How to use:
Fitting guide: A collar should fit comfortably but make sure you can pass two fingers between collar and neck. Check carefully under the collar for redness or hair loss caused by an ill-fitting collar. Remember that puppies grow fast and their collars will need adjusting regularly and eventually replacing. Directions for use: Always attach the locking safety clip securely & rotate the barrel to lock position. Ensure a safe and secure connection before use. The clip must be locked when in use to prevent accidental release.
