。
She named her teddy bear Ted.
Literal
She [topic-は] her [genitive-の] bear [object-を] Ted [as-と] called.
The ~を~と呼ぶ pattern is the standard Japanese naming construction: 'to call X (by the name) Y.' The と here is the quotative/citational particle, marking the assigned name. クマ (literally 'bear') in this context is unmistakably a stuffed teddy bear rather than a real animal — context fills in the nuance that the bare noun クマ leaves open. The polite ~ました ending suggests a small narrative or report, possibly someone describing a child's behavior.
