So I'm new to this sport (but not new to heat exhaustion-my own experience or veterinary medicine-I am a vet). I can't imagine denying a dog water when they need it....
I have a hard time in the summer heat with my dog (and it rarely hits 80 here) because he doesn't want to stop for water. I have to make sure he rests, drinks and gets cool. If he told me he had to drink and cool off, I'd be sure that he got the chance.....
If a dog is quitting and running to the water when they shouldn't, it seems there are bigger holes in your training that you need to worry about.....
