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 ...
Dogs can sense fear. It is believe they can smell the pheromone and perhaps they can even feel it radiating from a being. Some dogs can tell a few minutes before a human is about to have a seizure even before the person knows.When I was a kid growing up I had a Lab mix who loved everyone.hile a human will smell something like spaghetti sauce as one smell, a dog smells each individual ingredient. Unlike humans, dogs can move their nostrils independently, allowing them to know what direction a smell is coming from. A dog can both sniff and breathe. These are two different functions.
