Remy, a 4-year-old Staffordshire Bull Terrier mix, was found tied outside the Greenville Humane Society in South Carolina with a note, according to a post shared on the organization's Facebook page. "My sister could not take care of her the way she needed to be. She has illnesses I don't believe are fixable. She needs to be put down as soon as possible," the note read, in part. Local news channel WYFF reported that security footage revealed Remy was tied up on Saturday night, but wasn't discovered till the next morning. Illinois Rescue Searching for a Home for 'Sweet' Senior Rescue Dog Who Adores Getting Tucked inGreenville Humane Society Rachel Delport, an employee with the Greenville Humane Society, told WYFF she didn't think the owner had malicious intent when she gave up the canine. "It was someone who truly wanted the best for her, and just didn't know what to do," Delport said. After taking the animal in, Remy was determined to be "suffering from a grade six heart murmur, which is the most severe and can often be felt through the chest wall," the Greenville Humane Society said. "This serious condition will require an echocardiogram, at minimum. Depending on what is found during the procedure, Remy may require surgery or a lifelong medication regimen." The pup was diagnosed with a skin issue related to a poor diet, the organization added.

"We've had more sick and injured animals in our care recently than we have the funds for," the Facebook post said. "We know shelters everywhere are in the same predicament." Delport told WYFF that the shelter had 15 animals abandoned outside their establishment recently, and the issue is one many shelters nationwide are facing. "Finding Remy abandoned and alone wasn't surprising to our staff," the shelter wrote. "Even though animal abandonment is against the law, it's been happening more and more frequently causing strain on shelters everywhere. We immediately brought her inside, gave her food, and began a thorough veterinary evaluation."
