It is finally time. I have waited MONTHS to be able to do this with him and I am SOOO excited. We now have the backpack, and little booties and everything else we need to go backpacking on the A.T. for the weekend. He seems to really like his pack, and behaves better with it on for some unknown reason.(he does really well otherwise but it seems like he has more purpose with it on) The pack is really big looking but he can only carry about 10lbs if that. The smaller one down was too small so we had to go with the next size. I'm thinking of packing a few pillows or something to fill out the pockets for him and give him something soft to sleep on after a long day on the trail. Doesn't he look snazzy?
