How Long Is That Dog?  Efa really, really wants a dog.  But not just any dog.  Efa wants Mister Long Dog! Her parents say maybe, but first Efa has to guess how long Mister Long Dog is. As long as a very long pretsel? As long as a very long scarf? How will she ever guess?

Awdur: John Bond; Addasiad Cymraeg: Sioned Erin Hughes.

Mae Efa yn ysu am gael ci. Ond nid unrhyw gi cyffredin, o na – mae Efa eisiau Syr Selsgi Hir! Mae ei rhieni'n dweud efallai …ond yn gyntaf, rhaid i Efa ddyfalu pa mor hir yw Syr Selsgi Hir. Mor hir â pretsel? Mor hir â sgarff wlanog? Sut yn y byd gall Efa ddod o hyd i'r ateb?
