Thanks. Remodeling an existing structure.You will need broadband absorption close to the noise source (dogs) and a lot of mass between you and your neighbor. Are you building (new construction) or remodeling? Compressed fiberglass is a fast, excellent sound absorber. Filled concrete block or poured walls are some of your better mass. Any penetrations will let way more sound through than you would first imagine. PM me if you need more detail.
