How does Enzo view his relationship with his owner, Denny?

Enzo views his relationship with Denny as one of love and respect, which is central to the emotional core of "The Art of Racing in the Rain." Throughout the story, Enzo, the dog, offers insights into his deep bond with Denny, which transcends a simple owner-pet dynamic. Enzo recognizes Denny's struggles and triumphs, emotionally supporting him through various challenges in life. Their relationship is characterized by mutual understanding, affection, and loyalty, demonstrating a profound connection that goes beyond the typical master-servant dynamic. This love and respect is what drives Enzo to observe and reflect on human behavior and relationships, further emphasizing the depth of their bond.

The other options do not accurately encompass the complexity of their relationship: Enzo does not see Denny merely as a master or servant, nor do they have a casual acquaintance relationship. Moreover, the notion of viewing their relationship as burdensome contradicts the deep emotional ties Enzo expresses throughout the narrative.
