Border collie needs five star home

With deep regret I'm having to rehome my best friend, hes a Very loving boy however can give a protective bark somtimes but only to knocks at the door and if you show him who it is he just wants cuddles, sox is very active and needs tons of running around, swimming and mental simulation. He can occasionally be boisterous with male dogs so just for the best home for him I'd suggest him being the only male dog( he's friendly its just if he feels the other dog is trying to be boss),he needs somone who will look after him in a five star home and give him enough attention and love etc not just somone who's going to be leaving him alone all day or not taking him out every day because he definitely needs to go out every day. Were only rehoming our boy due to work commitments and moving home this is harder than you think so only enquire if you can genuinely give him the best home possible, preferably people who have owned collies before but its fine if not. Thanks for reading
