Gen, I sat and cried at your last post about thinking it was Cookie in your bed. How we have all had something awful happen in our lives and when we wake in the morning for just one split second we think everything is ok then for us to remember.
Even from here in England I have been looking at websites of shelters in America. I just so much want for a happy ending to come of this. Somebody, somewhere has him. Even if he did get out of your garden, somebody must have seen him between then and now.
We got a dog from a rescue centre and was told he was just picked up in the street. I searched sites that posted missing dogs to try and find his owner as I believe he was loved once and not just adandoned as he is so loving and obedient so had obviously been trained. I truly hope that he comes home to you. I can't imagine how you are feeling but all I know is how much joy my yorkie has brought to me and I've only had him 2 weeks.
