I have three elderly dogs, two fifteen and one fourteen, and the loo roll and disinfectant is always at hand! However, I have wooden floors throughout and all of them are capable of getting out of bed - it's just being caught short in the night, not making it out of the open door in time, or I'm not speedy enough letting them out of a closed door. As someone in their sixties with a dodgy bladder, I can sympathise with my old ladies! Pottering around in the garden and sunbathing on the warm drive is now their thing rather than long walks and one needs a run up to get up the steps. They love their [dog] food and, even more, dog treats. I'm really conscious of any smell there might be but not one of them soils their bed.
