Hi,anybody tried out these devices are they any good? i have 2 dogs over the back fence ,they are kept in a small shed with mesh window & door, trouble is when anyone approaches the front of their house they bark postie, deliveryman, this is ok but they forget to stop,this can last 1 hour at a time, owners both work Believe me, approaching them would be a waste of time .Any thoughts?
Don't waste your money on Sonic devices ! We have a JR who barks at postie and delivery men (not for an hour I hasten to add) we tried sonic device and it didn't do a thing. We use a water spray now but if the dogs are in a shed that will not help you !
