Indoor Solutions.

Don’t put your pets in dog crates all day, Shields® Indoor Solutions allow your pets to be independent within secure boundaries. You can let them have the run-of-the-house, without running the house..

Indoor Shields® Plus Solution.

Invisible Fence put the “in” in “independence."

With a little help from your dog, your newly upholstered sofa can be redecorated in a fetching paw print motif. To your cat, the kitchen counter looks like an all-you-can-eat buffet. Sometimes pets just can’t help themselves. So an Indoor Shields Plus Solution helps instead — whether you’re protecting your home from your pet, or the other way around. Our Indoor Shields Plus Solution keeps your pet out of trouble — and out of the crate. So he enjoys his freedom. And you enjoy your sofa - without paw prints.

  • How they work.

    How they work.

    Both the Indoor Shields Plus and Micro Shields Indoor Solutions use the same technology; the only difference is the size of the signal field.
    The Indoor Shields Plus Unit and the Micro Shields Indoor Unit broadcast a limited-range digital radio signal in a circular field.
    If you choose, your Indoor Solution can include a discreet, insulated cable for a customized boundary. In that case, the radio signal travels along the cable.
    Over the last 45 years, we’ve found that most pets are quick learners. They’re comfortable and enjoy relaxing in their home — without testing their boundaries.
    That radio signal is picked up by your pet’s custom Computer Collar® Receiver. Should he forget or test his limits, the Computer Collar delivers a warning tone as he approaches the Invisible Boundary area. If necessary, it provides a gentle but effective static correction, so he knows he’s gone too far.
    Our expert trainers use positive reinforcement to teach your pet where he can and can’t go inside your home. That way, your dog or cat understands, and stays within the boundaries you establish.
