Late May is when many places start to feel like summer, and that means one big thing for pet parents: heat safety. Heat Safety Week (May 18–22, 2026) is a reminder that dogs and cats can overheat fast, especially around hot cars, sunny sidewalks, and humid afternoons.
This guide shares practical hot-weather tips you can use all season—plus a few easy outfit ideas for pet-friendly errands, park hangs, and backyard get-togethers (think Memorial Day weekend vibes). If you love showing off your pet-parent pride, we’ll also point you to a few TooCutePets collections that fit the moment without feeling “salesy.”
Heat Safety Week 2026: the dates (and why it matters for pets)
Heat Safety Week 2026 runs May 18–22, and the National Weather Service uses it to highlight heat-related hazards and prevention tips.
One pet-specific reminder is especially important: pets can die of heat stroke in as little as 15 minutes in a hot car, and cracking the windows doesn’t help. When it’s warm, the safest move is to keep pets at home or bring them with you only when you can stay with them the whole time.
If you want to share these reminders with friends and family, you can reference official Heat Safety Week information from the National Weather Service and the Heat Safety Awareness Toolkit from APHA/NIHHIS (both include pet-and-vehicle safety guidance).
The most searched summer question: “Is it too hot to walk my dog?”
Instead of guessing, use a simple routine that’s easy to remember:
- Check the surface. Touch the sidewalk/asphalt with your hand for several seconds. If it’s too hot for you, it’s too hot for paws.
- Time your walks. Aim for early morning or later evening when the sun is lower.
- Pick shade. Choose routes with trees, grass, or dirt paths when possible.
- Bring water. For you and your pup—especially on longer walks or humid days.
For cats who enjoy a harness walk or stroller ride, the same logic applies: shade, shorter outings, and water breaks are your best friends.
Hot-car safety: the “quick errand” that isn’t quick
Heat builds inside cars rapidly. The National Weather Service stresses that cracking the windows doesn’t help and that pets can succumb to heat stroke in as little as 15 minutes.
If you’re running errands, consider these safer alternatives:
- Do curbside pickup when possible.
- Bring a friend so one person can stay with the pet.
- Leave your pet at home for errands that require going inside.
Signs of overheating in dogs and cats (and what to do)
Every pet is different, but overheating often shows up as:
- Heavy panting (dogs), open-mouth breathing (some cats)
- Drooling, bright red gums, or a very fast heartbeat
- Weakness, wobbliness, vomiting, or collapse
If you think your pet is overheating, move them to shade or AC, offer cool (not ice-cold) water, and call your veterinarian or an emergency clinic right away.
Summer-ready pet parent outfits: cute, comfortable, and practical
Heat-safe pet parenting also means dressing for the day so you can stay out longer (and safely). Here are a few outfit ideas that work for dog walks, patio brunches, and pet-friendly events:
1) The “morning walk uniform”
- Light layer for early starts (grab a cozy but breathable hoodie)
- Comfortable shoes you can actually walk in
- Hands-free essentials (keys, phone, poop bags, treats)
If you love playful pet art, start with our illustrated looks like Pets in Sunglasses or Pets in Hats—they’re an easy conversation starter at the park.
2) The “dog-friendly patio” outfit
- A soft, breathable t-shirt
- Sunglasses + a hat for you (shade counts)
- A tote you can throw anything into (try our tote bags)
Bonus: if your dog is a social butterfly, a tote is perfect for packing a small water bowl and a towel for drool or muddy paws.
3) The “evening neighborhood stroll” look
- A comfy sweatshirt for cooler temps after sunset
- Reflective gear if you’re out later
- Water for you both—evening walks can still be warm
Breed-specific heat tips (and cute ways to represent your favorite)
Some breeds are more heat-sensitive than others (especially flat-faced breeds and heavy-coated pups). Two things help almost everyone: shorter outings and more shade breaks.
Want to rep your best friend while keeping things fun and light? Here are a few fan-favorite collections to match your crew:
- French Bulldog Collection (flat-faced friends appreciate extra cool-down time)
- Husky Collection (fluffy coats + warm days = plan early walks)
- Golden Retriever Collection (perfect for “lake day” energy)
- Tabby Cat Collection (for the sunbeam-loving household)
- Maine Coon Collection (big floof, big personality)

Memorial Day weekend: easy, pet-safe plans
Memorial Day weekend often brings cookouts, travel, and outdoor time. A few pet-friendly reminders:
- Shade + fresh water in the yard or at the park.
- Cool-down breaks indoors during the hottest part of the day.
- Travel smart: never leave pets in the car while you “just run in.”
Heading to a friend’s place? Toss essentials into a tote and keep your outfit simple. A cute pet-themed tee and a roomy tote are low-effort, high-comfort—and you’ll be ready for anything.

Takeaway: make heat safety part of your routine
Heat safety isn’t about fear—it’s about a few smart habits that keep your dog or cat comfortable all summer long. Stick to cooler walk times, avoid hot cars entirely, and plan shade and water like it’s part of the outing (because it is).
