Hi I have a 6 year old yorkie and he has been trained to potty on pee pee pads and has done fine, but since we have moved into our new home he has all of a sudden decided to potty and poo poo

anywhere he chooses. Any thoughts or suggestions? We have moved his potty pads around to where he has been. He was fine the first two weeks in the home but now he is going potty infront of doors, the bathroom and in the hall way landing. I dont know what to do, we are using diapers on him, we tell him no, we place him on his potty pads. Any suggestions would be greatly apreciated as I dont know what to do. If I am not right there with him he is in a kennel as I cant get him to potty on his pads.
