There’s something so heartbreaking about an animal in need — especially one that has been mistreated by humans in the past.

The fact that they have the strength to recover — and that many can learn to love again and become happy pets — should give us all hope that no animal is too far gone.

These amazing dogs were once destined for painful deaths or lonely lives, but they’ve all found their fur-ever homes with humans who love them.

And the transformations they’ve undergone — both behaviorally and physically — are a testament to the power of love and affection.
