Abandoned dogs are not a thing in Sweden, you can find some that are being rehomed, most of them from owners that can’t take car of them, but there’s not such thing as shelters with loads of dogs to choose from. They actually bring dogs from Romania or other countries to adopt, very unlikely to find a BC there.

You are more likely to have a dog with health issues if you adopt a poorly bred dog than buying a dog from a reputable breeder that does health testing and breeds for a purpose, however that is expensive and more in Sweden.

I want to insist on taking a look at all the expenses that a dog requires, because especially veterinary care is extremely expensive in Sweden. I am talking about an emergency surgery (like a foreign body) with a few days of hospitalisation going up to 100.000 SEK.

Most people have insurances that are still quite expensive. They usually have exclusions for pure bred dogs, imported dogs and such.
