If you're worried about Fido and Sport lazing on your fancy furniture while you're busy at the office, Sofa Guard can help. Essentially, the all-new pet alarm is a 4 1/2 foot mat with sensors that you lay out on your prized possessions. As soon as your 4-footer sets a paw on the contraption, a 105 decibel alarm makes sure they hop off with equal vigor. Of course, if it works anything like the heavily-touted Bark Collar (which used to only go off when our office dog would scratch itself), it could end up confusing your dog more than training it.
