The dog peed on the bed, and the mattress smelled of her urine, which was very big. How to get rid of it? Please answer.

Wash it. I had just washed the mattress before our dog died. No matter how rich we are, we cannot always throw it away. I just soaked it in an oversized basin and used a lot of laundry detergent. Then I dragged the dog to the bed and pointed to the urine mark on the bed to scare him into spanking several times. If you don't want to give up, you will definitely be condemned by dog lovers, but then the dog will have a memory.
