works, must be plugged in
I have a dog who has become anxious over the past few months.  I am guessing that anxious is the right word.  He wants to be near someone all the time.  Honestly it is annoying.  Started with him pacing back and forth outside our bedroom at night, and then he would cry.  Thinking he needed to go out, we would get up and bring him out.  Back in, 10 minutes later same thing.  We put up gates to keep him away from our door, and he pushed those out of the way to get to our door.  Finally, desperate to get some sleep, we let him stay in the room.  He is noisy, it is horrible!  He does this lip smacking thing, sometimes ending with throwing up.  He gets up, walks across the room and then flops, loudly, on the other end.  20 minute later he is back to his previous spot.  One night we got the idea to turn on the window AC.  We usually do not run it at night, but just put it on fan for the noise.  Either he was quieter or we just didn't hear him as much.  Realizing we live in New England, and running the window AC, or even having it in your winter, is crazy come fall, I bought this.  One of the fan sounds is like our AC.  Still hear the loud stuff, but now can get a solid 45-60 minutes sometimes, before he wakes us up.<br /><br />This one has a volume knob.  Many newer units have a volume up or down button, so if you don't like any of the 8, 10, 12 set volumes, you are out of luck.  This does run off a USB C cord, and must be plugged in.  I have a USB outlet next to by bed, so can leave that plugged in without any problem.  Sits on my night stand where I can reach over, and flip it on when needed.  If he is strangely quiet, as he has been a night or two since he started this, we don't have to turn it on, but when he starts, especially with the mouth noises, on it goes.<br /><br />Works for us now, also found then when my spouse and I are working in the house together, I will sometimes flip it on.  I usually can not hear what she is saying, but can hear her talking, which distracts me.  Perfect for that purpose also.
