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.

Squeaky toy doesn’t squeak.

I have a Shih Tzu who loved to kill his stuffies. But they need squeakers. The elephant has a defective squeaky. But before I could put it away to return he jumped up and took off with it. Maybe it’ll last longer.
