sos. anyone out there who can give advice. my 6 yr old dog is house trained and goes out regularly to do his business, food and water gets taken away after 6, he sleeps in a large crate and has done so since he was very young but now and again when i get up i find he has peed in it and over his blanket he knows he has done wrong as he wont come out of the crate and though i discinfect the crate, he still does it. what can i do to stop this as i am fed up of constant cleaning and washing his bedding. he goes out late at nite to wee and i make sure he goes, and he goes out early in the morning,
