dog overheated is he going to be ok?

I had a pitbull that I worked during the summer a couple of years back that got way too hot (dog could not stand on his own) and he never fully recovered. He was heat sensitive after that. I worked him in the fall and winter a couple of times after that and he was fine, but couldn't do it during the warm weather. I had a catahoula dog that overheated and he made a full recovery. He didn't get nearly as hot as the pitbull dog did though. He could stand but was pretty wobbly. If it was me I would get the dog past the dehydration stage and let him lay up and relax until the fall and the cooler weather and then ease him back into it and see how he does.
