Thanks for the replies
The chewing is when I'm not there, I do tend to put things down while dashing off to do other jobs, so to an extent it's my fault, unfortunatly the conservatory is full of stuff that 'doesn't belong anywhere else' there is still plenty of room for her and she does have chewies and toys there. It's obviously more fun to find different things to play with! I don't know how she got the milk jug, I'm sure I didn't leave it on the floor, I wondered if she found it because of my scent was on the handle (the bit she chewed)
The 'stay' was mainly while I was trying to clear up, and not really moving away, but having a wriggly licky dog in my face every time I bend down slows the job down somewhat, if she'd sit by my side for a few minutes that's all I'd ask for now

.
She doesn't take treats from my hand, she ignores the treat and pushes her head under my hand and against my leg, I've tried popping treats in the side of her mouth so she gets the nice taste, but she drops it and pushes towards me. She'll only eat when I leave her alone with her food dish. She would only eat dried dog food when she came, at least we've got her eating meat.
* Thinking about it - we got some liver for them, would small pieces of cooked liver be OK for treats? she does seem to like it. (a local slaughter/food processing company throws tons of liver away, no-one wants it, digraceful!)
Climbing on the furniture was the ony time I've been firm with her, (apart from saying NO sharply just after she came), mainly because OH was losing patience, and she was jumping up while he was eating, I wasn't 'cross' with her, just firm, she's never petted when she jumps up, (I turn away) only when sat or stood, When she's throwing herself on the floor at my feet I get her to sit up before I pet her (which she's quick to do now when I say 'sit up').
OH isn't an 'animal person', come to think of it, he did shout at her for being 'under his feet', (theres a narrow passage in the houe, he was carrying something and she's got in front of him) I've tried to explain a bit about dog psycology, and we can't blame her for the way she is, he has taken that on board, and he is better with her now, and doesn't raise his voice at her, but he doesn't have much patience, but he doesn't have much to do with them, apart from morning and late night walkies.
He is very good when I ask for help with the animals, so I can't complain at him too much.
I'll keep trying with the treats, liver might be a bit messy, and I'm presuming not too much, but I think I'll try a little.
But she's a real little sweetie, who just wants to please

just seen the new posts,
we by-passed the rescue societies, a friend heard about her and brought her from somewhere, didn't ask whether the owner was aware, just presumed it was legal

.
I might give the crate another try, she didn't seem stressed in there, I just didn't want to have to wash her down again (and her bedding). poo is reasonably firm, but squashed in paws is not pleasant (can we have a smiley for 'yuk')
Popping her on a lead is so obvious- never thought of that

. as it's a nice day she's is tied outside just now.
I don't know what she's like with loud noises, no obvious problem with the gun club which we can hear over the hill, we'll soon find out!
'thundershirt' sounds a strange but understanable idea, might think about that.
Thanks
