Aka Steve. Our dog trainer has been away and we’ve been taking a break!! I love getting up in the mountains and luckily for me, so does this guy. I am also loving his dog pack. I got the large size and it is still really big (Steve’s only 65lbs) But he should grow into it nicely. This is the palisades pack from Ruffwear (they make great dog stuff) I have these for both dogs. My female, Lexi has had hers for five years. They hold up great. I use the packs for walking at home too, gives an added workout and gives them a job to do.
