We provide you with a separate collar attachment that stay's on your pet's collar. The Whistle 3 will then connect to the attachment.
Whistle 3 comes with an attachment piece to secure the device directly onto your pet’s existing collar or harness (up to 1’’ wide). It's made of super strong rubber and is designed so that you can still use whichever collar you choose.
When you want to remove the device, just push the side pin & rotate. This makes it extra secure when on your pet but super easy to remove when the device needs to be charged.
