While it is not likely that bad pet smells will just go away on their own, they can be removed with proper care. If you take steps to address the source of the odor, such as washing clothes with odor-eliminating detergents or using natural remedies like baking soda for dogʼs smell, you can successfully remove pet smells from clothes in many cases.
However, it's important not to ignore the odor for too long, since it may persist if steps are not taken to address it.
