Initial reports suggested that using television or radio as background noise could assist dogs with separation anxiety by providing auditory continuity and masking external triggers. Research noted that classical music might increase rest, whereas heavy metal could increase barking.

However, subsequent findings indicate that television noise may actually disrupt canine well-being. Due to dogs having hearing up to four times more sensitive than humans, the unpredictable sounds of dialogue and advertisements can cause hypervigilance. This prevents dogs from achieving deep, restorative sleep, leading experts to recommend quiet environments or soft, regular music instead.
