The SDF-100A underground dog fence is an excellent system. In my complete review, I showed the most economic version of this fence. That system comes with a 20 gauge, solid core, burial-grade wire. Most pet containment systems will come with 20 gauge wire included. This wire will work fine, but can be damaged with an edger or other yard tools. This can be avoided by burying the wire deep enough to be out of reach of these tools, but it can also be (after a while) susceptible to weather conditions.

I’ve always recommended that if it fits your budget, you should use a thicker gauge wire on these underground systems. The next system I looked at was the SDF-100A w/ 16 gauge wire upgrade. This is the exact same system with the exception of the wire upgrade. It uses a 16 AWG wire. This wire is is a much thicker and stronger than the 20 gauge wire.

    The second upgrade I’d like to talk about is the SDF-100A w/ 14-gauge upgrade. In the event of a wire break, you’ll have the not so pleasant task of trying to find where the break has occurred. You could purchase a wire break locator, but these are only good to detect a complete break, not a partial break.

    14-gauge wire is what I like to call “dog fence wire on steroids” 🙂 This wire is 5 times thicker than the 20 gauge wire that most pet containment systems include in their package. It’s professional strength 14 AWG PE45 steel core corrosion resistant copper clad wire. Tough Stuff! This is for people who like to do it right and do it only once.
