Puppy Comfort — Brown Noise and Heartbeat for Dogs — 3 Hours

Three hours of soft brown noise layered with a slow, steady heartbeat — the comforting rhythm puppies and anxious dogs settle to. Gentle and warm for naps, crate time, or being left alone. Volume tip: play this softly — 50 to 60 dB at your dog's position, never above 70 dB. Dogs hear far more than we do; gentle is more calming and protects their ears.
