I rationalize it by my pony has more hair than I do, and it gets a lot nastier than mine does, but it gets washed less frequently so I need the 'good stuff', and since it's not as often that I use it, I go through about a bottle of it in about the same time it takes me to go through several bottles of my own and therefore costs the same.

Why "shampoo" a horse? It's bad for their coat, removes their natural waterproofing and warmth, and puts toxic chemicals on their skin to be absorbed.
A good currying is MUCH better for all concerned.
Wow. You don't own a white or gray horse do you?
Do you believe in using evil soaps or shampoo on yourself? Jeesh, get a grip. I don't think an occasional bath is going to harm your horse and I don't plan on using a shampoo containing "toxic chemicals".
