Courtney Todd of Oklahoma Westie Rescue told The Dodo:

"We are so proud of him for saving his dog brother. People often think that rescue dogs are broken, and are scarred for life. Rebel’s act of heroism proves that no matter their previous situation they deserve to have a second chance. Rebel is also a great example that rescue pets are amazing, and such loving creatures full of wonderful surprises."
