If you’re serious about your pet’s health, the PetPace V3.0 is in a category entirely of its own. Launched in September 2025, it’s the world’s first AI smart collar to include 24/7 free global access to licensed veterinary telehealth and telemedicine — meaning you can video call a vet any time, day or night, with your pet’s live health data already on their screen. Designed by veterinarians and backed by over a decade of clinical research, it tracks an astonishing range of vitals every 2 minutes with medical-grade accuracy. Reviewers consistently rate it at 4.8 out of 5 stars, calling it “an invaluable investment” and “like having a vet in your pocket.”
What we love
✅ Heart rate, HRV, temperature and respiration tracked every 2 minutes
✅ AI-driven pain scoring — clinically validated and unique to PetPace
✅ Epilepsy episode monitoring — a world first, currently in beta
✅ 24/7 free access to licensed vets via live chat or video
✅ Real-time data sharing directly with your own vet
✅ Apple Watch compatibility for instant wrist alerts
✅ Enhanced GPS tracking included
What customers flagged
❌ A subscription is required to access any health data — combined cost of collar plus plan is among the highest in the category
❌ Initial app pairing setup described as finicky by multiple reviewers
❌ Collar bulk can be an issue for smaller or lighter dogs, noted on Hepper and Dogster
❌ GPS is included but not considered as precise as dedicated trackers like Tractive for real-time location updates
Pricing: Collar from $119 (or free on a 2–3 year plan). Monthly plans from $12/month. Best for senior pets, pets with chronic conditions, post-surgery recovery, or any pet parent who wants clinical-grade peace of mind.
The Fi Series 3+ is the all-round champion for everyday pet parents who want GPS tracking and activity monitoring without the faff of charging every few days. In real-world testing, it delivers 6 to 8 weeks between charges with regular daily walks, and up to 3 months in standby mode. It achieves this by switching to WiFi when your dog is home and flipping to cellular when they venture out. The stainless steel collar is IP68 waterproof, 33% stronger than its predecessor, and the integrated design means the tracker literally cannot fall off.
What we love
✅ Up to 3-month battery — the best in class by a wide margin
✅ Real-time GPS with LTE-M connectivity
✅ IP68 fully waterproof for complete submersion
✅ Integrated design — tracker cannot fall off or get lost
✅ Activity tracking, sleep monitoring and step counting
✅ Instant escape alerts to your phone
What customers flagged
❌ Not suitable for dogs under 11.5 lbs — smaller breeds are excluded
❌ Occasional GPS delay during WiFi-to-cellular transitions noted by multiple reviewers
❌ Annual plans only — no monthly payment option available
❌ Tracker adapter required to use on a different collar, sold separately
Pricing: $149 for the collar + $99/year. Best for dog owners who want reliable GPS and activity tracking without frequent charging.
The Tractive DOG 6 has the best GPS accuracy in the entire category — and at $49.99 with plans from $5/month, it’s the most affordable entry point by a wide margin. A major April 2026 update added AI health summaries, scratch monitoring for allergy detection, and a new health dashboard — making it quietly one of the most well-rounded devices at this price point.
What we love
✅ 2–3 second live GPS — fastest real-time tracking in the category
✅ GPS accuracy rated 9.5/10 in independent testing
✅ AI health summaries and scratch monitoring added in 2026
✅ International coverage across 150+ countries
✅ Clip-on design works with any existing collar
✅ Lowest 3-year total cost of ownership in the category
What customers flagged
❌ Battery only 5–7 days standard, as low as 2 days with live tracking — weekly charging required
❌ Physically bulkier than the Fi, feeling cumbersome on smaller breeds per reviewers
❌ App doesn’t distinguish between walks and car rides, skewing activity data
❌ Health features still entry-level compared to clinical options like PetPace
Pricing: $49.99 device + from $5/month. Best for budget-conscious pet parents, travellers, and owners who want the most accurate live GPS at the lowest cost.
The Halo Collar 4 is the only smart collar that combines GPS tracking with a customisable virtual fence training system. Set boundaries anywhere — home, park, holiday rental — and Halo uses GPS, audio cues and vibration to train your dog to respect them. It’s a wireless invisible fence that travels wherever you do.
What we love
✅ Only collar combining GPS tracking with virtual fence training
✅ Customisable virtual boundaries that travel anywhere with you
✅ Humane audio and vibration correction — no shock
✅ Real-time GPS tracking and live location updates
✅ Activity and health monitoring included
What customers flagged
❌ Battery life approximately 30 hours — daily charging is non-negotiable per reviewers
❌ $799 upfront — the steepest entry price in this roundup
❌ Significant training learning curve — requires time investment in the guided programme
❌ Physically bulky compared to Fi and Tractive, noted by multiple reviewers
Pricing: $799 upfront, first year subscription included. Best for dogs who need containment training alongside tracking.
Camicoo is a Dutch smart collar doing something genuinely unique — it’s the only collar on the market combining continuous health monitoring with intelligent bark detection, humanely. No shock, no spray, just smart vibration-based correction alongside temperature, activity and sleep tracking in a single device. A brilliant option for apartment dwellers or anyone whose neighbours are beginning to look less friendly.
What we love
✅ Only collar combining health monitoring with bark control
✅ Humane vibration-based correction — no shock or spray
✅ Temperature, activity and sleep tracking included
✅ Free personalised dog wellbeing check based on breed, age and behaviour
What customers flagged
❌ As a newer brand, long-term review data is more limited than established competitors
❌ Health monitoring is wellness-level, not clinical — not a substitute for PetPace-grade sensors
❌ Bark detection can occasionally misfire in noisy environments per some reviewers
Pricing: From approximately $150. Best for dogs who bark excessively, apartment dwellers, and owners who want a humane solution that doubles as a wellness tracker.
