That’s really not a great study, finding “no difference” after only one month really means nothing. Most scientific experiments test the null hypothesis, which means there is no difference between x and y, and most experiments show this, it’s a very common finding, but it means little. We don’t know what type of dogs they used or their methods of testing the environment. Also, we don’t know what type of environment was tested, were windows open most of the time, was a filtering system used in some homes? This was not a closely controlled experiment, so to me it means nothing. My nose and eyes can tell the difference between hypoallergenic dogs and those that aren’t! |
