"Well, we just purchased the item, for Mickie and Ava our Maltese, but so far is doing it's job. I didn't know at first the button on top was to push for "extra" sound when the dog barked too much so I was pushing it, wondered why Mickie ran upstairs! Ava doesn't seem to mind as much, but it does allow them to bark a time or two, then it must go "off" because they shut up!
Mickie has already learned the machine is "bad news" if he sees me pick it up he heads for th hills!
Will let you know if it continutes to do it's job!"
