I am sure that a lot of people already do this, and call me slow on the mark, but I just thought of this. I have an older dog (she is 17 1/2 years old) and she is very sensitive to humidity. Last night when I got home, the humidity level in the house was very low, and my pup was not comfortable. So I threw a pot of water on the stove and cranked it up and the humidity rose really quickly. I thought that I was brilliant, that is until I saw it already posted on the Internet. Lots of people had MY idea long before I did. At least I was a genius for five minutes – in my head.
