Canine behavioural stress is often triggered by their acute hearing of sounds in the environment. The benefits of music in the canine listening environment have been proven in previous studies, showing calm and more balanced behaviour. To further understand the calming effects, Janet Marlow at Pet Acoustics, Asaf Dagan at PetPace and Ron Pia at The Pet Calmer analyse the biometric data of mostly small dog breeds while listening to the species-specific designed music.
