Chewing and potty training

Question
I have a male 7 month old Boxer pup.  He is currently neutered.  We aslo have a 2 year old puggle female in the house that is potty trained and spayed.  Currently our Boxer still pees and poops in the house and even he pees in his crate sometimes.  He also has been peeing in the bed with my wife still in it and while he is sleeping.  My wife and I have tried everything to get him to stop peeing, like taking him out every hour to limiting the water intake to keeping him on a good schedule.  But we are not perfect too, my wife and I are both in the military and work shifts.  We switch from nights to days every 3 months.  Also i am currently deployed so i am not there to help now.  He aslo chews on the side of our window cils too.  We have alot of toys for him to play with and also he has my other dog to play with.  I don't know what to tell my wife what to do.  I have had 2 boxers before this one and they were are trained by now.  I also thought having a potty trained dog would help the other one learn but i guess not.  HELP!!!  lol  

Answer
There could be a urinary problem, or it is your schedule and he is subconsciously acting up.

The chewing and peeing is usually a cry for attention and nervousness.

Have your vet check him for urinary problems to rule that out and get back with me.
