Thanks for the additional information. It is helpful. There are several reasons why this might be happening including a urinary tract infection, house training issue or marking behavior.
Dogs need a cup of water every day for each 8 pounds of body weight. If he is very active, then he might need a little more. So if he is drinking a lot more water than he needs he could have a urinary tract infection or kidney issue that is making it difficult for him to hold his bladder. Common symptoms of a urinary tract infection are frequent urination, dribbling urine, blood in the urine, squatting frequently to urinate, strong odor to the urine, inappropriate urination and straining to urinate as well as an increase in fluid intake.
A dog with a UTI does not always show all the symptoms and typically displays 2 or 3. I believe you need to have your Vet check your dog out so it can get medication for the problem if your dog is displaying 2 or more of the above symptoms..
Other causes for increased thirst and frequent urination include kidney failure, diabetes mellitus, cushing, and liver disease to name a few. You can read about this here:
It could be that he is marking his territory. It is a common issue with male dogs. Unfortunately, you have to be present when the issue is occurring or there is no way to let him know it is unacceptable behavior in the house. Reprimanding him after the fact doesn't teach him anything except to maybe hide where he does it next time. They figure you are mad about finding it, so they hide it better. Obedience training can help with this issue as the dog will see you as the boss and if you are the boss, you can "claim" the house as YOURS and he won't be as inclined to mark. The following site is helpful for teaching you how to train your dog. Be sure and click on the link to the page on obedience at the bottom. and links on subsequent pages leading to detailed instructions.
Training works best if you train at least 30 minutes a day (two 15 minute sessions). I would start making your dog work via the Nothing in life is free program (NILF) can also establish you as the boss. It is outlined below.
And the other would be house training issues. You would need to retrain him the same way you did as a puppy. Crate training would help for both of the last two reasons for overnight. You would not want to have a bed in there as a dog will urinate on their own bed since it will soak up the majority of the urine. It doesn't give him any consequences such as discomfort from having to sit in the urine. Usually if they sit in it a few times, they lean to not eliminate in the crate. It might mean a bath in the morning but is worth eliminating the problem.
The other things you can do are to make sure anywhere that has been urinated on is cleaned with an enzymatic cleaner. Be sure you let the cleaner soak in real good to reach everywhere the urine has soaked down into such as the padding. For old stains I let soak over night if possible. The other thing you can do if the dog has no medical issue, is to take up his water around 5pm so he has ample opportunity to urinate before bedtime. Taking him for a long walk before bedtime aslo helps as he has the opportunity to eliminate and you will know he urinated as well as tiring him out so he may sleep through the night
