Loving home

I need to rehome my 6year old male fixed asap. I can no longer care for him as I lost my job back in June and things are not getting better . He listens good love to be close by . He has lived with a 5lb dog for the past two years with no problems but I'm not sure how he will do with any other dogs . It breaks my heart to have to do this . And I've contacted many shelters but they are all full. I have no other choices left . And it's not fair for him to have to suffer so I'm hoping someone here can take him give him what he needs
