Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive. [2] For this reason it is essential to use multiple different tests to show all adulterants.

But greyhounds without the blue dilution gene are sometimes found. Therefore, a dog that appears to be "blue" may have a black nose and black eyes because it is actually a black dog with the gray gene, not a ...
When a dog has wild-type alleles at all three genes, it will have a yellow coat. When the dog has a loss-of-function allele at MC1R, it will have a yellow coat regardless of the genes it carries on the other two genes. Only a dominant black allele at CBD103 will produce a black coat color in dogs possessing wild-type alleles at MC1R and Agouti. [8]
Example radar chart from the results of the BPH. The individual dog's results are comparable against the breed's average. The results include a score sheet, summary graph, and a subjective summary from the observer. The score sheet describes the behaviour of the dog in each of the 7 (or 8, if chosen) steps.
