The choice of buying a Purebred Dog or adopting one from a shelter seems like no choice at all. And, after seeing these 20 before and after adoption photos, you too will have no doubt about what your decision should be.

But if you are still having second thoughts, just take a look at the statistics. According to American Society for the Prevention of Cruelty to Animals (ASPCA), 670,000 dogs are euthanized in the United States every year because they never find an owner. So, if you choose to adopt, not only will you have a loyal friend by your side, but you will be a true superhero in every sense of the word.

Now, take a look at these pictures and you'll see what real happiness looks like.
