Learn about your dog's limits physically, take the heat into consideration, and have a time limit for your hike. If their tongue is hanging out of their mouth more than half way, it's a sign to stop and take a rest.
I'd heard about -- and desperately wanted to try -- programs that let visitors take shelter dogs out hiking. It was a beautiful fall day, perfect for going for a hike. So my friend and I -- and my dog Murray -- stopped by a local animal shelter to pick up a dog to join us.
