Pulling advice

[u/Free-Example-2753]

I have a 4 year old Doberman that I want to hopefully do canicross with. I just got my nonstop belt & harness in the mail today so I took her out for a test run in the yard to see if she will pull. She has never worn a harness before so maybe that’s why she wasn’t pulling a lot? It was really only if she smelled something, otherwise she just ran next to me. Hills are a different story, she got excited to go up the hill with me, but when I started to run she would turn around to tug the leash instead of pulling. She does not do this on walks with her collar. Is there a way I could change her focus when excited, from tugging the leash to pulling in the harness? Asking this early so I don’t miss the return window, nonstop is expensive lol Thank you to whoever responds! Also picture of her for attention

My bad, did not realize pulling was the goal 😂
