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.
