How to stop a dog marking in the house
A dog who lifts a leg on the corner of the new couch is frustrating, and it is tempting to decide what it means. We hold off. Small deposits on vertical surfaces are often marking, but they can also be a toileting gap or a medical issue, and the plan differs for each. This page is for the leg-lifter, the chair-leg specialist and the dog who anoints every bag that comes through the door.

Vet before training
Rule out the body, clean the scent, then supervise.
Before any training we recommend a vet visit, and some signs mean calling promptly: straining with little or no urine, pain, or blood. A dog who suddenly starts leaving urine indoors, or who dribbles rather than squirts, may have something medical going on. Once the vet has weighed in, we clean, not with a regular household spray but with an enzymatic cleaner that breaks the residue down, on every spot, including the ones a blacklight finds.
Then we limit the chances to practise. The dog is either in the room with an adult watching, on a leash held by a person rather than tied to furniture, or in a comfortable crate or pen for short stretches, with water and regular trips outside. If confinement brings distress, we stop and use the tether instead. We watch for the sniff, the sidle and the leg beginning to rise, interrupt with a calm word, walk the dog outside and reward it there.

Triggers and tools
New dogs, new furniture and the belly band question.
Marking often spikes when the household changes. A second dog moves in, a new couch arrives smelling of a warehouse, or a baby's gear fills the hallway. In our experience intact males often mark more than neutered ones, though plenty of neutered dogs and some females do it too, so neutering is a conversation for your vet rather than a training plan. When something new arrives, we go back to full supervision and let the dog investigate it on leash, with a person, first.
A belly band is a wrap that catches urine before it reaches the chair leg. Useful, not training: it protects the furniture while the supervision work happens. If we use one, we check it often, remove it promptly when wet, keep the outdoor breaks regular and ask the vet about redness or irritation. If the marking comes with pacing, hiding or tension between two dogs, we suggest a professional assessment, and A program gets recommended at the consultation, not before, and a smaller one when it is enough for the goal.
Asked and answered
The questions people ask us.
What stops a dog marking in the house?
We start with a vet visit, then clean every spot with an enzymatic product. From there the dog is supervised, tethered to a person or briefly and comfortably confined with water and regular trips outside, so it cannot practise indoors. We interrupt calmly when the leg starts to go up and reward toileting outside.
Why is the dog marking indoors all of a sudden?
Sudden leg-lifting indoors often follows a change: a new dog, new furniture, a visitor's scent or a shift in the household. It can also have a medical cause, which is why we put the vet before the training plan, and straining, pain or blood means calling promptly. Once the dog is cleared, we manage the environment and supervise.
Is a male dog marking territory inside because he is not neutered?
In our experience intact males often mark more, but neutered dogs and females mark too, so neutering alone is not always the whole answer. We leave that decision to you and your vet. The training side is the same either way: supervise, interrupt calmly, redirect and reward outside.
Do belly bands stop a dog from marking?
They keep the furniture dry, which is worth something, but they do not teach the dog anything. We use one only as a bridge alongside supervision, checking it often, removing it promptly when wet and keeping outdoor breaks regular. Any skin redness or irritation is a question for the vet.
