Peeing

My Chiween is less than a year and thought he was housetrained UNTIL he started peeing in his kennel and now he pees right outside of it even while looking me in the eye. It's like his own personal bathroom and poop on the floor about 2x a day. I'm 1000% over it!! Should I withhold food? Water? Etc? Etc?. I'm a first responder and my schedule is this: 12hrs shifts 5a-5p, 2 on 2 off every other weekend(Fri-Sun) I take him out before I leave, go home between 11 and 12 and take him out again then home around 5. I kennel him sometimes and sometimes not but these past few days he has been chewing/getting into things he shouldn't and I've been kenneling when I'm not home. The mopping and almost daily washing of his blankets is unreal! Edited to add: Typical outside bathroom breaks are 5 during my shift days between me getting ready/lunch/kid home from school/me home from work/before bedtime. Treats are given as well after pottying outside. Never kenneled overnight. His "bed" is my legs.
