Dog/Pet doorbell

Have you considered making a doorbell for pets? That way my dog can press the doorbell (inside or outside) so she can go potty or come in and I will be notified. If I’m not home but someone else is, I can let them know to let the dog out, or if I’m in a different part of the house, I would be notified that she needs to go outside.It would have to be a totally different ring sound and a different notification on the app. I’ve seen ones that you can use velcro or something sticky to adhere the pet doorbell to the floor or door, but haven’t seen one that will notifiy you on your phone. Thanks for considering
