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 flat collar or harness (up to 1’’ wide). The durable snap-in design was created as a semi-permanent solution that locks securely on the collar.  

When you want to remove the device from the collar, 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.

Below is quick video showing you how to attach the Whistle 3 Snap Collar Attachment to your pet's collar:
