You should put this description in the title instead of just in the body! Otherwise people will not know when clicking on it.

A Theory of Relativity by Jacquelyn Mitchard seems to match your description.

"A terrible accident has left little Keefer orphaned but not unwanted. Devastated by his beloved sister's tragic death, twenty-four-year-old bachelor Gordon McKenna assumes that he will be entrusted with raising his niece... But the child's paternal grandparents have different ideas—and a fierce legal battle ensues..."

Quickly scanning Amazon's preview, Keefer sleeps in a dog bed.
