Diabetes affects our blood vessels and nerves and therefore can affect any part of the body. However, certain parts of our body are affected more than other parts.
I don't think dogwoods have (much?) scent, maybe just lightly floral. The white petally looking things are not actually petals they are bracts, like a poinsettia has. There's something called an English dogwood that is very fragrant, but it isn't a true dogwood and is also known as mock orange. Bradford pears have a smell that this author described as sweaty socks, so if your tree doesn't smell very good that's probably it: http://www.gardenguides.com/106133-dogw ...
Why dogs stink. He smells like a dog, the client says. Being as he is a dog, this doesn't seem to me to be a problem, technically. If, being a dog, he smelled like, say, a camel -- now that would be a problem. Of course, this is not the truly stinky dog. Every dog has a tendency to smell a little strong when wet. If you can love your dog when he's wet, then you really love your dog. Something about being wet, or even just a really humid day, brings out that doggy odor. That's not too bad, though.
