Keeping dogs and cats safe in the hot weather

Hot weather is a delight for us—but our pets can struggle as temperatures rise. At Pickles Vets, we pride ourselves on offering responsible, expert guidance to help you keep your furry companions comfortable and safe.

Why Hot Weather Poses a Risk

  • Inadequate cooling systems: Dogs pant and cats groom to cool down—but both methods only go so far, especially in humid or hot conditions. Without efficient cooling, their body temperature can spike dangerously.

  • Hidden hazards: Conservatories, parked cars, and even brick or wooden outbuildings can heat up rapidly and become deadly within minutes.

  • Vulnerability of some pets: Flat-faced breeds (like Bulldogs, Pugs, and Persian cats), elderly pets, overweight animals, long-haired breeds, and those with underlying health conditions (heart or respiratory issues) are especially at risk.

Recognising Early Warning Signs

Dogs & Cats

  • Panting or noisy breathing

  • Excessive drooling

  • Lethargy, disorientation, staggering

  • Vomiting, diarrhea, collapse, seizures

  • Cats may display more subtle signs like stretching out, glazed eyes, or agitation

Heatstroke is urgent—always act fast by cooling and contacting your vet immediately.

Vet-Approved Prevention Tips

1. Avoid the Heat of the Day

  • Stick to early morning or late evening for activities. Temperatures as low as 19–20 °C can still be risky, especially for flat-faced or vulnerable pets

2. Never Leave Pets in Hot Enclosed Spaces

  • Even just a few minutes in a car, conservatory, or caravan can be fatal—even with windows open or in shade.

3. Maintain Hydration & Shade

  • Always provide fresh, cool water in multiple locations (inside and outside).

  • Freeze water bowls or use ice cubes properly: better to half-fill then freeze and top up later to keep water cool longer.

  • Set up shaded areas indoors and outdoors; ensure good airflow with fans or open windows.

4. Protect Paws and Coats

  • Avoid walking on hot pavements—test with your hand; if you can’t keep it there for 5–7 seconds, too hot.

  • Groom regularly to shed excess fur and reduce insulation.

5. Provide Cool Comfort

  • Use cooling mats, damp towels, paddling pools, or frozen treats—but supervise to prevent overcooling or water intoxication.

6. Monitor Humidity

  • Humidity hinders evaporative cooling, making heat even more dangerous. Keep pets indoors when humidity is high, even if the temperature isn't extreme.

7. Small Animals

  • Ensure hutches and cages have elevated shade and good airflow—not tightly covered. Cooling ice blocks nearby can help—but avoid letting pets chew unsafe materials. A cool damp cloth on rabbit ears helps too.

What to Do Immediately If You Spot Heatstroke

  1. Cool first, transport second—move your pet to shade or cool indoors.

  2. Gently wet their coat with cool water and use fans.

  3. Offer small sips of water if they’re responsive.

  4. Seek veterinary care immediately.

Quick-Reference Checklist (UK Vets’ Advice)

  • Walk during dawn/dusk.

  • Never leave pets in vehicles or hot enclosures.

  • Keep water cool and accessible.

  • Offer shade and airflow inside and out.

  • Test pavements before walks.

  • Groom regularly for heat relief.

  • Use cooling aids mindfully.

  • Be especially watchful during humid spells.

  • Small pets need airy, shaded shelter—not covered or confined.

  • Know heatstroke signs—act fast with cooling + vet support.


At Pickles Vets, your pets’ welfare is our top priority. If you're ever in doubt—hot or humid—it's always better to be cautious: skip the walk, offer rest in a cool spot, and remember, we're only a call away.
