The way they do it is to have a number of supervised visits, but given the Covid19 restrictions, they can't happen at the moment. Add to that, we are in guarding isolation, so no such visits can take place until, from our point of view, there is a vaccine. We would not take on a new dog until we were protected from catching, and probably dying from, Covid19, as that would be another stressor for the dog, requiring him to be rehomed again (plus some other side effects for us of course, like we'd be dead!)
I think that unless the Trust cannot rehome him elsewhere (in which case we would take him like a shot) then we have to try to forget him.
He does look like our first Irish Wolfhound, Brora, except she was about twice his size
