Dogs can succumb to heat stroke very quickly in warm and humid weather because the only way dogs releases heat is by panting and sweating through the foot pads and nose. Prevention is key. Avoid vigorous exercise on hot days, keep your dog hydrated and do not leave him/her alone outside or in a warm space (eg car). That said, if you notice any of these signs in your dog or someone else's, they may be suffering heat stroke....
Vigorous panting
Dark red gums
Dry gums
bloody vomiting or diarrhea
lying down and unwilling or can’t get up
staggering gait
collapse and/or loss of consciousness
thick saliva
seizures
If the dog is suffering heat stroke:
move the dog out of the heat
cool them off with a shower or tap water or place cool wet rags on their footpads and head. Do NOT use ice cold water - this can actually harm the dog further.
offer the dog water but don’t force him/her to drink.
call or visit the vet right away.
Note: Certain types of dogs are more sensitive to heat especially elderly dogs, overweight dogs and brachycephalic (short-nosed) breeds, like Pugs, Bulldogs, Cavalier King Charles Spaniels, Boxers and even Staffies. Take extreme precautions with these breeds during summer.
