So, I was trying to work out what I could teach Evie as a cue so that she can tell me when she needs to go outside. Currently, she quietly walks to the back door and sits and waits to be let out. Only problem is, that if you're not quick enough to notice her missing and to let her out, she will pee by the back door. So, I was going to teach her to bark on cue, but she doesn't bark and i didn't really want to encourage that behaviour anyway.... and getting a dog door isn't an option, so instead I've bought Evie an electronic doorbell. The button is at nose height on the door frame of the back door (the door she always uses to go outside). The chime is out in the living room where we can hear it. My doorbell arrived 3 days ago. Day 1 I spent teaching Evie to press the button (at this stage the button was not on the door frame, but in my hand) and she only got clicked and treated when the button was properly and the chime made the noise. If she touched it and no noise came out, then no treat. Day 2 I put the button on the door frame and simply told Evie to touch it everytime she wanted to go outside. To begin with I would click and treat AND open the door for outside, but very quickly, just opening the door for outside was enough of a reward for Evie (She loves going outside to stalk our bunnies...) Day 3 (today). My family and I were all sitting in the living room talking..... we randomly hear a 'dingdong' and there's Evie sitting at the door waiting to get outside! Success!!! So proud of my Evie. She's still got a bit more training to go, but it's certainly a step in the right direction. !
