Sleep like a baby
Bringing a new puppy home can be rough on both of you, but this little heartbeat soother made such a difference. The first few nights my pup was whining constantly, but once I tucked this into his bed he settled down so much faster. The heartbeat sound is realistic and soothing — not annoying or too loud. It’s compact, easy to turn on, and the design is simple and clean. Great for separation anxiety too, not just new puppies. Totally worth it for the peace of mind alone!

Heartbeat machine
Not what I was expecting. Pretty small and you can't really hear it. I was hoping to put it up on a shelf for my dogs when I leave. But, they'll never hear it. I'm sure I can use it for something else. Just not what I was hoping to unfortunately

Great replacement heart for bear toy
Many years ago I bought a Heart to Heart Bear (1980s)--with a heartbeat. After several years the heart stopped working, but I kept the bear--thinking that some day I could fix it. Last Saturday I replaced the original heart with this heartbeat toy and now she works great! The heart is not too loud and the fact that I can start and end it without opening the bear is great. I am going to buy another one as back-up just in case this one stops working. Thank you.
