Naughty naughty dog- advice please.

Lulupie

Hi all- in April we had two Dachsunds and a Pitbull x handed over to us (they have joined our resident poodle and Pitbull x staffie). The new Pitbull x is nine years old and is named Keira. She's very dominant and active and I'm not sure how to get her to calm down.

Whenever we have people over she's all over them. She jumps on them and bites and then she humps them. She doesn't listen when you say no, she doesn't listen when you SHOUT no, she keeps going back if you physically pull her away.

How can we put an end to this behaviour? We barely have people over because of this (and it's not just the first few minutes of excitement that she acts like this, it's the ENTIRE visit).

Thanks!!!
