when your pet steps on the mat, she will feel a safe-yet-startling correction. the mat also has a safety timeout, so if your paw-tner keeps her paws on the mat for more than eight seconds, the correction stops. it got my son worse than the monster! i tried this mat’s static shock level and at the maximum level it felt like a real shock to me… so we have it at the lowest setting for the two 7 month old …
