Music can easily affect your mood. Listening to your favorite rock song gets you pumped up for the day, and soothing melodies can help you relax. Sound is important to the canine communication too, and different types of music can affect your dog's behavior. Research shows that classical music played for puppies can calm them down in stressful situations. It's being used by some veterinarians to keep dogs calm in the high-stress environment of the vet's office. You can employ the same theory for your dogs. If a noise, or thunderstorm, or simply being away from home causes your dog to stress, play some relaxing music to ease their nerves. You can also try leaving on DOGTV, as the relaxation programs were specifically designed to relax your dog while you are away.
