Have you ever walked past a dog who was tied out on a rope who DIDN'T bark at you like a pyscho? Dimes to dollars your neighbor's dog's barking will eventually drive you crazy.
Tying out a dog makes a dog feel extremely vulnerable. Anyone who studies dog behavior would not recommend this. Think about it. You're a pack animal, away from your pack, who's exposed to the world. A predator walks by (another dog, a person, a car, etc.) and the dog senses that this threat can hurt them. At the same time the dog can't run away. Since the dog can't run away to safety, it barks to warn the threat away. That's why tie-outs make dogs NUTS.
You'll have to fence your teeny yard or walk your dog several times a day. Or move back to the country. Or get a cat.
