Dog Heatstroke Deaths Rise in 2026 as Summer Temperatures Climb

A recent study published in *Scientific Reports* reviewing over 900,000 veterinary records found that roughly one in seven dogs treated for heat‑related illness did not survive. In 2025, 151 animals died from heat‑related causes and 365 were rescued; by mid‑2026, 55 deaths have already been reported (47 dogs and five cats) alongside 301 rescues.

Researchers at UNSW Sydney noted that a dog’s risk of death increases about 1 % for each degree Fahrenheit above 77 °F, spiking nearly 10 % on days above 90 °F. Veterinarians advise owners to watch for early signs such as rapid panting, excessive thirst, seeking shade, lagging on walks, or abnormal gum coloration. If symptoms worsen – bright red gums, vomiting, wobbling, or collapse – immediate veterinary care is essential.

Preventive measures include avoiding walks during peak heat, providing shade and cool (not cold) water, using damp towels on the belly and paw pads, and trimming fur around paw pads while retaining double‑coat protection. Professional grooming can help maintain coat function without shaving breeds with thick undercoats. Early intervention can mean the difference between recovery and fatality.
