How to Get Dog Smell Out of a Couch

The couch your dog sleeps on is one of the biggest odor reservoirs in the house. The smell isn’t just in the fabric — it’s in the padding underneath. Getting it out means reaching both.

What causes it

Dog odor gets into a couch two ways. The fabric adsorbs oils, moisture, and dander from contact. The padding beneath soaks up whatever works through the fabric — and holds it, releasing odor every time someone sits down.

Why it persists

The smell persists because the padding is enclosed and slow to dry. Surface cleaning reaches the fabric but not the cushioning below, so the odor keeps releasing from underneath.

What actually helps

• Vacuum the fabric and crevices
• Wash removable cushion covers
• Treat the padding with a penetrating product
• Dry the piece fully — padding takes a day or more

How to handle it

1. Remove and wash any removable covers
2. Vacuum the fabric surface and between cushions
3. Apply a penetrating or enzymatic treatment to the upholstery
4. Let it work into the padding
5. Dry the couch completely — use airflow if needed
6. Re-check; deep odor may need a second treatment

Common mistakes

• Cleaning the fabric while the padding holds the smell
• Not drying the couch fully
• Forgetting the crevices and under the cushions

Where PawFresh fits
