I keep seeing a product called BarkOff advertised on TV that supposedly stops dogs from barking. It is not the shocker collar type. It's not expensive at all but the sales tactic is what makes me a little suspicious. It's only $10 plus S & H of $7, and then they are presently offering 2 for the price of 1, but the kicker is another $7 S & H charge! Furthermore it can only be ordered by phone with a credit card, but delivery is 3 to 6 weeks!!! Almost sounds like a scam to get credit card numbers.
