My favorite detangler

Cowboy Magic: Detangler & shine for horses is the best detangler I've ever seen, hands down!

You can find it on Amazon.com (among other places) and it is available in different size bottles.

(google image, this is what the 4 and 16 Oz bottles look like)

Cowboy Magic also have schampoo and conditioner for horses but I have never tried either since I haven't had the urge to. But the detangler & shine is a must to have if you have a dog that mats and tangles! It also works on horses of course, and human hair.

Here's a google image that shows pretty well how awesome it really is.

Yes, it is capable of detangling dreadmats! And no I do not sell this stuff, I just really love it cause it actually works!
