Rapid Interpretation of Heart and Lung Sounds: A Guide to Cardiac and Respiratory Auscultation in Dogs and Cats

Didn't come with password for website for audio portion of the book. Totally useless without it.

DO NOT PURCHASE KINDLE EDITION. THERE IS NO PASSCODE PROVIDED AND BOOK IS USELESS WITHOUT IT.WOULD LIKE TO GIVE NO STARS

This book is supposed to come with access to a companion website but requires a passcode. I will return it if I cannot obtain this passcode via Amazon. Thank you.
