3 year old male jug needs a new home

Here is gus, who is a 3 year old male jug, he is a much loved family member but due to relationship breakdown and my ill health it isn't fair to him as I can't get him out on walks as much as he needs. He eats anything can be a bit greedy if he is allowed to be, very playful. We've had gus 2 years he was in an male abusive house before us so he can be known to flinch from men, it breaks my heart I can't keep him. He has also started to be very nasty to our older female now she has been sterilised which isn't fair on her. A home where he is the only dog and someone who is an active walker as he loves his walks to give him the attention he craves.
