Rechargeable In-Ground Fence™ Add-A-Dog® Collar (for SDF-100A)

This collar works great to keep our dogs on our property and away from the chickens. The customer service is the best part though. They genuinely want you to be happy with their products. The one thing i learned is these collars last 3-5 years. So be prepared to replace ‘em every now and then. Still worth it.

Charges quickly and I like the smaller format vs the old "box" style.

Much lighter weight and no more 9 V batteries!
