We have an upstairs & downstairs and Dear Dog (9 months) has a doggy door off the kitchen, which he uses 90% of the time. Except when he's upstairs. Overnight. He seems to find it much easier to just poo and pee wherever he sees fit!
What is more annoying is that he recently went to a dog sitter for 2 weeks when we were on holiday, and only had 2 accidents during that time, and they don't have a doggy door! He slept in their bed upstairs and held it in til morning!
Getting slightly annoyed now when I get up in the morning and here we go again. Where am I going wrong?! He knows I am cross with him, and he knows where he should be going! When he does the right thing he gets lots of praise and a biscuit etc.
help! thanks
