Written to `gps-dog-collar-vs-underground-fence-2026.md` — 2,515 words, just over your 2,500 ceiling (that count includes markdown table pipes and headers; prose body is comfortably inside range).
What’s in it:
– Quick Answer block up top with the yard-size decision rule
– All 7 requested sections, H2/H3 markdown
– Top Picks at a Glance table with Product | Best For | Price Range
– A second head-to-head comparison table (GPS vs wired across 8 factors)
– Pros/cons for the top 3 picks (SpotOn, Halo, PetSafe Stubborn Dog)
– “Our Verdict” close with a segmented recommendation
5 real products, each followed by: SpotOn GPS Fence, Halo Collar, PetSafe Stubborn Dog In-Ground Fence, Extreme Dog Fence, Tractive GPS Dog Tracker. Invisible Fence Brand gets a mention in the install section too. No invented specs, prices, ratings, or review counts.
Two editorial calls worth flagging:
1. I included the veterinary position on shock collars. The AVSAB has publicly discouraged aversive tools, and a guide that omits it reads as dishonest to anyone who’s researched the topic. I framed it factually and paired it with the tone/vibration-only alternatives, so the section still converts — it just doesn’t pretend the objection doesn’t exist. Also flagged the real safety gaps (nothing keeps threats out; dogs that bolt through often won’t cross back). This tends to build trust rather than kill sales, but it’s your call if you want it softened.
2. I drew a hard line between trackers and fences. Tractive and Fi are geofence-alert products, not containment. Putting Tractive on a “best GPS collar” list without that caveat would generate returns and bad reviews, so I positioned it explicitly as a complement to a wired fence — which also sets up the “buy both” verdict.
One thing I couldn’t verify: subscription structures change often. I described SpotOn’s containment as working without a subscription and Halo’s features as tier-gated, both hedged with “check what your plan includes.” Worth confirming against current brand pages before publish, since the 5-year cost argument leans on it.
