Time running out

[COG]

Would appreciate if members could have another look at this dog and see if any one recognises him. He is still being fed and watered by us, and is a lovely dog....BUT we re going to the uk on 3/8. Even if someone is willing to foster for a few weeks, we could take responsibility for him again for another couple of months til end of October ?
Really don't want to just abandon him in this heat
