Does anyone else enjoy hiking with their dogs or back packing? How do the dogs like it? I got a couple of doggy back packs for the pups to carry their own things in, the came in the male today and I noticed that when Diesel is packing, he doesn't pull on the leash and sticks close. It doesn't make any sense to me but he seems to enjoy packing. I've always heard it's good to give them jobs. So anyone else have dogs who enjoy packing/hiking? Any tips on what to bring along? What type of packs are best?
