First for me too. Good for them. I know some people are critical of importing foreign dogs, but they need rescuing too, and the locals don't want them! It sounds like they are fully prepared for import and have to be fit to travel . The charity deserves support, they are very dependent on the kindness of their vet abroad, and the price to transport them. My mongrel came by white van, very happy. My costs were £250 for the van man , £150 to the charity, and a donation for the vet.
A neglected hairy spaniel is going to be a mess.
