I can understand what you're saying. ZheZhe does the same with our lawn mower and weed eater, she charges and tries to bite the wheels on the lawn mower. Actually, anything that has a motorized sound. It can even be a child on a motorized toy and she tries to attack it. I don't know if she thinks it's going to hurt you or what. So, anytime we are out doors with any kind of machinary, she goes back inside. It's weird. But, I know where you're coming from. Makes you wounder what they're thinking.
