This is the best. I had tried hemp chews, chamomile and lavender ointment, and thunder vest. And at times all three for my dogs anxiety during storms and any loud noise. Nothing worked. Got this and it calmed him almost immediately and actually calmed him so much he just fell asleep. Glad I ordered two. One for upstairs and down. It’s very cute and soft. Great product with a great price. It’s holding up good so far. Only had for a couple of weeks. Hope it holds up for awhile. As he is not a chewer.

Great product. So cute

So pleased. Helped my 11 week puppy sleep in his bed without crying. Would like smaller ones for Yorkies.

Its amazing

My dog calms down when I put her plush toy near her; when I hear the sound of its heartbeat, I know she's very still.

Dogs can open zipper and pull out all the stuffing easily

Not great for a chewer. My 15 week puppy unzipped it and pulled all of the stuffing out. The stuffing is just loose once you unzip it, there isnt a cloth pocket for the battery pack. She also ate the rectangle hand hold part of the zipper. Really sad this didn't work out. I do feel like it helped her settle a little but just wasn't safe for her. Other than that, it appeared as pictured and worked properly. Also worth noting, the heart beat is LOUD when you put batteries in. I don't know if it calms over time but it was kind of intense.

Zipper is a problem

The first set we received the zipper separated. They were quickly replaced. The zipper tab is very large and our puppy is able to pull it down and pull out all the stuffing. Otherwise it worked to help comfort her until she found the zipper.
