Mandy loves animals and knows lots about them too! Both her parents are vets - so Mandy's always able to help her friends with their pet problems...Mandy's new neighbour, Paul, wants her to help him choose a pony from the local sanctuary.

Paul's pony is in a bad way, but Mandy knows he will take good care of it.

But people at school thinks he's been mistreating his pony.

How can Mandy show them they've got it all wrong?
