NEVER use cold water on a dog with heat stroke as this can cause SHOCK and death.
use luke warm/ cool (NOT COLD) water.
while your dog is feeling better, i wanted to post this for anyone else who may be reading or if this ever happens again.
if you want to encourage your dog to drink, add some salt free chicken or beef broth (dont use boullion or cubes use REAL broth) and mix it with the water.
dogs general loose most of there body heat thru the ears and feet, so the next time this happens take your dog imedietly into the bath tub and fill with luke warm/cool water (remember a dogs body temps are higher then ours, so what luke warm water is to us is much cooler to them) rub (dont dump or pour!) some of the water onto the outside of the ear to help it cool while keeping the feet and part of the legs submerged. you can poor water over the back ect.
if your in a place where you dont have access to a tub, grab a bottle of water and rub onto the ears and pour onto the feet and legs
again PLEASE dont dump ice cold or cold water onto a dog whos suffering heat stroke as this CAN cause shock and death...
