4 year old chorkie

We are seeking a new owner for our little chorkie due to a change of circumstance along with believing he could be a much happier dog in the right home (this will be explained) The decision has NOT been taken lightly and it's taken a long time for us to come to terms with what's best for him in the long run. He's affectionate, playful and loves attention! Would be ideal for someone on there own looking for a small dog or with other dogs of similar breed/temperament, although he is used to younger and older children, he would feel much more secure in an adult only household or a household with older children. We have two other dogs of the pug breed which he adores but part of the decision lies on the fact that he would much prefer sole attention or company of similar breeds (he's much more affectionate than the others and likes to play differently sometimes). Also, being a family of six, walking has proven difficult as again, Buddy has a different temperent making it difficult to take all three. Hence why we feel he is missing out on lots of time on walks as well as our other dogs(again, this will be elaborated). He will not be going to just anyone so please don't take offence if we ask a lot of questions and would like to meet up for a staggered move. He is up to date with all his vaccinations(due in August).
