Alcaracu, we do a lot of hiking as well and we are looking forward to taking the pup with us. We have started walking with her now and she does very well on the leash. Our biggest problem is the snow and bitter cold we have been dealing with making it difficult to get the longer walks in that we would like. Regardless of the weather we have been getting her out a couple time a day just for a good walk.
Most of the time the crate barking is not an issue and quite often if she is very tired she will go to the crate on her own for a nap. The barking usually occurs when we take her out for a bathroom break just before we leave and then have to crate her when the very cold weather has fully revved her up.
As far as not crating or jailing as some would say, if you have nothing to do but watch a pup every waking moment and never leave the home I guess you could get away with that. Quite frankly I would call leaving a pup unattended and running loose in the house very irresponsible. There are way too many hazards that could injure or kill an unattended pup. She is treated very much like a member of the family and the limited amount of time that someone cannot be home to be with her, she will be safely crated.
