Having a dog with issues is not impossible and can but work out really well, BUT I guess the thing is it can take a lot of time and money and love to get things working, oh yes did I forget to mention the endless patience when you work sooooo hard and you think you have had a breakthrough and then your dog does something like snarl at a child who walks by and you feel like you are back to square one again!
Like others have said some people can do this and some can not. Its not a critism, it can be soul destroying at times so I do understand why some people choose to walk away from a dog if they are struggling. But I guess a dog like Finn who has alredy been to different homes dosn't need another place that will not work out he needs a forever home, so everone involved will have to be very clear about his new hom and its suitability.
To be very honest with you, sometimes I wish for a laid back happy cocker, I think our experience would have been very different if thats what we had got, but Ben is not like that and I know we will always have to think carefully about how we are with him, but I would not swop him for the world. Spending so much time working with him and seeing him progress has built the most amazing bond and he is my world
I guess only you know what you want from a dog. A dog like Finn will probably not be an easy going family dog for a very long time and who could blame you if thats what you want - given the choice wouldn't we all want that?
but you know if you have the time and energy to invest in Finn, and being completely mercenery the money. We have spent quite a bit on 1-1 training, behaviourists etc and consider it well spent, but not everyone has that option or wants to do that.
Good luck with whatever you decide. Don't give up if he is what you really want, but do go into this with your eyes open and understand the work involved.

forgot to add - Finn is scrummy and I wish he could come here....but two boys with issues may just be a recipe for disaster
