ooh how true is that?? they always seem to grow in stature once they get on the bed, where you thought your dog was 2ft in length he suddenly becomes 6ft with enormous paws hahahaha!!!
bless 'em all the same though.
I have enough trouble with the cat on my bed let alone a dog. Every time i move my feet she attacks them and sometimes her claws go through the duvet as it is a thin one. OUCH OUCH!!!!!!!!!!!!!.
None of our dogs have ever been allowed upstairs, on the beds or on the furniture. Now we're in a bungalow Lottie goes into the bedrooms (not overnight) but couldn't get onto the beds or furniture even if she was allowed to! 
I love that poem, it could have been written for my friend's dog.
Our dogs (Rough Collies) have always had free range of the house once they are properly house trained but they're only allowed on the bed once we are awake and the throw is put on the bed, never during the night while we are sleeping. They learnt early on that if they get on the bed in the night they get booted straight off.
They also know they're allowed on the settees (covered by a throw) if they're not already occupied by humans or if they're invited up for a snuggle, but if they're told no for some reason then no it is.
Crikey, if ours didn't go up and down stairs there would have been an awful lot of places we couldn't have taken them to over the years - carrying a Rough Collie isn't really an option, except in a dire emergency!
Lots of places we go to require the dogs to climb stairs, we've had friends who lived in flats (no lifts) three of our dogs have been PAT Dogs visiting people in care homes, the beach we use is only accessable by a steep set of steps. What we don't allow the dogs to do is rush up or down the stairs, or play on them.
With indoor stairs our Barney knows to wait until the person on the stairs has reached the top or bottom before he follows you up or down.
We've always encouraged our dogs (not as puppies) to learn to use the stairs under careful supervision. You never know when stairs might be your only access to, or escape from somewhere and that's really not a good time to discover your dog doesn't 'do' stairs!
She looks like a sweetie. 
Damson now leaps down the back three steps as it's easied than walking down them. She trots up ok though.
