You have the right idea, by having something that allow him to get up off the ground. Just about anything in the way of old blankets, etc. will work as bedding. The suggestion about inexpensive sleeping bags is a good one. I might also suggest something as simple and inexpensive as large cardboard boxes placed around his bed, to keep the wind off him. He might even prefer going inside one of them and using it as a bed -- dogs really love to have a "cave" they can curl up in.
But may I suggest something else, with regard to your quest to find him a home? PLEASE consider contacting a Golden Retriever Rescue organization. This link will take you to a state listing:
http://www.absolutelygolden.com/rescue.htmYou're not limited to just North Carolina; you might consider also contacting a rescue group from a neighboring state. Breed rescue people are extraordinarily dedicated to saving these dogs, and if they have people available who can foster the dogs until a forever home is found, they'll oftentimes also travel a distance to pick up a dog, if you're unable to deliver it. They will NOT surrender a dog to the humane society, so there's no worry of a dog being euthenized. If they accept a dog, they will foster it until a forever home is found that fits just right for Gus. Most even operate "Underground Railroads" where different state rescue groups talk to one another, and volunteers will drive a dog 100 miles, hand it off to another volunteer who drives it another 100 miles, etc. -- until the dog is delivered to its forever home. That's one of the volunteer activities I do. I've transported dogs that started out in Delaware and ended up in Illinois.
Seriously -- please consider contacting them, and telling them about Gus. And let me know what happens. Neglected dogs really pull at my heartstrings, and I would love to know that he finds a good home. Let your neighbors know that they're doing the right thing, to surrender him.
Good luck.
