The 20 Principles

by Roger Abrantes

Course Description

The 20 Principles All Animal Trainers Must Know is an online course, (also available as a seminar, workshop, book, and video). It explains clearly and concisely how we can train animals independently of species—dog, horse, cat, Guinea pig, marine mammal, etc.

The course has four lessons. The first three lessons consist of videos that you have to watch and study. In the fourth lesson, you read the textbook. You have a quiz for each lesson and the final quiz after lesson four. After having taken the final quiz, you earn a certificate from Ethology Institute.

As soon as you complete the quiz successfully, you will be able to print your certificate, show it to your friends, post it on Facebook or display it at your business.

Go for it and enjoy!
