My 13 year old dog, Sakura, has not been crated in over ten years. Lately with her losing bladder control I was debating crating her when I go out. She is destroying my parents hardwood floor. She has pee pads, but is still learning to use them. She uses them occasionally. She still goes outside, but can't hold it overnight most nights. I think it's confusing her, letting her pee on the pads. She knows she is supposed to go outside. I'm wondering how much it would stress her out to start using a crate?
