Review the sentence:
Bonkers, our ninety-pound golden retriever, chews on furniture, __________,
and snots up the car windows—inconveniences we did not anticipate when we

The blank needs to begin with a simple present tense verb. You chose he drags us around the neighborhood during walks, which is an entire main clause and thus causes a parallelism error.
Before you continue, review the rules for parallel structure.
