Overview

• Dogs Trust, RSPCA and regional charities have reiterated key signs of heat exhaustion—heavy panting, drooling and collapse—and advise owners to “cool first, transport second” at the first warning of distress.
• A viral Hello Collar clip urging owners to watch for tongue changes—elongation, thickening, reddening or curling—has been widely adopted as an informal early-warning cue.
• Flat-faced breeds, older or overweight dogs and those with pre-existing conditions face heightened danger when temperatures approach or exceed 30 °C.
• Insurer research shows pavements can reach 50 °C and artificial grass up to 65 °C during heatwaves, prompting experts to recommend the five-second pavement test, shaded routes and regular water breaks.
• Owners are urged to adjust walks to cooler hours, provide shade or cooling mats, carry fresh water and never leave dogs unattended in vehicles to reduce emergency admissions.
