Tractive vs Fi: which dog GPS tracker is better?

Tractive clips onto the collar you already use. Fi builds the tracker into the collar. Here is how the two systems compare.

Tractive is the more flexible attachment-based system, while Fi Series 3+ is the cleaner integrated-collar system. Tractive publishes up to two weeks of battery for DOG 6; Fi advertises up to three months for Series 3+. Both require paid connectivity for full remote tracking.

Choose Tractive if collar flexibility matters

The removable tracker can move between compatible collars, and the company offers multiple dog models. Tractive also emphasizes international coverage, which matters to owners who travel across borders.

Choose Fi if integrated design matters

Fi’s hardware sits inside the collar assembly. That creates a cleaner profile and supports the company’s long battery-life claim, but it also ties the tracking system more closely to Fi-compatible collar hardware.

Which is cheaper?

There is no permanent winner because promotions and membership terms change. Fi’s support page listed prepaid plans of $99 for six months, $189 for one year and $339 for two years on August 12, 2026. Tractive’s product page displayed one-year plans starting from $9 per month when checked on August 29, 2026. Compare the full term, renewal and device cost on the day you buy.

Our research verdict

Start with Tractive for a versatile tracker that works with an existing collar and emphasizes international coverage. Start with Fi if an integrated collar and the longest published battery ceiling matter more. Local cellular coverage can overturn either recommendation.
