PitPat Activity Monitor
The best overall for UK dogs. Accurate step and rest tracking, genuinely useful drop-in-activity health alerts, and breed-specific goals, all with no subscription. UK company and support. The benchmark dedicated activity monitor.

Felcana Go
The vet-developed monitor, and the strongest pick for cats as well as dogs. Lightweight, waterproof and bite-resistant, with a two-week battery and no monthly fees. Its clinical pedigree shows in the health-focused insights.

Fi Series 3 Smart Collar
A smart collar that pairs strong activity and rest tracking with sleep-pattern alerts and breed comparisons, in a rugged collar with excellent battery life. Health insights need a subscription, but the hardware and data are among the best.
8.3 / 10 -
6PetTechHQComing soon
Invoxia Biotracker
A high-tech health collar that uniquely monitors resting heart rate and breathing rate alongside activity, using onboard AI validated by vets. Genuinely advanced health data, but it is GPS-based with a subscription and a premium price.
8.03 / 10 -
7PetTechHQComing soon
Animo Behaviour & Activity Monitor
From the makers of SureFlap, a behaviour-focused monitor that tracks activity, sleep and notable behaviours like scratching and shaking, alerting to changes. No subscription and a long battery, though it is dog-only and now a slightly older design.
8 / 10 -
8PetTechHQComing soon
Whistle Health
A health-focused smart monitor that tracks licking, scratching, sleep and activity in a polished app, flagging behavioural changes that may signal problems. Excellent insights, though UK cellular support and the subscription are the considerations.
8 / 10 -
9PetTechHQComing soon
PetPace Health Collar
A senior-pet and clinical-focused collar that monitors vital signs, posture and activity, alerting to abnormalities. Aimed at pets with health conditions and vet collaboration. Powerful but niche, with a subscription and premium price.
7.73 / 10 -
10PetTechHQComing soon
Garmin Sport Activity Tracking
Garmin's sporting-dog device pairs rugged tracking with activity data for working and field dogs, with excellent battery and build. Powerful for its niche, but it is a large, training-focused unit rather than an everyday wellness monitor.
7.65 / 10 -
11PetTechHQComing soon
Kippy EVO Activity (with GPS)
Best known for its activity timeline, which clearly maps spikes of effort through the day, useful for training. A GPS-plus-activity device rather than a pure monitor, with a longer battery than most GPS trackers but subscription required.
7.65 / 10 -
12PetTechHQComing soon
PETKIT Fit Activity Tracker
A compact, affordable activity and sleep tracker that clips to the collar and syncs to a tidy app, with no subscription. Good for basic step and rest tracking at a low price, though the health insights are shallower than the leaders.
7.65 / 10 -
13PetTechHQComing soon
Pawfit 2 Activity (with GPS)
A UK GPS-and-activity tracker with steps, calories and active-time monitoring plus a voice-recall feature. The activity side is solid if not the deepest, the subscription is among the cheapest, and the IPX8 build shrugs off muddy walks.
7.5 / 10 -
14PetTechHQComing soon
PetSafe Activity Tracker
A straightforward, affordable activity tracker for everyday step and rest monitoring, from a trusted brand, with no subscription. Fine for basic fitness goals, though it lacks the behavioural depth and polish of the category leaders.
7.4 / 10 -
15PetTechHQComing soon
Tractive Activity (with GPS)
A GPS tracker with useful activity tracking layered on, rather than a deep activity monitor. The activity data is basic next to PitPat or FitBark, but if you want location and fitness in one cheap device with a subscription, it makes sense.
