That is disturbing. Why does the university separate women by size

The test was conducted in a large woman's locker room at the university, with the targets being put in certain lockers. Four trained police dogs were used. The dogs were trained to find illicit substances, so that was used for the test instead of food. The OP bags were tested against ordinary supermarket Ziplock bags, not freezer or heat seal bags I think. Of the 32 searches conducted the dogs failed to find the target only 4 times.  I got the impression that this is normal because sometimes the dogs get distracted for various reasons.  Average search times to find the target were 86 seconds in the OP group and 84 seconds in the control (Ziplock) group, which is not that much of a difference. There are a lot of pictures of the dogs in the locker room in the article. I am leaving out a lot
