DDog is now 5 years old and is a rescue. It's quite easy to train her to do things, but not to stop doing things. E.g she's not allowed upstairs - she does this several times a day and will go back down when told (as she is consistently), but this doesn't stop her doing it in the first place. Likewise sitting on the sofa - she will get off instantly when told (or if we walk in the room!) but it doesn't stop her getting back up. Every day she sticks her nose in the dishwasher when it's being loaded - is consistently told no and straight away takes her nose out of the dishwasher. However it's repeated in a groundhog day scenario. What should we be doing differently?
