Invaluable advice on this podcast:
● Cold water WILL NOT SHOCK your overheated dog
● A dog will die at 45°C, so if suffering heat exhaustion, get them wet before the vet.
● Lemon juice DOES NOT help with brachycephalic breeds, being acidic, it only exacerbates an already swollen throat!
It's getting hot, hot, hot... so let's share some heatstroke information!
Too Hot to Handle: The Truth About Canine Heatstroke
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.
The conversation tackles long-standing myths head-on, including:
The belief that cold or ice water causes “shock”
➡Why wet towels can worsen overheating
➡The dangers of lemon juice in brachycephalic dogs
➡Misconceptions around double-coated breeds and clipping
➡Why ice cubes might not meaningfully cool dogs but can be used for indoor and cool enrichment
Crucially, the episode highlights that exertional heatstroke is the most common cause, not hot cars—and that heatstroke can occur in winter, during travel, stress, anaesthesia recovery, or even inside veterinary practices. Certain breeds and health conditions increase risk, but any dog (or cat, rabbit, or other small animal) can be affected if heat production exceeds the body’s ability to lose it.
Listeners will come away with clear, practical guidance on:
➡Recognising early and late signs of heatstroke
➡What owners should do immediately at home or in the field
➡Why pre-cooling before transport dramatically improves survival
➡Current best-practice protocols for active cooling in clinic
➡When to start and stop cooling based on body temperature
➡How prevention, timing, and informed decision-making save lives
If you’ve ever wondered when it’s too hot to walk your dog, how heatstroke presents beyond “just panting,” or what the evidence really says about cooling, this episode is essential listening—for veterinary professionals and pet owners alike.
Because when it comes to heatstroke, minutes matter—and myths can kill.
