A woman gardens while her dog watches over her, and she envies him. The dog is quiet most of the time, answering the door with a few claw clicks, a deep woof, and a growl for strangers who come too near the garden. Kneeling in the wet Seattle dirt, the speaker finds that his silence is something she wants for herself. Digging calms her, letting go of her fear, her frown, and her own growls, much as running did when she was young along a boardwalk and the sand.
The poem keeps circling a handful of words, such as silence, growl, guardian, ancient, running and garden, and the repetition feels like the steady rhythm of digging or running. The mood is peaceful but wistful. The speaker is now grey and stiff, and she imagines having four legs and the wolf's old instincts. Her wish is not quite fulfilled at the end. She is still trying to understand what the dog's silence knows, and the poem suggests the answer may lie in the roots of the garden.
