Sorry for being absent, I haven't been very well again, and I just typed a huge reply but deleter it by accident. What a spanner!
Thank you for all of the replies and suggestions, and the well wishes, they've really cheered me up, and given us one good ideas on how to sort it out. I do have a very positive (well,for us, not my parents) update, more on that in a second.
Mrsjayy and OThe we don't have any photos but I will try to get some asap, it is hilarious, he looks so silly!

who knows thank you, DH has solved it once and for all I think.
Yes, sadly they could bring a dog over, and they could get into the country fairly easily without visas (grrrrrr!). It is a very long way here though, two jumbo jet flights, then another smaller jet flight, then thre might aircraft flights, then a five hour drive along sometimes impassable roads. It would be hell for a poor dog, it makes me furious them even thinking about putting any animal through that.
