The inactivation process for positive samples with BPL (to keep the dogs safe) involves a number of procedures that the negative samples do not undergo. Rather than detecting the presence of COVID, perhaps the dogs are detecting the presence of samples kept at 4C (in positive samples) vs the negative samples that were not, or perhaps they are detecting the sodium bicarbonate added to the positive samples that were not added to the negative samples. Perhaps the dogs are detecting the positive samples for having then been heated to 37C when the negative samples were not. THE CRUX OF THE STUDY relies on whether a dog determines whether a particular sample is positive or negative. The paper describes quite well how the dogs were trained, but is shockingly unclear as to how it determines whether a sample is positive or not during the actual randomized control trial.
