Have you tried using a grazing muzzle?  It's a wire muzzle that will allow her to drink but will make it impossible to crib unless she figures out how to get it off.  You will have to remove it at feeding time.  Here are a couple

In my garage i got an old paint can with (Pine tar and curry pepper I think) from my dads horse barn.  I was told to paint that on to the stall if I had a problem with cribbing.  As a side note I thought I had read somewhere that when a horse is cribbing it is not getting enough of some nutrient in its diet.

I have also heard that a horse will crib to produce saliva...in order to coat ulcers in the stomach. I know a lot of horses who, when treated for ulcers, gave up the habit of cribbing altogether. I know you aren't asking for reasons why, but knowing so could help find a better solution.

Good Luck!

  cayan pepper paste,mix a little bit of water and alot of cayan put it on the wood that she is cribbing on.she should stop because the taste is not nice.good luck..                    

Yep those are the down home cures. Sorry we didnt answer your question exactly. I've just never seen the cribbing collars work. Cayanne pepper is the old cowboy cure I was talking about. I use it in vaseline to treat some types of wounds.  Can't argue with an old cowboy. ;)

PS- FYI Last night, I accidently posted this under the gelding thread.  They are going to wonder what on earth I was thinking!  

If the cribbing is REALLY bad then you might want to look at surgical options.

I belive the elctrical collars only work when you push the button, not once they sense the action.

I've known horses so bad they cribbed in the pasture and on the water troughs.

Look into all possible causes with a good equine vet and follow the advice to a T.  That way you can systematically find a cure that works for you and the horse.

Thanks for everyone's opinions, and here is what I have to say on them (nothing bad)  Tried the muzzle, she broke 2 of them trying to crib and tried the other remedies, this horse loves hot sauce, and also the sprays and paints that are on the market ( I have a lot of money invested in anti cribbing.  I though that was right about the electric collar that you have to activate it yourself, I guess I should call the manufacturer about that.

And on the ulcer subject I am going to look in to that soon, as she is thin from cribbing and someone mentioned that she may not be bale to put the weight on because of this.

By the way she has crib of my geldings butt before and she is a nervous horse (you know not quite there).  I am also going to get a portable electric fence this year to change her pasture habits a little

Studies are showing that aprox 95% of racehorses have ulcers and 80%+ of horses that are shown, ridden, etc have ulcers.  Pretty scary statistics. Cribbing is often a sign a horse has an ulcer.

    My almost four year started chewing wood last March and a good friend told me about a product to use.  She said chewing wood is a sign he may have an ulcer or be developing one.  When horses are trailered, stomach acids can build up and cause an ulcer and I do travel with my horse quite a bit.  Miracle Clay is a Dynamite product and is a natural substance found in the earth.  You mix it with water to make a thick liquid and then give about 1/3 of a syringe before trailering.  It coats the stomach and prevents the acids from harming the stomach.  I gave this to my horse everyday for a month and then give it to him anytime I trailer him.  Guess what - he stopped chewing wood after about 5 days and hasn't done it since.

     A container costs about $25 and I'm still on the same container.  You don't have to refrigerate it or anything.  I keep several jars of it at the barn, trailer, and at home as I used it last summer on myself when I got stung by bees.  It's a great drawing agent as well.

    The other product I've heard of is aloe juice.  You give 1 cup am and pm everyday and it must be kept refrigerated.  Wal-Mart carries it.  I prefer the Miracle Clay as it's a lot less expensive and you don't have to give it everyday. 

     I have heard of great results from the aloe juice as well.

    Miracle Clay can only be bought through Dynamite Product distributors, but you can do a search on the web and find lots of them.

    While it may not cure a long time cribber, if you can provide relief to your horse why not try it.  You can also go the route of a vet exam, they have to scope them and gastroguard is very pricey.  But that is another option.  Good luck.

 I looked up the miracle clay and it was actually more expensive than the aloe juice.  I went to Amazon.com and ordered a gallon of juice.  Including shipping it was just over $20.  They wanted 19.95 for the jar of clay plus shipping.  I am giving the juice a try on my TB mare.  She is an ex race horse that cribs.  After reading everyones comments, I am pretty sure she has ulcers.

Another product that is on the market is a simple nutrient-buffer. It does not require refridgeration, and the show horses I know get it 1x/day with AM feed. I have also heard of using milk of magnesia, Succeed paste (cheaper than Gastro Gaurd) and also a product called Rantidine - All much cheaper than the $30/day GastroGaurd!

That is pretty scary. I'll bet its from the overuse of bute. I tend to think cribbing is from either a neurotic thing (like weaving), a vitamin deficiency/imbalance or teething. Good luck to all of us in figuring out which one it is!

BE VERY CAREFUL OF THE AUTOMATIC COLLARS THAT SHOCK WHEN THEY CRIB!!!!! Ive seen one of these tried and it was horrifying. After a jolt on mild setting the horse panicked. This in turn caused the collar to shock again which caused a loop of panic and shock, the panics made it dangerous to get the collar off. The horse took a long time for it to trust the owner again. The horse wouldn't allow the owner to catch because it associated the owner with the shocking collar. There were good intentions, but it backfired. Have you tried the "Best friend" cribbing muzzle? http://www.valleyvet.com/ct_detail.html?PGGUID=EC35CD66-8288-4513-B05F-DA15D8834218&ccd=INK001

 My horse gets "nervous stomach" when boarded. I tried Hilton Herbs and the problem appeared to have gone away(he quit biting at his sides). He know longer needs it. I cant remember the name, but it had chamomile which also calms humans stomachs. I bought it from ChamisaRidge.com

Good luck.

I have to agree with HWBar, there are far too many good horses out there.

Besides if this horse chewing the wood or grabing it a sucking wind on it. If it is the latter the horse is an endorphin junky. When they grab it and suck it releases endorphins and they get into a zone like a runner. Either learn to live with it or get rid of the horse.

...Harsh words for someone who is just looking for a little insight and help...

That's funny. :) Im not going to play animal shrink but it sounds like cribbing is either a learned behavior or a neurotic compulsion. I think before I'd throw out the gelding with the bathwater I'd make sure he didnt have some vitamin deficiency and/or try him on a calming agent. If he's sucking for endorphins than that's an addiction and just like in humans some drugs will wean people off the  need.

OP have you ever tried any of those calming agents on him? I think they are herbal based.
