Sound Machines designed specifically to help keep dogs calm through your long days away from home (separation anxiety), thunderstorms, noisy neighbors, fireworks, and other unwanted noises. They are also great just for helping them sleep through the night! Many of the Sound Machines are targeted at masking unwanted noise, but others feature calming sounds to help reduce their anxiety. Try a few and see what your four-legged friends respond best to! Dogs love these, but they can work wonders for cats, birds, and other pets as well!
