I am in my late 40's, and my mom owned a kennel my whole life, until she passed last year. That being said, I was amazed at the things I remember her doing as I read the lessons, but never really knew exactly why. It was so enlightening. I learned so much that made sense to me, now that I am older. The instructor was very clear, and understanding. My final word is, no matter how long you have been around animals, there is so much to learn in this course. Very well worth your time. Thanks for a wonderful job!
