"This book is easy to read and has an excellent index for
finding information quickly and easily." (Journal of
the American Veterinary Medical Association, 15 June 2014)

"In conclusion, this is an excellent book, and I
thoroughly recommend it to anyone with an interest in ear
disease. The content is suitable for students, general
practitioners and specialists (I've found it very useful). It
is excellent value even at the current list prices, and a quick
online search revealed some good bargains. Otitis is very common
and this book will help clinicians have a major impact on the
welfare of their patients." (Veterinary
Dermatology, 15 November 2013)

"In my opinion, the authors have succeeded in providing a
clear, superbly illustrated atlas on ear diseases, which makes a
useful addition to the bookshelf of every small animal
practice." (Veterinary Record, 21 September
2013)

"This collection of more than 400 clinical images
explained by a dermatologist and a surgeon represents a very nice
way for practitioners and vet students alike to learn more on ear
diseases, their diagnosis and treatments." (Vets
Today, 1 June 2013)

"This book is very thorough and covers the topic concisely
with the exception of treatment indications. Other than that, this
atlas is a great addition to a practitioner's library."
(Doody's, 17 May 2013)

"Any vet student or practitioner will find this an
outstanding key to assessing ear conditions and making an accurate
diagnosis." (Midwest Book Reviews, 1 May
2013)

"This is a carefully thought out and well written
publication . . . Photos of an excellent quality complete the
picture of a well turned out atlas at a reasonable price missing
only referral reading lists." (EJCAP, 1 March
2013)
