Akita urine marking on walls: what removes it

Marking on walls and skirting is one of the harder problems to crack — urine runs down vertical surfaces and soaks into plaster, paint, and the gap behind skirting where it sits and intensifies. The only products that permanently eliminate pet odours are enzyme-based cleaners. Everything else — sprays, candles, standard household cleaners — masks the smell temporarily, which is worse than useless because your Akita will sniff it out and go back to the exact same spots. To point you to the right thing: is the urine on painted plaster walls, raw plaster, or gloss-painted skirting? And has this been happening since you moved in, so we're talking weeks of build-up?

Three weeks on painted walls means the urine has had time to work into the paint and potentially reach the plaster underneath — that's why the smell is so strong. Gloss skirting is actually easier to deal with because it's non-porous, but the junction where skirting meets wall is a real problem area for trapping residue. Before I give you a product: is your Akita neutered? And do you know whether a dog lived in this house before you — because if previous dog scent is in the walls, that's almost certainly what triggered his marking in the first place.

That explains everything. He's picking up old dog scent through the paint and remarking over it — an intact male Akita will do this persistently until the underlying odour is fully destroyed, not just covered. The product I'd go with here is Simple Solution Extreme Pet Stain and Odour Remover. It's a professional-strength enzyme formula specifically formulated for urine, and it's available in a one-litre trigger spray which is exactly what you need for vertical surfaces. Spray it generously onto the wall and skirting, let it sit for ten minutes without wiping, and allow it to air dry — the enzymes need dwell time to break down the uric acid crystals. You'll likely need two or three applications on the worst spots given the build-up. One important step: before you treat the walls, do a small patch test on a discreet area of painted plaster, because the enzyme solution is very wet and some matt emulsions can watermark. If the paint is washable or eggshell, you'll have no issue.

For five or six active spots plus retreating them two or three times each, one litre will be tight. Simple Solution Extreme also comes in a five-litre refill container on Amazon UK, which works out considerably cheaper per millilitre and means you won't run short halfway through. I'd get the five-litre if the budget allows — you'll also want some left over for any new incidents while you're working on the marking behaviour. Once the old scent is properly gone, the compulsion to remark those spots usually reduces significantly, though with an unneutered Akita in a new territory it won't stop entirely without other management.

Yes — don't use any bleach-based cleaners or products containing ammonia on the same areas, before or after. Ammonia smells chemically similar to urine to a dog, so it actively attracts him back rather than deterring him. And don't use steam cleaners on the affected wall areas before the enzyme treatment — heat bonds uric acid crystals into surfaces and makes them significantly harder to break down. Enzyme cleaner first, full dwell time, fully dry — then you can follow up with a normal surface clean if needed.
