A horse that walks off when you try to mount can quickly turn a simple task into a daily frustration. You line them up at the mounting block, put your foot in the stirrup — and off they go. Sometimes it’s a slow step forward, sometimes a sideways swing, and sometimes a complete walk-off.
Many owners are told their horse is being naughty, lazy, or testing boundaries. In reality, horses rarely move away during mounting for no reason.
Understanding why horses walk off when you mount is the key to fixing the issue safely, calmly, and long term.
This article explains the most common causes, how to identify what’s happening with your horse, and how to address the problem without creating tension or fear.

Why Walking Off Is So Common
Mounting puts a horse in a vulnerable position:
- Uneven pressure on the back
- Weight added suddenly on one side
- Limited ability to move freely
If a horse has learned that moving away relieves discomfort or confusion, they will repeat the behaviour. Over time, it becomes a habit rather than a conscious decision.
1. Discomfort When Weight Is Added
One of the most common reasons horses walk off when mounting is discomfort at the moment weight is applied.
This can be caused by:
- Poor saddle fit
- Pressure on the withers
- Tight girth
- Muscle soreness
Even a saddle that feels fine once mounted can cause discomfort during the mounting process.
Warning signs:
- Ears pinning during mounting
- Tensing through the back
- Stepping away as weight is added

2. Back Pain or Physical Issues
Horses with back, pelvic, or muscle pain may move to avoid discomfort.
This is especially likely if:
- The behaviour appeared suddenly
- The horse was previously good to mount
- There are changes in performance
Pain-related mounting issues should never be trained through.
👉 Important check: Is pain the reason your horse won’t stand still?
3. Inconsistent Training and Mixed Signals
Many horses walk off simply because:
- They were mounted while moving in the past
- No clear “stand” cue was taught
- Different riders allow different behaviour
Horses thrive on consistency. If sometimes standing still is required and sometimes it isn’t, the horse has no clear understanding of what’s expected.
4. Rider Balance and Technique
Rider actions play a big role.
Common issues include:
- Pulling on the reins for balance
- Heavy pressure on one stirrup
- Pulling the saddle sideways
This can feel uncomfortable or unbalancing to the horse, encouraging them to step away.
5. Anxiety or Anticipation
Some horses associate mounting with:
- Hard work
- Discomfort
- Stressful schooling
They may walk off in anticipation rather than defiance.
These horses often show:
- Tension before mounting
- Reluctance near the block
- Rushing once mounted
6. Poor Use of a Mounting Block
Mounting from the ground repeatedly increases strain on the horse’s back and saddle.
Without a mounting block:
- Pressure is uneven
- The saddle may twist
- Discomfort is more likely

How to Tell Which Issue Applies to Your Horse
Ask yourself:
- Did the behaviour appear suddenly or gradually?
- Does it happen with all riders or just one?
- Is the horse worse on one rein?
- Does it improve with a mounting block?
Sudden changes often indicate pain. Long-standing habits usually point to training or consistency issues.
How to Fix a Horse That Walks Off When Mounting
Step 1: Rule Out Pain First
Before training:
- Check saddle fit
- Consider back and dental checks
- Address any soreness
Never assume it’s behavioural until pain is ruled out.
Step 2: Reset the Mounting Process
Go back to basics:
- Ask the horse to stand next to the block
- Reward standing still
- Step away and repeat
Do not rush to mount.
Step 3: Break Mounting Into Small Stages
Reward the horse for:
- Standing still beside the block
- Standing while you put weight in the stirrup
- Standing while you pause before mounting
Progress gradually.
Step 4: Only Mount From Stillness
If the horse moves:
- Calmly step down
- Reposition
- Try again
Never mount while the horse is walking — this reinforces the behaviour.
How Long Does It Take to Fix?
Most horses improve quickly once:
- Pain is addressed
- Expectations are clear
- Consistency is maintained
Long-standing habits may take weeks, but progress should be steady.
When to Get Professional Help
Seek help if:
- You feel unsafe
- The horse shows pain signs
- Behaviour escalates
A qualified instructor or saddle fitter can often identify the issue quickly.
From One Horse Person to Another
A horse that walks off when mounting is not being difficult — they are responding to discomfort, confusion, or habit.
With patience, consistency, and attention to comfort, most horses can learn to stand quietly and confidently for mounting.
