The Smart Dog HT-023 Dog Fence system is the lowest priced system on the market. In this review of this dog containment system, DogFenceDIY.com undertakes a comprehensive review of the system.
The Smart Dog system is a generic, similar in features and operation to the entry level Innotek SD-2000. While the features are similar, it is however much less usable due to poor build quality or the system. The wire and flags included with the system are comical, the unit is plagued by reliability problems, and after sales support is non-exsistant.
