Camping tips and tricks

My dad and I really enjoy backpacking/hiking with our golden retriever. I was planning on buying a lot of cool gear for him to use when we go this Spring/Summer, but I need help with ideas on what to buy that he could really use. So far, I plan on getting him a big water bottle and some stuff for our dog to use, but what else could I get?
Websites with pictures or information would be great! Thank you.

Leatherman makes a mini version of their fine tool - I just received one from my family - great tool.
Also the small headlights(elastic band that goes around your head with LED lights)
gloves that have windstopper protection

Make the water bottle one of the Nalgeine style with screw off lids

all these items should be in stock at your local Sports Chalet and at a reasonable price.
