We use these on our 1 year old labs to let them know they need to go outside. Apparently it took about a week and a half to fully teach them what it's used for. We first attached it to a board but it didn't work (because our young labs love to chew). Then we attached the old baking sheet and our problem was solved. We have a doorbell in my home office, one upstairs in the nursery, and one in the basement.
