Eva argues that getting a dog would help her family by making them more responsible, providing companionship, and encouraging exercise through walks. While dogs entail costs like food, vet bills, and cleaning up after them, Eva believes the benefits of having a dog outweigh the downsides and promises to properly care for the dog by walking it regularly, picking up waste, paying for its needs, brushing and cleaning it, and keeping it healthy. Eva asks if she can have a dog, citing the benefits and her commitment to its care.
