Where can you purchase a barking dog burglar alarm?

Walmart.com and Sears.com both sell barking dog burglar alarms. These alarms come with recorded sounds of a barking dog, with some of the products even making the bark more ferocious as the burglar approaches closer.

One example of a barking dog burglar alarm is Wal-Mart's Safety Technology EWD-1 electronic barking dog alarm. With a bark sounding similar to that of a German shepherd, this product protects homes, stores, factories, RVs and any other location that has access to a corresponding outlet. The sound can travel through windows, glass and thick doors, and it deters possible burglars as well as bears.
