What are two benefits of proper training in animal restraint techniques?

Proper training in animal restraint techniques is crucial because it directly leads to increased safety for both animals and handlers. When handlers are trained in effective and humane restraint methods, they can manage animals in a way that minimizes the risk of injury to both the animal and themselves. This training provides handlers with the knowledge and skills necessary to anticipate an animal's responses and to apply appropriate techniques that reduce stress and anxiety for the animal, thereby promoting a safer environment.

Additionally, proper training contributes to improved procedure efficiency. When handlers are confident and skilled in their restraint techniques, they can perform procedures more effectively and with greater precision. This efficiency not only promotes better outcomes for the animal's care but also streamlines operations within a facility, allowing for better time management and resource allocation.

The other choices do not reflect the benefits of proper training. Increased stress is contrary to the goals of humane handling; complex procedures without proper training can lead to miscommunication and inefficiencies, and enhanced aggression in animals is not a desirable outcome and suggests a failure in training and handling practices. Thus, the correct answer highlights the fundamental benefits of training in restraint techniques: safety and efficiency.
