I'm a bit confused.... I've read the op's post several times now and find no suggestion that the dog would be abandoned.
The relationship is breaking down, so why is the partner not willing to share responsiblity (partner keeps dog until suitable accomodation can be found in the UK)?
Yes,I have the same disdain for people who move away and leave their pets behind (personally I believe such people should have a wire brush shoved up a place, where only the most skilled proctologist would find it)
Mary, you KNOW the story of our wee dog,but let's not scare the op off. Does the dog have a passport from the outbound journey? If so How long since it arrived?
there IS intelligent life on Earth, but I'm not staying
