Product-selection methodology
Every system is assessed against the same criteria — positioning technology, boundary behavior, coverage, subscription terms, battery and charging, feedback options, dog size limits, weather resistance, support, warranty and three-year cost of ownership. We publish category verdicts such as “best without a subscription” rather than invented decimal scores, and every page states whether we have tested the product.
No product on DogTech currently carries a hands-on tested label. We would rather say that than imply experience we do not have.
New comparisons, product updates and useful dog-technology guides — without the noise.
