Although this book really needs an annual update, as do all veterinary and medical books, it is the only one of its kind and thus has to be recommended on these grounds alone. It is also eminently readable by the lay reader, but does not speak down to the professional. Most vets, vet nurses and grooms will need to refer to this book, or one like it ( if there is one) when dealing with donkeys or their hybrids, regardless of how much experience they have with horses. This book is an essential purchase for anyone who has dealings with donkeys.
