Lillian New York, New York 7/21/2013 1:27:26 PM My dog had heatstroke a few days ago. We were able to cool him down right away but and took him to the vet yesterday. His temp was normal, he is eating and drinking but is somewhat lethargic....is this normal? He is now in a cool place and drinking normally. Does it take several days to get over the effects of heat stroke?
