Dog Drinking a Lot of Water and Peeing in the House?

I have 2 Pit breed dogs. One is female and is over 9 years old and the other is a male and he is 4 years old. They both are spayed and neutered. Both have been house trained. We have recently moved to a new house 6 months ago. My 4 year old male Pit has just recently started peeing in front of the back door where he goes outside. He dribbles with pee until he reaches the door and usually has two puddles of pee on the floor. He also starts barking which wakes us up at 4 am during these two episodes.

I am at home during the day so they both get let out and have plenty time to empty their bladders. He is drinking water excessively that we have noticed because the water bowl is completely empty in the am. After he is let out in the AM, he goes straight to the water bowl to drink a lot of water. I plan to take him to vet because I have never had any issues like this before. The only thing different in his routine was that I had taken him to the vet to get bathed about 5 days ago because he weighs 117lbs. He is terrified of water and is a big baby, so it's hard to bath him. Please help with any suggestions. Thank you.
