How does the director create comparson between Lennie and a dog when Lennie was drinking water?

The director likely uses visual and auditory cues such as showing Lennie lapping up water like a dog, setting up a parallel between the two actions. The director may also focus on Lennie's physicality and mannerisms to emphasize the similarities between him and a dog, such as his simple and instinctual behavior. Additionally, accompanying sound effects like slurping or panting could further reinforce the comparison.
