Horse Problems: Biting Colt

A Tale of Respect That Conquers All

Young horses go through stages of “mouthiness”. They start biting for a couple of reasons:

1. Baby horses, like baby humans, explore the world through taste. Putting their mouths and teeth on things gives them feedback about its composition and personality.

2. Young horses incorporate biting into their gymnastics naturally, and the foal may want to play. With no outlet but you, you become the target of the game.

3. They are afraid and biting in self defense.

4. They are developing a dominant personality (as in stud colts particularly but all foals in general) and are trying to dominate the person receiving the bite

Although our 4 month old colt is not yet to the point where we can put a halter on him easily when he is loose in the pasture, he has become much more friendly. We go out to talk to him frequently and make every effort to rub and pet him. When we enter the pasture, he is very curious and approaches us easily. However, given a chance, he wants to explore all over us, and frequently begins to mouth our clothes and then nip us.

This is behavior that needs to be discouraged.

He is getting larger. He tolerates and even seems to enjoy a sort of hug around his neck, but he turns his head to bite when we are standing at his side rubbing him or as we try to rub his head. Pushing his head forcefully away (picture left) has the potential to invite him to engage in nipping play or worse. He becomes more determined – pushing back and even showing his teeth.

“Tasting” everyting is very natural for colt shenanigans but cannot continue into “objection” nipping – particularly as this is a little stud colt who can easily start with play-nipping and launch right into dominance biting.

Possible Solutions

Another mare in the pasture
In the case of this colt, his dam (half-friesian, black & white) is as passive as they come. He shares a 3 acre paddock with just her, and she allows him to rear up and place his front feet on her haunches, bite her and generally disrespect her in every way. She has not really given him any manners at all.

If your mare is familiar with other horses at the ranch, another mare in her pasture may teach the colt some manners when he tries to bite. The dam will not let another mare hurt the colt, but she will usually not interfere in just general herd dynamics.

Pulling a whisker is uncomfortable. Other trainers have offered this suggestion. If you are able to pull a whisker each time he bites, he will soon learn that biting leads to discomfort. You must be able to do it serruptitiously, without fanfare and with perfect timing. In the case of our colt, there is really no time to grab a whisker before he can nip your forearm painfully. I’m not sure how well this routine will work in other situations.

Let’s go back to some basic natural horsemanship reasoning.


Although he is barely 5 mos old, he is large. I cannot get a halter on him because of the biting issue. I want to be able to control him before I try any type of biting discipline that might turn bad. I decided to start with using the round pen for halter-breaking him.

Round-penning is the basis for learning that “stop” is the answer to ending fearful pressure as well as giving respect to the handler. I’m older than I used to be, and he is bigger than he should be, but we accomplished his “stop and face” in a short amount of time. That left my approach and mounting the halter. Still no easy task, since I still had to get past the high-headed-nipping threat.

Then something radical happened. He got into a thicket that turned out to have barbed wire in it and sustained a gash on his rump. Now it became imperative that we get our hands on him and halter him IMMEDIATELY so the vet could take a look.

Danielle to the rescue.

She approached him after his “stand and face”, sidled up to “hug” him with the halter in her hand.

As he tolerated the hug, and when he did not expect it, she passed the halter rope under his neck and over his poll, then hung on for dear life as he took off like a wild horse. He dragged her all of the way around the round pen, one full circle, and she never let go until he stopped. It was a wild and crazy ride.

But it actually followed the rules of natural training – although a little dramatically. Because she was able to hold on to him to the end, he finally applied his “stop” to the fear (pressure) of dragging her around on his head.

Step one: He was frightened and began to run.

Rule 1: She went “with” him until he stopped. As our lesson progresses, this is an important rule. When we desensitize a horse we go “with” him until he stops, then the pressure is ended.

Timing: At the point where he stopped running, the pressure was lightened and quickly released as the halter was tied.

Success: He remembered the round-pen “stop” exercise and applied it. It worked. The pressure was released.

The Risk: This could have turned out badly. Had she turned loose while he was still running, it could have been a disastrous lesson. He would have learned just the opposite: Run and you can end the pressure.

I wish I had a video of the event. It was a dramatic “cowboy way”, and not what I would recommend as a way to halter-break a colt. But “all’s well that ends well”.

But that’s not the end of the story. We’re here to talk about biting.

You guessed it. That dramatic moment when the colt ceded respect from colt to human solved the biting issue! We are no longer his underlings, playthings, or equals but his benevolent masters. Mission accomplished. He has not even tried to bite since that moment desite the fact that he has had to have his wound irrigated and treated every day. He’s not exactly happy about the procedure, but biting has not entered the picture.

Obviously, I am not recommending that you wrestle your horse to the ground to stop the biting. What I am proposing is that you go back to some very basic “respect” lunging and other respect exercise. Do them hard and frequently until he realizes that you are master and he is lower in the pecking order of the herd.
