Our verdict

A solid choice for permanent yard containment if you are prepared to bury boundary wire and want a system that scales to multiple dogs.

Overview

The SportDOG SDF-100C is a rechargeable in-ground fence system with a waterproof collar receiver offering tone, vibrate and static correction levels, sold with 1000 feet of boundary wire and 100 flags covering up to 1 1/3 acres out of the box.

The base kit is expandable to 100 acres with additional SDF-WF wire and flag kits, and to more than one dog with extra collar receivers, so it scales beyond the starting acreage rather than being fixed to one yard size.

  • 1000 ft boundary wire plus 100 flags
  • Covers up to 1 1/3 acres, expandable to 100
  • Rechargeable Li-Ion waterproof collar
  • 2 year manufacturer warranty

Who it's for

Owners wanting a permanent, buried in-ground containment system rather than a portable or GPS-based fence, for one or more dogs on a property up to 1 1/3 acres, or larger with add-on kits. Not a fit for anyone who cannot or does not want to bury wire.

Pros and cons

Pros
  • Escalating tone, vibrate, static correction levels
  • Rechargeable Li-Ion collar, no disposable batteries
  • Expandable to unlimited dogs and up to 100 acres
Cons
  • Requires burying 1000 feet of boundary wire to install
  • Base kit covers only 1 1/3 acres before needing add-on wire kits

Performance notes

The system escalates correction in stages, tone first, then vibration, then static, as the dog approaches the buried boundary wire, and the rechargeable lithium-ion collar avoids the need for disposable batteries common on older in-ground systems.
