Kit includes all the parts and tools you need to assemble the working model. All you need is a little time, batteries and some vegetable oil!

The manual gives clear, step-by-step instructions to guide you through the build process. Plus, the on/off controller also has a built-in sound chip that reproduces the noise of an engine starting!
Electronic Watchdog Barking Security Device
Now you can have all the advantages of a 24 hours-a-day, 7 days-a-week watch dog without the hassles of caring and feeding!

Just like man's best friend, our electronic version emits fiercely realistic barks whenever anyone approaches. When an intruder is 15 ft. away, it barks intermittently and then barks louder and more frequently if the intruder draws closer. But unlike a real dog, it "sees" through doors and walls up to 25 ft. away with its remarkable radar. You can adjust the distance and volume to your exact needs. And it has four versatile modes.

For security, set it on barking or a combination of barking and 20 sec. siren. For other times, set it on the pleasant rainforest sound continuously or set it on the rainforest chime to announce invited guests. Use it inside near the door or outside under cover. Features high-impact plastic case.
