We have 2 young Border Collies. They are not quite 12 months old.
We did all the normal house training things when they were pups, like the News Paper at the door, rewards etc
For a while they were doing the right thing. The boy, Bailey, would even wake us up at night to go outside.
Now, even after being out all day, and taking them out to go to the toilet just before bed, they do not wake us up but rather, go and do 1s & 2s in the kitchen area.
What do we do? We cannot catch them in the act because we are asleep. We cannot leave the Dog Door Open because they will bring mud through the house.
Could someone advise?
