This smell is a no brainer for a dog

Dogs are known for their incredible sense of smell. They sniff rocks, grass, trees, and the poop of dogs and other animals. Apparently, they get information from whatever it is they are smelling. Some smells are no brainers for them, or so Bosco says. Take the recent migration of neo Nazis, Klu Klux Klan and various other mongrel groups into southern Arizona. Bosco wants it to be known that he is no mongrel hater, being a mongrel of the canine variety himself. However, he made it very clear that he was not happy about these human packs. What, I, asked him, bothers him about these groups? He said it's all about pollution. He said that their malodorousness has the pollutive potential for infecting the air we all breathe. I thought about this and SB 1070. I have to admit his analysis has the smell of truth.
