Aggression, behaviour, and animal care among pit bulls and other dogs adopted from an animal shelter
Bibliographic record
Abstract
Abstract Pit bull dogs are a focus of concern because of their reputation for aggression toward people and because they may be mistreated by owners who try to promote aggressive behaviour. This study followed 40 pit bulls and 42 similar-sized dogs of other breeds at an animal shelter. Three pit bulls and two dogs of other breeds were euthanised because of aggression toward people at the shelter, and the remaining 77 dogs were re-homed. Of these, one pit bull and ten dogs of other breeds were returned to the shelter because of alleged aggression. For the dogs that were retained for at least two months, owner reports of aggression in various situations (to strangers, to other dogs, etc) were similar for the two groups. Reported care of the two groups was also similar except that pit bulls were more likely to sleep on the owner's bed and more likely to cuddle with the owner. Pit bull adopters were more likely to be under the age of 30, to rent (rather than own) their home, and to be adopting their first dog, perhaps because of a bias against pit bulls among older adopters. The study provided no evidence of greater aggression or poorer care among adopted pit bulls compared to dogs of other breeds.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
