My dog Mack is 10 months old. He has been doing REALLY good with the housebreaking for quite awhile. It seems these past two weeks or so he will go inside (mostly pee) and won't signal that he has to go outside. Last night he did it in our bedroom when we were getting ready to lay down (and he had just been out an hour or hour and a half previously and didn't drink any water since he had been out last). Tonight he went while I was playing fetch with him in the kitchen. I was just about to throw his toy and he just went without warning (agian he had been out maybe an hour and a half previous and had drank only a small amount of water). I was wondering if these accidents could be because he hasn't been neutered yet (he's going in tomorrow to get neutered). He seemed to be doing really good and then all of a sudden he stopped trying to tell us that he had to go outside. Is it easier to housebreak once they are neutered?
