Is your dog or puppy experiencing separation anxiety or barking when you leave him alone? Does your puppy whimper constantly? Does your wounded or sick dog need comforting? Is your dog generally hyperactive? The heartbeat nursery songs on the Canine Lullabies CD have been used for years to help calm infants and children. It has been shown that this music can also be used to calm dogs and to reduce barking. It is a method that all dog owners should try first to calm their anxious pet before resorting to medications, shock collars or other expensive therapies.
