on smart devices for pets, let you monitor the home remotely and catch problems early.
