How we score GPS dog fences and collars
One formula, the same for every device, published in full so you can redo any score yourself.
Last updated November 9, 2026 · prices and plans checked November 9, 2026
The rules
- Where the figures come from. Our scores come from manufacturer data, published prices and the formula on this page.
- The plan counts as much as the collar. Every cost is a 36-month total: device plus the plan it needs, at the cheapest published billing cycle. Promo codes are never counted.
- Each criterion is scored out of 10 on a fixed scale (below), then combined with published weights.
- A missing figure is never guessed. The criterion is left out and the other weights are rescaled. Example: SpotOn does not state a battery life for the Omni Edition, so battery is left out of its score. A criterion that does not apply (yard size for a tracker) is left out the same way.
- No score without a price, or with fewer than 3 known technical criteria (cost and warranty do not count as technical).
- Rankings by use change the weights only, never the figures.
- Humane by design. Static correction never earns points. Collars that hold a boundary with tone and vibration alone score highest on boundary cues.
- No brand pays for a place. Some links are affiliate links: we may earn a commission at no extra cost to you. It never changes our scores.
Criteria, scales and overall weights
| Criterion | Overall weight | How it is scored (value = points out of 10, straight line in between) |
|---|---|---|
| Containment | 20% | Custom shapes and several fences = 10, circle or 8-point polygon = 8.5, one custom fence = 7.5, circle around a radio transmitter = 6, e-fence on a hunting collar = 5, escape alerts only = 2.5, no containment = 1. Minus 1.5 when the brand says the fence needs cellular service to work. |
| 3-year cost | 20% | Device price (sale price when lower) plus 36 months of the plan that unlocks the fence and live tracking, at the cheapest combination of published billing cycles (optional tracking plans included). Ratio to the median of all compared devices ($700): 0.3× = 10, 0.6× = 8.5, 1× = 6.5, 1.5× = 4.5, 2.5× = 2. |
| 3-year cost without optional plans | 0% | Same, but only with the plans you cannot skip: optional tracking plans are left out. Used only by the no-subscription ranking (median $700). |
| Live tracking | 10% | Live cellular tracking = 10, long-range radio handheld = 8, no tracking = 2. |
| Positioning hardware | 10% | Dual-frequency GNSS stated by the maker = 10, otherwise 6. Not scored for a radio-transmitter fence. Accuracy claims in feet are not scored: no two brands publish them the same way. |
| Battery life | 10% | Hours per charge stated by the brand: 12 h = 2, 24 h = 4, 48 h = 6.5, 72 h = 8, 168 h = 9, 720 h = 10. |
| Gentle boundary cues | 10% | Tone and vibration, static optional = 10; tone with static optional, no vibration = 7; cues sent by hand only = 5; automatic boundary that relies on static = 3. Trackers that never cue the dog are not scored here. Static levels never add points. |
| Fits small dogs | 8% | Smallest dog weight the brand states: 5 lb = 10, 10 lb = 8.5, 15 lb = 7, 20 lb = 6, 25 lb = 5, 35 lb = 3. |
| Smallest yard | 7% | Smallest yard the brand supports, in acres: 0.02 ac = 10, 0.33 ac = 7, 0.5 ac = 6, 0.75 ac = 5, 1 ac = 4. |
| Warranty | 5% | 5 years or more = 10, 3 years = 8.5, 2 years = 7, 1 year = 5. |
From criteria to the displayed score
raw score = Σ (criterion score × weight) ÷ Σ (weights of the known criteria) displayed score = 7.4 + 0.4 × (raw score − 4), kept between 7.0 and 9.8, rounded to 0.1
The displayed scale spreads the scores of current models, all serious products, on a readable range without changing their order. Labels: Excellent from 9.0, Very good from 8.5, Good from 8.0, Fair from 0.0. Ties are broken by the raw score, then by the lower 3-year cost.
Weights of the rankings by use
Each ranking re-weights the same criterion scores. A weight of 0 means the criterion does not count for that use.
| Criterion | Overall | GPS collar | Wireless fence | No-subscription | Small-dog |
|---|---|---|---|---|---|
| Containment | 20% | 10% | 20% | 20% | 15% |
| 3-year cost | 20% | 20% | 25% | 0% | 15% |
| 3-year cost without optional plans | 0% | 0% | 0% | 35% | 0% |
| Live tracking | 10% | 25% | 0% | 0% | 0% |
| Positioning hardware | 10% | 10% | 5% | 10% | 5% |
| Battery life | 10% | 15% | 10% | 10% | 5% |
| Gentle boundary cues | 10% | 5% | 15% | 10% | 15% |
| Fits small dogs | 8% | 10% | 10% | 5% | 30% |
| Smallest yard | 7% | 0% | 10% | 5% | 15% |
| Warranty | 5% | 5% | 5% | 5% | 0% |

What the score leaves to you
How the boundary behaves under your own trees, how a collar sits on a deep-chested dog and how patient your dog is with training change from one yard to the next, so they are not in the score. Brand accuracy claims ("within 2 feet", "under 5 feet") are quoted with the brand's name and left out of the math. That is why each review says who the device suits and who should skip it, and why a long return window is worth having.
