To effectively remove dog smell from a sofa, a multi-step approach is often recommended. A common starting point is to thoroughly vacuum the entire sofa, including all crevices and under the cushions, to remove loose hair and dander. If your sofa has removable cushion covers or you use blankets on it, washing these items can significantly reduce odors.
For odors embedded in the fabric, a widely suggested method is to liberally sprinkle baking soda over all surfaces of the sofa. Allow the baking soda to sit for several hours, or even overnight, to absorb the odors before vacuuming it up completely.
If the smell persists, liquid treatments may be necessary. An enzymatic cleaner specifically designed for pet odors is a popular and effective solution. These cleaners contain enzymes that break down the organic proteins in pet dander and saliva that cause the smell. Always follow the product's instructions and test on a small, inconspicuous area first.
Alternatively, you can use a homemade solution. A spray bottle filled with a diluted mixture of white vinegar and water can be used to lightly mist the fabric. The vinegar smell will dissipate as it dries, often taking the dog odor with it. Another similar method involves using inexpensive, high-proof vodka in a spray bottle; the alcohol acts as a deodorizer and evaporates quickly. For a deeper clean, using a carpet or upholstery cleaning machine with an appropriate attachment can help extract odors from deep within the sofa's fibers.
