Hi, I have a house trained dog who has just started going toilet indoors. Always in the same spot. He has a dog door that allows him to go in and out as he pleases and we thought the rug he has been using might have a scent on it so had it steam cleaned yet he still did it. Does anyone have any advise about why this has started all of a sudden? He is not very old either (2 years)
