You do, at a shelter.
You usually do pay for a dog you adopt from a shelter. It's cheaper ofc. I paid 200, which covered his shots and vet bills that the shelter initially paid.
Depends on the country. In here they are all free (Eastern EU)
In the US you pay for dogs. Cats are free. No one likes cats; they kill birds. Dogs only injure hoomans.
