Separate reported improvement from welfare measures

Primary paper: abstract and methods context checked; detailed critical appraisal pending. This note summarizes the linked publication; it is not a study of Angier K9.
- Study design
- The main study compared three groups of 21 referred pet dogs, including e-collar training and two comparison approaches.
- Reported finding
- Owner-reported improvement did not differ significantly between groups. The e-collar group showed more tension and yawning than the reward-focused group; cortisol findings did not show the same simple group pattern.
- What this does not establish
- A reported improvement, an observed response and a physiological measure answer different questions. The setting and trainer differences matter when interpreting the comparison.
Shared source cohort: DEFRA 2010–2011 training records. The two entries from this project must not be counted as independent samples.
