What we measured
349 high-anxiety dogs
From 571 enrolled, 349 met the analysis threshold of 10+ barking events per day at baseline. Working and herding breeds, median age 1.8 years.
On-collar AI, continuous
Fi smart collars classified barking, scratching, and licking by event count and duration. Minutes per day was the primary metric — captured continuously, not self-reported.
7 weeks · 91% retained
Behavioral signals aggregated weekly across the first seven weeks of crate adoption. 349 → 316 dogs (9.5% attrition), indicating consistent wear.
Seven weeks of decline
Weekly minutes/day declined across all three indicators over the 7-week window. Right panel: total Week 1 → Week 7 reduction.

180 breeds enrolled. The top ten map almost exactly to Impact's core customer: high-energy working and herding breeds.
What this means for your dog
Results are training-dependent. A crate alone doesn't solve anxiety — it gives you the tool to do the work. The decline above happened because owners put in consistent effort over seven weeks.
The crate is the tool. The training is the work. The data shows it pays off.
Paraphrasing Fi's own guidance: improvement takes consistent effort from the owner — it isn't automatic.
About this study
Observational study conducted by Fi using smart-collar behavioral data. The reductions shown describe the high-anxiety analysis cohort (349 dogs with elevated baseline signals), not all dogs or all customers. This is a correlation observed among dogs whose owners use Impact crates — not a demonstration that the crate alone caused the change. Individual results vary; the cohort skewed young (median 1.8 years).
