The first thing to do is prevent a recurrence and get the bed back to usable condition. Washable dog beds help the problem when the dog’s own bed or the bed of another dog in the home is the problem spot.If urine has dried on a dog bed and you can’t launder it, a bacterial enzyme odor eliminator can remove the odor. It must soak in deeply and stay active long enough to finish the job. Sometimes that means more than one application.
