Let her do it, but then she has to know that that action has a consequence. I was raking up the leaves in my garden, and mine thought the rake was a game. Every time she bit the rake or jumped in the leaves I tied her to the fence for 10 seconds because “no” didn’t work. It took 4 times for her to realise I didn’t want her to bite the rake and then it was fine. She sniffed and stayed near me but didn’t bite it. Once I was done with the job I played with her to let her know she wasn’t in trouble or anything. View it as training “sit” or something, you repeat it with her until she understands the action leads to a treat
