If you are interested in adopting a dog, you have to take into consideration that dogs need to be taken care of. Dogs need food and water and they also need an opportunity to get out of the house for some exercise. You will also need to spend time with the dog, playing and interacting with it. To adopt a dog, go to your local animal shelter.
If there are none of the specific types of dogs you want at your local shelter, check out another animal shelter. In some cases, shelters have special adoption events where they have a variety of dogs from different breeds and maybe even from other states.
