Short Post: The WiFi dog fence systems shipping now are two-collar compatible systems. That means you can use this system with two dogs. Each collar on the system can have the correction level independently set.
Hear what our customers are saying about the Dog Fence DIY difference:
I have two hounds who are notoriously bad at confining. They dig under or jump nearly every fence I've tried. At my wits end I purchased the Innotek 4100 Invisible Fence from DIY. I hired two college kids to install the line and hook it up, charged the collar and within two training sessions my Bloodhound was safely contained. What a relief! I purchased a second collar and found that my second hound was just as easy, if not easier to train to the system ... the system works as intended, even under 2 feet of snow! I am extremely happy with this system and if I relocate, it's going with me.
