i do think the title of the article is a bit over dramatic, but as for the article itself, i red it as being the fact that the dogs nose is used more excessively than a pet dog, and also it is being exposed to a verity of different chemicals and substances that is wouldn’t normally be exposed to.
i see was foxy is saying about them not actual snorting it, but a small is lots of particles off the substance just much much finer and then think how sensitive it is compared to ours.
but i do understand how upset the family must be over peoples reactions and miss interpretations of the article.
