Dog urine contains ammonia and some organic particles that can encourage bacterial growth, resulting in a smelly carpet. Dogs smell their own urine and go again in the same spot. Cleaning dog urine on linoleum is easy, but cleaning urine on a carpet can be difficult. In learning how to clean dog wee, the first step is to absorb as much of the urine as possible before it dries. This reduces bacteria and odor.
Removing the rest requires a wet and dry vacuum. It is also possible to brush cleaner and odor remover into the carpet, but a wet vacuum is best. Scents only mask the urine and do not remove it. An organic solution is to use hydrogen peroxide and baking soda. Both kill bacteria while being nontoxic. After the area is scrubbed, it should be vacuumed to remove the moisture.
