"It is an excellent addition to the library of any board-certified veterinary dermatologist, resident in a veterinary dermatology program, and veterinary clinician with a special interest in companion animal dermatology." (Vet Med Today, 15 June 2010) "Hair Loss Disorders in Domestic Animals is the first book to exhaustively review a subject that is such a common clinical problem. This book is well organized and easy to read. It initially provides a concise, understandable review of hair follicle biology that is essential for understanding the pathogenesis of alopecic disorders, including excellent descriptions and histologic images of hair follicle anatomy and development." (Vet Med Today, August 2010)"Provides a concise, understandable review of hair follicle biology that is essential for understanding the pathogenesis of alopecic disorders, including excellent descriptions and histologic images of hair follicle anatomy and development. This book contains an accumulation of essential, current information about alopecic disorders in animals that is not easily accessible from other sources. It is an excellent addition to the library of any board-certified veterinary dermatologist, resident in a veterinary dermatology program, and veterinary clinician with a special interest in companion animal dermatology." (JAVMA, June 2010)"This book is a delight. It is beautifully illustrated and concisely written. Not only does it provide much practical information but it makes a positive contribution to the discipline." (Veterinary Record, March 2010)"The editors and authors have done an excellent job of summarizing current theories of hair follicle development and function and presenting the most current information on hair loss disorders affecting domestic animals. ... This is the first book to present such detailed information. ... As such, it is a much needed textbook." (Doody's, April 2010)"This resource would be a worthy addition to the practice library, and very valuable to anyone tackling a dermatology module for the RCVS CertAVP. For someone embarking on a dermatology diploma, this text is worth it for the hair follicle biology chapter alone." (Veterinary Times, August 2010)
