What is the recommended action to break a biting ferret's grip?

The recommended action to break a biting ferret's grip is to place the ferret under running water. This method is effective because it safely distracts the ferret and encourages it to release its grip due to the sudden change in environment and sensation. The cold water can startle the ferret, leading to the instinctual reaction to let go.

This approach is a safer alternative compared to other actions that might provoke further aggression or injury, both to the ferret and the handler. For instance, tapping the ferret on the nose may be perceived as a threat or agitation, potentially escalating the situation. Wiggling the mouth open or pulling the ferret away quickly can cause harm either by injuring the ferret or worsening the bite grip. Thus, using running water is a humane and effective method to handle the situation.
