We gave up crate training pretty early on but finally we decided we must go back. When we first moved in Ed and Eddy organically realized that the bathroom is the best place for potty accidents, but in the beginning of the year my brother stayed with us for a while and insisted on shutting the bathroom door even when not in use. This trained our boys to pee on our new rug from World Market. It is a damn expensive rug too.
After many accidents and much scrubbing (Vinegar gets pee out of wood btw) the rug has been salvaged, but our dogs are back to being crate dogs at night. We now cover it with a black blanket, this relaxes them more allowing for sleep.
