The content reflects this vast experience and knowledge and we would like to acknowledge and thank all the professions for their willingness to share information and findings for the greater good of the health and welfare of donkeys. Special thanks must go to Neil Frame BVM&S CertEP CertVA MRCVS; RCVS Advanced Practitioner (Equine Practice) of Frame, Swift and Partners, Penrith. He has been enthusiastic in giving his time and experience to proof read and to provide the practical guidance on the relevance of the contents of this book to the practitioner and other professionals. His pertinent comments and advice have been valuable in ensuring this is a clear and easy reference tool for all those working with, or with an interest, in the health and welfare of donkeys. We would also like to thank our proof readers, who have given their time and been thorough in making this the professional book that we aspired to; Alison Hills, freelance proof reader, New Zealand and Liz Hazell-Smith, Research Assistant at The Donkey Sanctuary. No book would be complete without images and illustrations and we have used a comprehensive selection for reference. Kate Selley holds and manages a vast collection for The Donkey Sanctuary and she has used her drive, enthusiasm and positivity to obtain specific images for this book and also to select appropriate images from her collection. Her contribution to the book is much appreciated. This book has been organised into systems in order to make reference quick and easy. We have not included information about procedures or conditions for donkeys where they do not differ from those in horses and ponies, as there are already many excellent texts that describe these. Therefore, we have not included chapters on the Cardiovascular System, the Urinary System or Ophthalmology as we do not have any additional clinically relevant information that is specific to donkeys. Each chapter contains specific information on the clinical examination and procedures as well as the common conditions for that system and we have used signposting to indicate where other chapters may contain additional useful information. We do advise you to read the chapter on behaviour as this provides an explanation to the messages repeated throughout the book and is essential to your understanding of this unique animal.

At that time Glasgow Veterinary School had an equine parasite research programme which included studies on equine lungworm infection. As donkeys were frequently infected with this parasite Dr Svendsen travelled north to find the best way to deal with the problem. This led to close collaboration between myself and The Donkey Sanctuary and resulted in Betty and I becoming good friends. Since then I have seen significant advances in knowledge of health and welfare of donkeys largely due to the efforts of their charismatic champion. This latest Donkey Sanctuary publication “The Clinical Companion for the Donkey” would have pleased Betty enormously. It is a real Vade Mecum for everyone involved with donkeys to have by their side whether it be in developing countries where the donkey is a vital part of rural economies, or in parts of the world where they are kept either as pets or for leisure pursuits. Although much of the information provided in The Clinical Companion is relevant to donkeys worldwide some problems may be more important in certain areas - for example in Ethiopia it would be unusual to find an overweight laminitic donkey which, sadly, is not the case in many parts of Europe. The Clinical Companion begins with an excellent chapter on donkey behaviour the understanding of which is fundamental for the detection of welfare or health problems. I hope this valuable publication will be available to all who are involved with donkeys wherever they are and whatever their role.
