Phase 1 - Introduce
Day one is hello.
Set the board on the floor of a room your dog already feels safe in. Press a small treat into the well. Wait. Don't call them over. Don't put their paw on the board. Don't make a sound when they sniff it.
If they take the treat, that's day one done. If they don't, leave the board there and try again in two hours. Some dogs sniff for a full day before they take the first treat. The plan accounts for that.
Day two is usually when treat-on-board stops feeling like a test. Some have already accidentally landed a paw on the pad. We mark that - quietly.
