Review on Potty Train Dog Door Bell - Daytech Doggie Doorbells for Effective Doggy Potty Training by Sophia Medina

Pros: - Easy to learn for my dog (she is 5 months old and took it in 1 day) - Easy to activate (and only activates if something like Tongue or hand is touching it, which is a nice feature) - Good selection of doorbells - Good, loud volume - Comes with two doorbells (which is handy) Possible improvements: - It would be great if there was an option to mute (or unmute). Muting the volume) would give the ringer at certain times of the day (e.g. at night) - I would also like to see a setting that turns off the ringer for say 30 minutes after ringing once. (so your dog can't keep ringing when he's bored like mine) is the best way to choose a doorbell. It's a bit inconvenient to have to go through each of them. - Ability to add custom doorbell tones. Other than that, I really like the product so far! Since we installed this there have been significantly fewer indoor accidents involving my dog.
