Puppy aged 10 months/has she forgotten her training ?

We need help with Florrie, she is approaching 10 months old at the end of this month, and she has gone so down hill in her training, house training out of the window she goes where she pleases.
She is destroying everything and anything, she has chewed the skirting boards up the stairs destroyed her basket, bowl everything.
She is ok out on walks which is a bonus but its like a nightmare in the house, she chews, bites people, goes nuts when people come in, she barks the house down, she has started fouling everywhere, its getting out of hand please help, we dont know why she seems to have gone backwards and we dont know how to 'resolve' the issues

What do you, and your family, do when she displays unacceptable behaviour? What general training strategies are you employing with her?

You have posted several times in the Behaviour section regarding her 'problem' behaviour, and you have received good advice from members. Have you read back through these posts? Have you, and are you still, implementing any of this advice? If so, what?

well we are taking all the advice given, and we consulted the vet just incase it was something medical because she was a little wild before, just a puppy, but over the past 2 or 3 months her behaviour has worsened. The vet said there is a possibility, it could be her hormones and a dominance thing with the lunging at visitors and people, and the other pets and when out on 'walkies' tugging like a steam train whereas before she would walk by your side, not sure whether it is hormone and dominance related but just what we were told

So, exactly what strategies/training are you employing to overcome:
barking?
biting?
chewing?
lunging?
pulling?
'going nuts' when visitors arrive?
toileting indoors?

In your first post you say: In your second post you say: Which is it?

It is impossible to give constructive advice without knowing precisely what you are doing in the areas of training and behaviour modification

need more info on how things are luke to help like sb said.

Sounds like you need to set aside more time each day for training and discipline. Do you at the moment do training every day? If not you really ought to start immediately before this gets out of hand.

When visitors arrive is she put on a lead? When she bites or jumps how are you reprimanding her?

Chewing and soiling in the house can be symptoms of separation anxiety - but of course there are other causes, it is difficult to know without knowing the full story so to speak.

Can you go to training classes with her? She sounds like she has dominance issues

thanks for the advice and thoughts everyone, seeminglly things have improved. We have visitors with no bite/barking/lunging. Walkies are nice, the accidents are few and i mean very few. Chewing is being sorted with kongs, chews, frozen rag toys. Generally everything is going good, she seems to have relished having her new playmate, whom keeps her busy playing all day. Things had been let slip with recent events and her training had been sort of one of the many things that slipped away, we are back on track and she is doing very well

I am pleased things have improved Luke just one small thing, training should never stop it is a continuing thing. You need to go on reinforcing the wanted behaviour in a puppy, they can sometimes forget what is required of them and revert to bad ways, also continue to praise wanted behaviour so the puppy knows it is doing the right thing.
