HOA board orders dog removed after neighborhood attack

I am a Florida member of an HOA.  A neighbor was working in my single family home and let my dog out by accident.  The dog attacked another dog walking by, the owner was bitten whilst separating the dogs. The dog is 9 years old and has never bitten anyone before. The Condo Association Board have instructed me to get rid of the dog because they consider it to be dangerous. The matter has been settled with the owner of the dog. The documents allow dogs and there have been similar incidents with no action being taken. Is the Board acting reasonably?
