Yes - got a totally adorable bitch from a local rescue that works closely with a Romanian shelter. It is a very small charity, and the owners regularly visits Romania to decide which dogs would be suitable for rehoming over here, and then when they arrive in the UK they undergo further assessment before being offered for adoption.
There were at least 2 or 3 others that I would have considered adopting. The one I have was actually already house-trained (by the rescue in this country) and we have had absolutely no issues with her at all.
She is rather wary of strangers and can be a little reactive with other dogs, but this is likely to be her breeding as much as anything (she is definitely a shepherd dog cross, and the particular breed is very much a "guarding" rather than a herding breed - they are known for their tremendous loyalty). However, she only needed to meet my DD and DP (who don't live with me) the once and she accepted them completely and now they let themselves into the house in my absence and are greeted rapturously!
She wolfed her food when she first arrived - but now she is getting regular meals she eats at leisure. She is baffled by stairs and the sofa but sleeps all night on her own downstairs without a murmur.
She is good to walk on the lead but still very nervous of trucks and lorries although has quickly got used to passing cars. She is proving pretty easy to train and is totally delightful. She also has no idea what to do with toys despite my other 2 dogs playing with them around her.
I specifically needed a dog that was good with other dogs as I already have 2 - there has been some settling in issues but this was to be expected when introducing a 3rd dog into an established pair. There has been no drama though.
I would totally recommend looking into adopting a Romanian dog - if they have been street dogs or missing pets at least they haven't necessarily been abused the way a lot of the ones that end up in shelters in this country have been. My girl shows no signs of having been ill-treated.
However, choose your UK shelter carefully - some are more thorough than others about vetting the dogs and getting to know them before putting them up for adoption. The one I adopted through has all their rescues work with a behaviourist first to assess them.
