What action enhances the seriousness of interference with police service animals?

The action that enhances the seriousness of interference with police service animals is throwing an object or substance. This act can be perceived as an aggressive or hostile action aimed at a police service animal, which not only distracts the animal but can also lead to injury or distract the handler. Throwing an object or substance creates an immediate threat to the safety and effectiveness of the police service animal, thereby escalating the situation.

In contrast, while obstruction of justice, direct physical attack, and failure to obey commands can all play significant roles in the context of law enforcement and animal interactions, they do not specifically address the concern related to interference with police service animals. Direct physical attacks may encompass various forms of aggression, but throwing an object or substance is particularly notable for its potential to harm the animal and disrupt law enforcement efforts in a more immediate and tangible way.
