Halo 3 GPS Dog Collar - M/L Dogs

GREAT CONDITION - the only damage is on the rubber extension piece as shown. Halo keeps your dog safe with virtual fences, advanced real-time GPS tracking and activity monitoring — all managed through the user-friendly Halo app. The Halo Collar strap comes in three sizes that fit dogs who weigh 20lbs+ (9kg+), and have a neck size anywhere from 11 in. to 30.5 in. (28 cm to 77.5 cm). Follow the instructions below to measure your dog's neck, so you can select the appropriate strap size for them. Measuring Instructions Wrap a tape measure around the front of your dog’s neck. Tighten so that you can fit just two fingers between the measuring tape and your dog’s neck. You can also measure your dog's current collar. Determine the strap size by matching up your dog’s neck measurement with the collar sizing chart. If your dog is in between sizes, we recommend getting the larger size since you can trim it down to fit your dog. The strap can be adjusted for best fit once you receive your Halo Collar.
