To assure a proper fit, please follow these steps:

1. Make sure that the battery is not installed in the receiver collar.
2. Start with your pet standing comfortably.
3. Center the contact points underneath your pets neck, touching the skin. If your pet has a long or thick coat, consider using the long contact points to reach through the fur.  These can be purchased by clicking here to contact our Customer Care Center.  Note: It is sometimes necessary to trim the hair around the contact points to make sure that contact is consistent.
4. Check the tightness of the receiver collar by inserting one finger between the end of a contact point and your pets neck. The fit should be snug but not constricting.
5. Allow your pet to wear the collar for several minutes then recheck the fit. Check the fit again as your pet becomes more comfortable with the receiver collar.
6. Trim the collar as follows:
   1. Mark the desired length of the receiver collar with a pen. Allow for growth if your pet is young or grows a thick winter coat.
   2. Remove the receiver collar from your pet and cut off the excess.
   3. If your receiver has a nylon strap, seal the edge of the cut collar by applying a flame along the frayed edge.
