Dogs in quarantine

Years ago we had a dog, and moving from Africa to Ireland we had to put him 6 months in quarantine. Having been too young to understand what was happening and voicing an opinion makes me look back at that time in sadness. I believe we should have left the dog in Africa because those 6 months in quarantine completely changed him. He got very agressive and destructive until one day he actuay attacked and bit me! Unfortunately my parents couldn't keep him anymore because it was just to dangerous to have him around. I think this all could have been avoided by not putting the poor dog through all that lonelyness in quarantine.
What do you think about situations like these? Would you part yourself from your beloved dog just to keep him away from such a situation? Or is it dependant on which kind of dog it is, can certain dogs cope better with quarantine than others?

By the way, this is a picture of him when he was a puppy, does anyone know what breed it is?

I strongly think that I couldn't leave my dog because of a move, I consider my dog as part of my family! I must admit that I don't know what a quarantine implies, but I would take some info on how to do this without traumatizing my dog, I hope that the experts made some improvements on quarantines nowadays 

As regards the breed, could it be a cross breed between a setter and some other breed?  

I say the same, I consider my cats my kids and my parents already consider themselves as grandparents hehe... But considering how much work they are, and how much patience one needs it makes me think twice about having real kids!
