Miniature horse, Sammy and Golden Retriever, Molly have become firm friends.
An unlikely couple, Molly has been nursing the ailing horse back to health. Sammy was nothing but "skin and bones and scared" when he was discovered roaming the streets of South Carolina.
Darlene Kindle of the Carolina Equine Rescue and Assistance in Wingate, North Carolina posted a video of their friendship on Facebook, and it's gone viral.
"Molly truly has an exceptional sense of knowing when one of the animals doesn't feel good or sad," said Kindle. "So she very gently introduces herself. This is her job and she is very good at it."
