This is a specific conversation about Pet stain and odour removal — what actually works — ask about yours and get one honest answer for your exact situation.

Gradual overnight incontinence in an older Westie is really common — the bladder muscles just weaken with age — but it does mean you're probably dealing with multiple set-in stains that have been building up without you noticing. The only products that permanently eliminate pet urine odours are enzyme-based cleaners. Everything else — sprays, steam cleaners, baking soda — masks the smell to human noses but leaves the uric acid crystals intact, which is exactly what draws your dog back to the same patch of carpet. Can you tell me: are the stains spread across one area or dotted around different spots, and do you know roughly how long they've been there?
Mostly in one corner of the bedroom where his bed is. I only noticed this week but they look quite yellow so probably been there a while — maybe weeks?

Yellow staining means the urea has already bonded with the carpet fibres, so you're dealing with properly set-in deposits rather than a fresh accident. That actually narrows things down — you need a high-concentration enzyme formula with a longer dwell time, not a quick-spray product. One more thing before I point you to something specific: has your vet confirmed this is age-related incontinence, or is this the first time you're flagging it? I ask because in Westies, a bladder infection or Cushing's disease can look identical to normal ageing, and it's worth ruling those out.
No vet visit yet — I was going to book one this week. He seems fine in himself, eating well, just this.

Good — definitely get him checked. It may well be straightforward age-related weakening, but it's easy to treat either way once you know. For the carpet, the product I'd recommend is Simple Solution Extreme Pet Stain and Odour Remover. It's a professional-strength enzyme formula specifically designed for set-in stains, and it's widely used for exactly this situation — older dogs with repeat accidents in the same spot. Soak the area thoroughly rather than just spraying the surface, because the urine will have wicked down into the carpet backing and possibly the underlay. Cover it with a damp towel and leave it for at least 10–15 minutes, then blot dry. You may need two applications on the worst patches. Once it's fully dry, the enzymatic odour signal is gone and he should stop targeting that corner.
That makes sense. Should I move his bed while I'm treating it?
inparticular.ai
Yes — move the bed completely out of the room while you treat and while it dries. If he can smell or access the area during the process, he may just reinforce the habit. Once the carpet is fully dry (give it 24 hours if you can), put a washable waterproof mat under his bed going forward. They're easy to sluice off and will protect the carpet underneath as his incontinence continues — which it likely will, whether it's managed medically or not.
Really helpful, thank you. I'll get the Simple Solution and book the vet.

Perfect combination — the cleaner sorts the immediate problem and the vet visit sorts the cause. Simple Solution Extreme is available on Amazon UK if you need it quickly. Good luck with the appointment; at 11 a Westie can still have plenty of good years, and incontinence is one of the more manageable age-related issues.
