I come here as a novice gun dog trainer with what I deem to be a well mannered and obedient, yet, very high strung bird dog (2.5yo GSP). She has her issues due to high energy levels but she's a good house dog, obedient in the yard and a machine in the field. All of her training obedience/hunting has been home schooled.
Fast forward to my other dog, a 3yo maltese/shihtzu mix (wife's dog). I despise this dog lately. Like many small dogs he has a lot of obedience issues, doesn't listen, jumps on people when they come in the house, needy lap dog, etc. I never did any training with this dog.
To my problem. He's housetrained, has been since 16 weeks old or so. Lately (the past year probably) he gets up in the middle of the night and pees in the hallway, or on the shower mat, or in my son's room. He hold's it all day (8 hours) while we're at work. We pull the water at 7 or 730, he gets a half mile walk at 10 and then to bed. Probably every other night I find a pee spot the next morning. I'm lost, not even sure how to address this problem. Suggestions, comments, ideas?
