Your "House-Trained" Dog Is Still Peeing Indoors? It Might Not Be a Toilet Problem At All
Here's a scene I get called about all the time. A grown dog, desexed, been with the family for years, knows full well where the back door is. Then one day someone finds a wet patch on the teenager's bed, or a little sq**rt up the side of the lounge, or a fresh puddle by the front door right after a walk. The owner is baffled — "He KNOWS better than this. Why is he doing it now?"
Here's the thing most people miss. There's a big difference between a toilet accident and a marking. A genuine accident is a full bladder and a dog who couldn't hold on or couldn't get out. Marking is something else entirely. It's small, it's deliberate, and it's placed somewhere that matters — a bed, a doorway, a new bag, the spot where the visitor sat. That's not your dog being naughty. That's your dog making a statement about who owns the place.
When a dog marks indoors, he's claiming territory. And dogs claim territory when they think the job of running the household is theirs to do. In their mind, nobody else has stepped up, so they will. The wee on the bed isn't spite — it's a dog who's carrying a responsibility he was never meant to carry, and it's stressing him out.
So how do we fix it? A few principles to sit with.
First, this is a leadership gap, not a bladder gap. The dog needs to be shown, calmly and consistently, that you run the ship — not him. My house, my ship, my rules. When the dog genuinely defers to you, the need to claim the territory simply falls away.
Second, freedom is earned, not given. A dog who's marking indoors has too much unsupervised run of the house. Shrink his world right back, earn it back room by room as he proves himself, and you remove the opportunity entirely.
Third, correct in the moment or not at all. Rubbing a dog's nose in a puddle you found an hour ago teaches him nothing except that you're unpredictable. We reward for the behaviour we want to see, and we interrupt the behaviour we don't — as it's happening.
Get the leadership right and the marking takes care of itself. Nearly every time.
