Sam's saga is one of a senior surrendered to a shelter, the heartbreak of heartworms, and RADAR's role to seal the deal enabling him to find his forever home. On February 2nd, this eight-year-old Lab mix was surrendered to the Darlington County Humane Society shelter in South Carolina. The reason? Sam had heartworms and his owner couldn't afford the treatment. The shelter noted that this sweet older dog was very well-behaved and affectionate. Fortunately, he secured a foster home placement through the Darlington County Humane Society Rescue.
