Thanks for the reply. I have noticed a lot of their limitations too. We do hike and camp a lot with our two labs. Obviously we wouldn't bring the bulldog hiking, but I was thinking that when camping we could provide ample shade, water and maybe a cooling battery powered fan for him. We want a third dog, but I don't have it in me to raise another ultra high energy breed puppy right now. I live in CO, and we do get hot summers, but only a couple months worth. There are really only a few camping trips a year that we encounter heat.
