Dogs are truly man’s best friends – we know that from experience – but tragically, humans don’t always return that favor.

That’s why it’s always so heartwarming when people redeem our species by rescuing abused and/or shelter dogs and giving those sweet canines a second chance at life and love. These photos of seven dogs before and after their adoptions make it clear how much of a difference puppy love makes. Prepare to have your heart warmed, and meet:

1. Winston

   Buzzfeed

   Winston was originally abandoned in a backyard, but like all the dogs on this list, now he has his forever home!

2. Thistle

   Buzzfeed

   Abuse meant Thistle lost a leg, but as this picture makes clear, she kept her loving heart!

3. Sweet Pea

   The Dodo

   This pup finally has a home as sweet as her name.

4. Kringle

   Buzzfeed

   Kringle had to overcome having a choke collar literally embedded in his skin. Now, he’s happier and stronger than ever.

5. Filly

   Buzzfeed

   It’s amazing how love helps to return meat to the bones, especially in Filly’s case!

6. Elsa

   Buzzfeed

   Elsa overcame being both abandoned and tied up without food, but you’d never know it from looking at her now.

7. Dexter

   The Dodo

   Dexter had to gain over 45 pounds to get back to playing weight, but it’s the return of his smile that really warms our hearts.
