Jess the Lonely Puppy (Animal Stories #6) by Holly Webb

When Chloe's big brother Will breaks his leg, he's stuck in hospital for weeks. Mum and Dad are frantic, and there's no one to look after the family's lively Border collie puppy, Jess.

Jess is miserable and lonely, and so is Chloe. But Chloe doesn't really like dogs, and Jess only wants Will. Can the two of them ever be friends?
