My charming little border collie has taught herself a new trick. She can now open shut doors from the outside using the door handle.
She leans against the door with one paw up for support and uses the other to push the handle down. She hasn't quite realised that it only works from the outside and has tried on several occasions to do it from the inside.
We are now considering getting locks for every interior door, just so we can get some peace and so the cats can eat their food.
