Which method is important when handling and restraining a large dog for examination?

Using a leash, gentle verbal commands, and positioning the assistant's body is the most effective method for handling and restraining a large dog during an examination. This approach emphasizes the importance of control and safety for both the dog and the assistant. A leash provides a means to guide and secure the dog, reducing the chance of escape or injury. Gentle verbal commands help establish trust and comfort, which can ease the dog's anxiety and promote cooperation. Positioning the assistant's body effectively allows for better control and stability, making it easier to manage the dog without causing distress.

In contrast, relying solely on a harness and muzzle may limit the effectiveness of the restraint. While these tools can be useful in certain situations, they do not facilitate the comprehensive control and communication needed to ensure a smooth examination process. Depending entirely on the owner's assistance may not provide sufficient security or control, as the owner may not always be able to accurately predict the dog's reactions. Lastly, applying physical restraints without considering the dog's behavior can lead to heightened stress or fear, making the examination more challenging and potentially unsafe for both the dog and the veterinary team.
