Stunning Red Tri Border Collie x Huntaway 3 yr old Boy

It is with a heavy heart I'm looking for a new forever home for my stunning collie x huntaway, Byron. Byron is a lovely sociable, energetic lad who deserves a home where he can get his exercise needs met. He has a lovely shiny coat and is quite fluffy. Byron is fine with other dogs once he gets to know them, which normally takes minutes at most. He loves people and adores his ball. He is very enthusiastic. He can also chill and is very good in the house. Byron knows many commands such as sit, paw (shake),lie down, turn, stay, and can take a treat gently from the hand. Unfortunately I cannot rehome him anywhere with young children as he is too boisterous. Older kids over 14 may be considered. He is neutered and is only just 3 years old. He is up to date with vaccinations and worming. He has never been tested on livestock but came from working parents so may well learn. I am rehoming because I just can't give him what he needs. I have two other collies and Byron is sometimes bullied by them. He needs more attention and exercise than my other two and I am struggling with the three due to my health. I feel Byron would make an ideal pet for a single person or couple without children who love going for long hikes, or have land that he can run about on. He is quite good on lead but must be able to run about regularly off lead. I will only rehome to stellar homes and will want to interview you on phone or zoom or similar to make sure that you are right for him, and also for you to make sure he is right for you. Also preferably meet him in person before any decision. 

For the rehome, I would like to be able to get updates on how Byron is doing, (and maybe even visit him once in a while, though I know that sometimes can disturb a dog). Also I'd prefer him to keep his name as he knows it well now, unless that's a deal breaker, then I suppose you could choose a similar sounding name!
