Why is it not advisable to use treats when multiple dogs are present?

Using treats when multiple dogs are present is generally inadvisable because competing for food can lead to aggressive behavior. In group settings, dogs may become possessive or territorial over treats, which can escalate into conflicts. When one dog perceives another as a competitor for the treat, it may respond with defensive or aggressive behaviors, resulting in potential fights or injuries.

In contrast, while the other options do present some aspects related to dog behavior, they do not capture the primary concern associated with using treats in a group context. For instance, dogs can still show interest in food, even in groups, and the problem isn't that only one dog will benefit from the treat; rather, it is the potential for increased tension and aggression during the attempt to distribute treats that poses the most risk. Hence, the focus should be on managing the interactions among dogs to prevent negative outcomes.
