During extreme heat, our bodies cope by sweating. Dogs cope by excessively panting and dispelling heat from their paws. If a dog’s internal body temperature rises above 106ºF, damage to the organs may become permanent and irreversible. During the summer it is imperative to check your dog for signs of heat stroke which include:
Difficulty breathing
Excessive panting
Mucous membrane is redder than normal
Disorientation
Increased heart rate
Thick saliva
Vomiting
Bloody diarrhea
Collapse
Rectal temperature over 104º

If you suspect that your dog may have heat stroke:
Move your dog out of direct heat.
Take rectal temperature.
Gently hose cool water over your dog (Do NOT use ice packs or icy water)
Soak towels with cool water and place them over the dog’s head, feet, neck, chest, and abdomen.
Place a fan over the dog.
Call your vet or transport dog to the nearest emergency vet.

Dogs that are highly susceptible to heat stroke include:
Dogs with a brachycephalic face (short noses) such as Bulldogs, Pugs, Boxers, Pekingese.
Puppies
Senior dogs
Overweight dogs
Dogs with thick double-coats

Keep in mind that in this “concrete jungle where dreams are made of” the sidewalks and streets are extremely hot to your dog’s paws. Here are some tips to prevent heat stroke.
NEVER leave your dog in a parked car.
Avoid strenuous exercise on hot days.
Walk in shade and offer water to your dog.
Walk during morning and evenings.
Look into canine cooling coats.
Keep the AC running for your pet while you’re out.
If it is too hot to walk home, hail a cab. Most cabbies will let you carry your pup on your lap but be sure to tip them well.
