I have been meaning to mention this for a few days.
When Rodders wants to come on from the garden he used to stand on his step and bark. It was always difficult to open the door to let him in as he was stood in the way.
He has now learnt to stand with his front feet on the step as he barks. When he sees me approach the door he now takes his feet off the step so that he can hop in the door as quickly as I open it.
What a clever puppy!
