Two weeks ago, we adopted a little rescue Lakeland terrier who is approximately 10 yrs old. She is perfect in every way - sweet natured, great with other dogs etc, but isn't house trained. I've read up as much as I can about this. She is taken out at least hourly, rewarded when she does wee or poo outside, but not punished or shouted at if she does it inside. The trouble is, she can be taken out and given ample opportunity to go, but then come in and wee on the rug.
Does anyone have any advice? We adore her and are so happy to give her the forever home she deserves, but are at a bit of a loss here.
