Well, we 'stayed' in last night (to avoid the fireworks) and so had ample opportuity in the hall way to practice our 'Stay'.

I am very pleased to announce SHE HAS GOT IT!!! Tried again this morning whilst out walking and although a little slow at first she soon remembered.

I can now leave her at one side of the kitchen and walk into the dining room. If I don't go out of sight I can get all the way back to her without her budging.

Next hurdle is me being able to leave the room, and return whilst she 'stays'.

Thanks for the tips.
