Your dog needs strong, consistant leadership. All the problems you are mentioning stem from, dare I say it, weak leadership. He seems to have been moved from pillar to post with no consistancy.

You need to set up a structured routine for him which includes exercise, discipline and affection - in that order.

Below is text I have copied and pasted from a previous post who had similar behavioural problems.

Hi. This sounds a bit harsh but usually a dogs behaviour is (a) because they have been poorly socialised (b) because the human is not stepping up to the plate as pack leader.

Without meaning to sound overly critical, I would say that your dog is behaving like this because it is lacking a leader, hence there are so many problems you describe. There always has to be a pack leader, if the human does not fulfil this role then a dog in the pack will take this position. The survival of the pack is paramount to a dog and therefore will always have a leader.

When a dog is put in this position, most dogs being followers cannot handle this responsibility. This, I believe manifests itself in many ways, namely, seperation anxiety, dog and people aggression issues (feel it is their job to protect), incesent barking and to be honest most negative behaviours.

Do you do any of the following?

* When you return home allow your dog to either jump or demand attention and then give him affection straight away?
* Does your dog jump on the furniture without being asked?
* Does your dog walk in front of you on a walk?
* Does your dog walk through a door way before you?

These are all examples of a dog (in his eyes) being the pack leader. You need to ask yourself, are you pack leader or dog lover?

I made all of these mistakes for many months when I got my first 2 rescue's, so please don't think I am being to critical.
