Query: GREAT!!!

I am really into drawing and I am good at it. However, horses are probably the hardest animals to sketch because of their interesting shape and detail. This book makes it easy to draw all kinds of horses, starting with simple heads, advanced heads, and then progressing to full bodies, getting more challenging but keeping an easy pace as you go. Not to mention tips on keeping porportions straight, and supply suggestions. Now I really want to get "Drawing Dogs" by Walter Foster!
