Importing depends on the breed, the purpose of the puppy, and the country - you’d be mad, for example, if you wanted a Goldie to use in shows (like Crufts) to get a puppy with import lines from Eastern Europe or US, because British Goldies are built very different.
Eastern Europe is also not particularly well known for its animal welfare, so personally I would avoid as I wouldn’t want to inadvertently support poor practice. Some ‘kennels’ overseas (usually with studs) are excellent - but you need to thoroughly research them.
I definitely wouldn’t be happy with multiple litters a year. I just got rid of mine a few weeks ago, and I am genuinely exhausted - doing it well is honestly soul destroying, and also impossibly hard to adequately care if your other dogs for the first few weeks. To do it properly more than once a year or so is impossible.
Champdogs is fine. But it’s like the KC - just because someone is on it, doesn’t mean they are good. But it is far more reliable than Pets4Homes, particularly if you want fully health tested parents as it makes it easier to find that information 😊
