How dog urine differs from cat urine
Dog urine is less concentrated than cat urine, so the smell is usually less sharp at first. The trouble is volume. A medium or large dog can release a lot of liquid in one go, and it does not stay on the surface: it runs through the cover, down into the seat foam, and often through to the platform or frame underneath. A stain the size of a hand on the fabric can be a wet patch the size of a dinner plate inside the cushion.
As it dries, the same uric acid crystals form that cause the lingering smell with cats. They reactivate with humidity, which is why a couch that seemed fine in winter can start to smell on the first warm, sticky day.
Fresh accident: what to do in the first ten minutes
- Get the dog off and remove any loose cushion so the urine stops spreading to the deck underneath.
- Blot with thick towels, pressing hard with your weight. Swap towels until they come up nearly dry. Do not rub, as that spreads it outward.
- If the cover unzips, check the insert. Prop a soaked cushion on its side so air reaches both faces.
- Apply an enzyme cleaner made for pet urine, generously enough to reach the depth the urine went, and leave it for the full dwell time.
- Blot again, then let it air-dry with a fan. No heat: a hair dryer or heater can set the odour.
For a small puppy accident caught quickly on a hardy fabric, that is often all it takes.
Old stains and repeat spots
If the stain has dried, or the dog has used the same spot more than once, the urine is almost certainly in the foam and possibly the frame. Surface cleaning at this point mostly makes things look worse: re-wetting dried urine releases the smell and can leave a brown ring as the moisture wicks out to the edge of the old stain. The odour needs to be treated where it actually is, with enough enzyme to reach the full depth, followed by strong extraction to pull the liquid and the broken-down residue back out.
Older dogs with incontinence are a special case. The kindest and most practical approach is a washable, waterproof throw or couch cover between cleans, so accidents never reach the cushion in the first place.
Keeping the couch dog-friendly
A few habits make a big difference: a waterproof-backed throw on the dog's favourite spot, a vet check if an adult dog suddenly starts having accidents, and fabric protection after a professional clean so the next spill can be blotted before it soaks in. Protection will not make a couch urine-proof, but it buys time.
