Dear lord, do not post on mumsnet that you want to rehome a foreign dog. You get the 'WHAT ABOUT OUR OWN THO' brigade out with pitchforks before you can even blink.
I have two romanian rescues. And I'll have a third, and foster too. I won't keep any more dogs than three though, and will only get more when they pass (hopefully it will be of old age).
It's a wonderfully rewarding thing, to adopt an overseas dogs. Many of them suffer terrors that just aren't a thing in British culture. Thousands of dogs are killed in Romania because no one wants them, and they need more space for other stray dogs to come in. In conclusion, they really are much more in need of love and kindness, than in the UK. UK rescues are generally good, ethical places. The same cannot be said for public shelters abroad - do some research of the starvation, injuries, and suffering the dogs in public shelters abroad go through, it is unimaginable in the UK.
All this being said, it is NOT for everyone, and I certainly would not recommend it for everyone, nor would I recommend it for a first time dog owner that has no experience of growing up and taking an active part in the home with dogs. You mention beer gardens? Forget about it. Maybe in 3-5 years. Probably not. You may not even be able to take it for a walk down your own street for the first 4 months, like in the case of our first. The likelihood is, and although there are exceptions, they really are just that, exceptions, you will find yourself with a dog who is seriously anxious ridden, will need some form of rehabilitation, behavourists, and a solid actual interest in animal behaviour, and honestly, a firm interest in working with dogs with challenging behaviours. You will find odd new behaviours popping up for up to 18 months after adoption, all challenges to get through. This being said, if you are adopting one that has already spent a good deal of time in foster in the UK, you will have a bit of an easier ride of it. Mine came direct from Romania, which is a different kettle of fish.
They are very eager to learn, and actually extremely easy to train. They're usually eager to please, but very fearful in some way or another. I was bitten by my first one, it was a redirected fear bite from a stranger, but regardless it's upsetting. She also had gone for us on a small handful of occasions. Oddly though, she's the most affectionate dog I've had. But, we understand we will always need to careful of her.
It's not an easy route, and please don't do it just to potentially send it away when a behaviour that might be too much for you to cope with, crops up. The beer garden comment, along with wanting the dog to come everywhere with you, whilst is a lovely sentiment, is not always suitable for these dogs, and can overwhelm, stress and riddle them with anxiety further to the point it's harmful. You won't really know, until you get it. Such statements tell me, in the kindest possible way, to please research a hell of a lot further.
