Gorgeous Charlie looking for a new home

I got Charlie a few months ago off someone that wasnt looking after him properly. Since then he has come on so much.he us house trained and doesn't chew in the house.he is coming along with his training now and will sit give paw and when off the lead he doesn't go far and has great recall and he also loves the water and loves car rides too.hes great with other dogs he knows.can bark at new dogs if out but has never gone for one but can be reactive to things and requires somebody that is used to working with a GSD/Large breed, he needs training to socialise and bring on confidence.he also needs more lead training as can still pull on the lead but if he wears a hati he is lots better just needs more time.i did really want to keep him but I'm going to be losing my home soon so he needs to find a new home asap.he hasn't been neutered yet but is up to date with worming flea treatment and is micro chipped. He is also one year old
