Dog peeing issue + other

Question
I just recently got a puppy and am fully aware that it takes a lot of time to
train a puppy (and patience). I am currently dealing with the issue that my
husky puppy will pee on the floor almost right after coming home from a
long walk (anywhere from 45 minutes to 2 1/2 hours depending on the time)
and I am not sure why he wont go outside. He has gone outside before, but is
regularly going on the floor, sometimes like 10 minutes apart, while other
times he can hold it for hours. So at this point I'm not really sure how to best
go about training him to pee outside. He gets tons of walks and tons of
attention. I have also tried crate training, which hasn't been working (plus the
breeder I got my husky from said that huskies don't crate train very well and
tend to freak out causing unneeded amounts of stress. So far he goes into the
smallest room we have with towels and paper on the floor, when we are not
home. So, that was a handful of information, but I really would like some
help!!!
Thank You!!!

Answer
Some dogs won't go outside because they have been scolded for "mistakes" indoors, and they learn to fear pee'ing in front of the human while they are leashed.  Or, you may not be cleaning mistakes with an enzymatic cleaner, so he is still attracted by the smell of his urine.  (Use Petastic or simple Solution to clean up with)
The key to good house training is:
Never lose sight of the pup while he is out of his crate.  
Crate when you can't watch - OR, in the case of dogs that don't crate well, tether the dog to you at all times, so he can't get away with peeing indoors without you seeing him.
If the dog has an accident, do NOT scold.  Instead, simply say, "Outside?"  (a question is better than harshness, and will eventually become a cue that you can use when he even looks like he has to go)
Take the pup out more often than you think you have to, and be sure to take him out after he wakes, eats, drinks or plays.
Remember to reward him for being right - say "good boy", or occasionally even hand him a tidbit, for going in the right place.  Dogs repeat behavior that works for them!
