We're bringing you this product at the lowest price allowed by the manufacturer. That means this item isn't eligible for additional discounts or promotions.

As riders and online shoppers, we know it can be tough to buy a new bridle or pair of boots without trying them on. That's why we moved the fitting room to your living room (or barn)! From breeches to blankets, if you or your horse can try it on, you can return it, free! Just use the pre-paid return label included in your order within 60 days from the purchase date. And of course, please make sure the item is in like-new condition with original packaging (we said 'fitting room', not 'war room'!).

A favorite with top trainers, Happy Mouth bits are covered with a soft, flexible, yet extremely durable, apple-scented plastic which encourages acceptance and softness. The Happy Mouth Mullen Mouth King Dee has an inner core of twisted wire for more flexibility. All cheeks are stainless steel. 5", 5 1/2", 5 3/4". 20mm thickness.

    Happy Mouth Mullen Mouth King Dee is rated 4.7222 out of 5 by 18.
    Rated 5 out of 5 by from Horse Loves It My horse has been using this bit for years. I bought another one of these for his new show bridle because he loves this bit. He has a sensitive mouth, but takes this bit with ease.

    Rated 5 out of 5 by from Good Results My gelding has responded very well to this bit. I made the change two weeks ago. Heis now working with a softer more responsive mouth.

    Rated 5 out of 5 by from Really Nice I really like this bit, o stared a young, EXTREAMLY sensitive horse over fences and she did really well! a plain snaffle was still to much for her, we tried this and it immediately made a difference.

    Rated 4 out of 5 by from Great bit! Wears down quickly, though... This bit is very nice. I love the Dee ring for showing and my horse loves the gentle and chewy rubber! Unfortunately, he loves it a little TOO much, haha! He has chewed through 5 of these in the last year! I'm disappointed on durability (but maybe it's just my horse that has a chewing habit...) but he works well in the bit so we're keeping him in it. I think we're going to try wrapping it in latex (which I'm sad to see SmartPak doesn't offer!). All in all, great bit, just a little disappointed about durability. But, I understand that's what you get for having a rubber bit!

    Rated 4 out of 5 by from Soft and Simple Communication I love the fact that it is a very mild bit with no joints or moving ring parts. My mare seems to have a very sensitive mouth and I needed something that would provide soft and simple communication.

    Rated 5 out of 5 by from Training made easy I recently purchased one of these for myself, because at my barn we only have one, and almost all the new, uneasy horses, as well as some of the laid back horses, all need to use it. The bit was used two or three times a day, and had stayed in incredible shape and pretty clean, considering how much it is used. An added bonus is that the reins don't work their way to the straight part of the dee ring like it can with most other dee rings. This is a great training aid and incredibly durable!

    Ever since I was the girl with 1,000 breyer horses and the raggity braid in her hair, I was always obsessed. In second grade I moved into a town with a barn right down the street, which is when I started taking lessons...
