I have a senior dog with urinary incontinence and was wondering if anyone has any bedding suggestions (based on experience)? I do have her on medication for the incontinence but it's starting to not work as well and as a result her bedding is getting wet. I've been looking at some of the "waterproof" beds and beds made for incontinent dogs but they're fairly expensive so I thought I'd see if anyone on the forums had any experience with them (or some other solution) and could give some advice. TIA!
