A greyhound is a dog that was originally bred for hunting and racing. They sleep often and are known for their speed, moving at 40-45 miles per hour.
Positive: Dreaming of a greyhound could represent swiftness or running the race correctly and staying in the area God has called you. A greyhound could represent one who has a heart to quickly do the will of God.
Negative: In a dream, a greyhound could represent anxiety or that one is moving ahead of God and doing their own will.
(1 Corinthians 9:24-25; Philippians 4:6).
