diesel is now 11 weeks and his potty training is going really well... we just have one problem. he goes to the door sometimes he scratches or sometimes he whines for us to let him out. but other times he will pee right in front of the door... not a lot but just enough to let us know "hey i got to go outside" i dont want to scold him for doing this cause i want him to keep going to the door... how do i get him to stop doing this????
