It's harder to do in some countries, in the Netherlands there's basically nothing to adopt and there's plenty free puppies to get that were just randomly born.
There are many many sheltered dogs in other countries which could be imported by the Netherlands. A lot of German shelters do that and both of my dogs are/were originally from Romania. In that country they have a huge problem with stray dogs and many end up in killing stations. They even have a shelter with about 6000 dogs in it (Smeura, founded by an Austrian woman) and mostly export them to other countries because Romanians don’t seem to care about dogs.
If anyone wants to adopt a dog from another country I recommend going through local shelters/organizations that already have them imported. There are some sleazy practices going on with people breeding dogs and then selling them as if they were strays. Also you get to meet the dog upfront before making such a big decision.
There are no good dog breeders, or any pet breeders for that matter. In a world where thousands of abandoned pets are put down because there is no room anywhere for them, you have no good justification to purchase a pet from somebody who creates dozens more of them voluntarily to make money.
You were obviously talking about traditional pets, not service animals.
The service animal industry is also largely problematic and exploitative.
Rescue animals can serve as service animals in a large portion of cases anyways, you don't need "purebreds" to work as herding animals, bomb detection animals, anxiety-comfort pets, guide pets for the blind, etc.
I know multiple people who have service/working animals and my spouse and I both work in the pet foster community, so no not uninformed.
