Fitting the Collar on Your Dog
Do not spray the device or collar with harsh chemicals including but not limited to flea or tick spray. Always ensure that any flea or tick spray that is applied to the dog is completely dry before placing the collar on the dog. Small amounts of harsh chemicals can damage the plastic components and collar laminate.
Before you can put the collar on the dog, you must pair the handheld device and collar (Adding a Dog to the Astro), and acquire satellite signals (Acquiring Satellite Signals).

Tighten the strap so it is snug around the dog's neck.
NOTE: The collar should fit tightly and should not be able to rotate or slide on the dog's neck. The dog must be able to swallow food and water normally. You should observe your dog's behavior to verify the collar is not too tight.
