Effect on Other Animals   I noticed in the article that there is no mention of the devices effect on nonhuman animals This is something I was genuinely curious about when reading the article presumably animals such as dogs find the devices sound at least as unpleasant as the young people it is used to disperse Is anyone aware of any research done into this or have any anecdotal evidence of relevance  My family considered buying a Mosquito a few years back to deter loiterers behind their house and had a dog at the time so this is something Ive always wondered about
