How did you approach? Perhaps too firmly? Firm does not mean intimidating.

You have a dog with bad history and it takes time to get things right. Sometimes you will experience the feeling of going one step forward and two step backwards in training, but don't be discouraged, keep being calm and friendly even if you get annoyed sometimes. To get a dog obey you sometimes you need to play by his rules or better said - make him think so
In my experience with the one I foster at the moment when I want him off I come to him as if I want to pet him, completely calm and in a friendly voice I say "off". If it doesn't work straight away I call him "come, let's go" with voice that invites to play and have fun. When he does, I really do have some play time (short) with lots of praising and a treat. I get what I want and he's happy and doesn't feel like he's at loss for losing his spot on the couch.
He's like that with Darrin because Darrin is more rewarding. And that's OK, but you should really have a talk and set things straight in regards to rewarding anything. If he gets rewarded for anything he will start taking advantage slowly for some things, any dog does it in one way or another (although some things are not easily noticable or important to owners). So, no treats for attention barking and no cuddles whenever he wants.
my partner lets him get away with way to much IMHO but he gets full respect from the dog and arrow is very submissive towards him even though if he barks for attention he will get it from darryn, if he wants a treat he will get it from darryn without having to do anything for it!
Aggression towards men and strangers takes a lot of time, lots and lots of work and patience and lots and lots of positive experiences wit many different people/men/kids, preferably with the supervision of professional trainer/behaviourist.
Respect and you shall be respected. Animal is always right.
