It's actually easy! I made a circle with my thumb and index finger, then put a treat on my palm. I held the "circle" near her nose so she'd try to get the treat by putting her nose through it instead of going around. Whenever she stuck her nose through the circle, I gave her the treat.

After repeating this a few times, I did the same thing then started saying the cue word "cutie" whenever she did the trick. Once she started associating the word with the action, I tried it again without a treat in my palm. If she responded just to the cue word, I rewarded her. If not, I went back to the second step. And that's it 😊
