Hi! I am interested in doing longer day hikes with our dog. He’s a 3 year old Hound mix and easily does 4-5 miles. I want to get him up to about 10 miles for trips every once in a while. What supplies should we take for him? What snacks would be best? How should I increase his mileage? Should I get him used to booties (I think that might be tough though)? Thanks for any suggestions and advice you have.
