Heatstroke is one of the most lethal yet most misunderstood emergencies in veterinary medicine—and it doesn’t only happen on scorching summer days.

In this in-depth episode Robyn from Vet Voices on Air is joined by two leading voices in the field: Dr Emily Hall, primary care vet, educator, and researcher whose PhD focused on the epidemiology of heatstroke in UK dogs, and Emily Cockerill, referral RVN and Lowland Rescue search dog volunteer with extensive real-world experience managing dogs working in extreme conditions.

Together, they unpack what heatstroke actually is, why it’s so dangerous, and why time and temperature matter more than almost anything else. Using clear, evidence-based explanations, they explore what happens inside the body when temperatures rise—how proteins “cook,” organs fail, and why once a critical threshold is crossed, the damage is irreversible.
