In addition to his audiobook and paperback, which are available everywhere books are sold, Dr. Dressler has also recorded a remarkable collection of audio seminars. Made for readers and veterinarians, Dr. Dressler discusses a topic related to dog cancer in more depth than can fit in his publications. He also answers listener's questions about their dog's cancer. Each seminar is available as a downloadable MP3 audio recording that you can listen to on your computer, smartphone or MP3 player. There are dozens of seminars available to choose from.
