Island of the Blue Dolphins

The black dog bared its teeth in warning, she was protecting her pups.

Far back in a corner was the half-eaten carcass of a fox. Beside it was a black dog with four grey pups. One of the pups came slowly towards me, a round ball of fur that I could have held in my hand. I wanted to hold it, but the mother leaped to her feet and bared her teeth.
