What is the first action a veterinary technician should take when greeting a large dog for an examination?

Crouching down to the dog's level and extending your hand is an effective way to interact with a large dog during an examination. This approach helps to establish a positive and calm rapport with the animal, as it eliminates the intimidating presence of a tall figure looming over it. By lowering yourself, you convey a non-threatening demeanor, which can help the dog feel more at ease and comfortable with the situation.

Extending your hand in a gentle manner shows the dog that you are friendly and want to engage with it. Many dogs respond well to this behavior because it mimics the natural approach that canines use with each other, allowing them to assess your intentions safely. It's crucial to allow the dog to come to you rather than forcing interaction, as this promotes trust and reduces anxiety.

In contrast, the other actions may not create the optimal environment for the dog. Standing tall might intimidate the dog, while calling the dog's name loudly could startle it. Reaching out to pet the dog immediately might be perceived as invasive, especially without prior indications that the dog is comfortable. Thus, approaching the dog in a relaxed and approachable manner is the best way to begin the examination process.
