OK so Biggles who is now 16 months old, is still pooing in the house. He is dry and will ask every time but will not ask for a poo. Whatever training I do stops him but as soon as I stop the training after weeks of being clear he goes back to pooing again. He is taken out regularly and if he does something I praise him like a nutter but I just don't know how to make him understand to ask to go for a poo???? I have just done a few weeks of tether training where he stayed tethered to me in a morning and after his food in the evening until he had done something outside. This worked for about 2 weeks after and then now he has just done a poo after being taken down 10 minutes before. Any ideas as am feeling a huge failure with this and the ignore mess inside went out of the window this morning unfortunately !! I just don't know how to make him understand. Am going back to the tether from tonight but I HATE tether training as I've done it before with a foster.
