Review on Smart Doggie Doorbell by Pebble - Set of 2 by Sara Hunter

This is a great system for dogs. My dog (4 1/2 months old) learned it in less than a day. They let you know when they want to get off, but the best part is they can let you know when they want to get on. I constantly see dogs standing outside the back door waiting for someone to see them or barking. Waited at the door for 15 minutes for someone to answer. Thats much better. We placed the bell speaker in the middle of the house and it can be heard well throughout the house - even on other floors. The bell switch part is very easy to remove when you need silence. This is the only downside - sometimes they might ring to get your attention. You know you'll show up next to the door. When my dog is outside and wants me to go outside and play, she also rings the bell and walks away from the door to let me know she wants me to go outside too. I also turn off the doorbell switch if it's late at night or she's not allowed outside for some reason. All in all, I highly recommend this.
