These collars have pre-punched, heat-sealed holes to accommodate the receiver posts. Two adjustment points keep the receiver centered on the dog's neck. These collars do not have a D-ring and are not intended for leash-walking.

To determine correct collar size, measure snugly around the middle of the neck, then add an additional 5% for comfort. Lupine does not provide any sales or service for the systems or receivers. However, their Guarantee does include these collars.
