She used to cry every night in her crate. Now she snuggles the sloth and falls asleep.
Thunderstorms were a nightmare. The heartbeat really seems to settle him down.
So soft and cute. He carries it around the house like it's his best friend.
Tracked shipping on every order. Most orders arrive in 5–21 days.
Turn on the heartbeat device and slip it into the sloth's hidden pocket. The gentle, steady rhythm feels like a warm companion lying next to your dog, which helps him relax when he's home alone, scared of storms, or settling into a new crate.
Everything your pup needs for cozier, calmer days:

The door closes, and he waits by it, whining through storms, restless in his crate at night.
The Muffly™ Heartbeat Sloth gives him a soft, steady heartbeat to curl up with. He settles down, snuggles in and finally relaxes, even when you're not there.
Yes. The heartbeat device sits inside a secure hook-and-loop pocket, so your dog can cuddle the sloth without reaching it. As with any plush toy, supervise your dog at first, and don't leave it with heavy chewers who may tear it apart.
Many dogs find a soft, steady heartbeat comforting because it reminds them of snuggling with their littermates. It's especially helpful at bedtime, in the crate, during storms or when they're home alone. Every dog is different, and some need a few nights to get used to it.
Just press the button and it runs batteries. Turn it off when your dog doesn't need it to make the batteries last longer.
Yes. Take the heartbeat device out of the pocket first, then wash the sloth following the care label and let it air dry.

My dog Gus used to always whine when I walked out the door for work because he was left alone; I almost adopted another dog so he wouldn't feel lonely, but this stuffed toy solved everything. Now I never hear him whine when I leave, which makes me feel very calm and happy.
