Why Does My Dog Pull on the Lead? Causes & How to Stop It

⏱ 7 minute read

If every walk feels like you're being dragged down the road, you're certainly not alone.

Lead pulling is one of the most common challenges dog owners face, whether you've got an energetic puppy discovering the world or an adult dog who's learned that pulling gets them where they want to go.

The good news is that most dogs don't pull because they're being stubborn or trying to dominate you. In many cases, pulling is simply a natural behaviour that can be improved with patience, consistent training and choosing the right dog harness.

Why Do Dogs Pull on the Lead?

Dogs naturally walk much faster than humans.

They're also constantly following exciting smells, sounds and sights that we barely notice.

When they're attached to a lead, they quickly discover something important:

Pulling often works.

If every time they pull forward they eventually reach the park, another dog or an interesting scent, they're unintentionally rewarding themselves.

The Most Common Reasons Dogs Pull

They're Excited

Many dogs simply can't wait to start their walk.

Common signs include:

• Racing towards the door before you've picked up the lead.
• Pulling harder near parks or open spaces.
• Constantly looking ahead rather than checking in with you.
• Increased excitement after missing a walk.

They're Following Their Nose

Your dog's sense of smell is thousands of times more powerful than yours.

Every walk is packed with fascinating scents, making it completely natural for them to investigate.

They've Learned That Pulling Works

Dogs repeat behaviours that achieve results.

If pulling gets them where they want to go, they'll continue doing it unless they're taught a different behaviour.

They Have Too Much Energy

A young Labrador, Springer Spaniel or Cockapoo with lots of energy may simply be eager to move faster than you're walking.

Regular exercise, enrichment and training all help.

They're Nervous

Interestingly, not every pulling dog is excited.

Some dogs pull because they're anxious and want to move away from something they're uncomfortable with.

This is especially common in rescue dogs or dogs lacking confidence.

Does a Harness Stop Pulling?

Short answer:

No.

A harness doesn't teach your dog not to pull.

What it can do is:

A good harness helps by:

• Providing better comfort – Pressure is distributed across the chest rather than the neck.
• Giving you greater control – Helping you guide your dog more comfortably.
• Reducing strain – Particularly useful for dogs that pull frequently.
• Making training easier – A comfortable dog is often more receptive to learning.

How to Stop Your Dog Pulling on the Lead

Reward Loose Lead Walking

Whenever your dog walks beside you with a loose lead, reward them with praise or a treat.

Dogs quickly learn which behaviour earns rewards.

Stop Moving When They Pull

Rather than allowing your dog to drag you forwards, simply stop.

Once they return to you and the lead becomes loose again, continue walking.

Consistency is key.

Change Direction

If your dog becomes focused on pulling ahead, calmly change direction.

This encourages them to pay closer attention to your movements.

Make Yourself Interesting

Bring treats, praise and occasional games into your walks.

Your dog should see you as being just as rewarding as everything happening around them.

Be Patient

Loose lead walking doesn't happen overnight.

Short, positive training sessions are usually much more effective than expecting perfection on every walk.

Should You Use a Collar or Harness?

For many dogs, a well-fitted harness provides a more comfortable walking experience than attaching a lead directly to a collar.

Harnesses distribute pressure across the chest rather than the neck, making them particularly useful for:

• Puppies – Young dogs are still learning and may move unpredictably.
• Small breeds – Smaller dogs can have more delicate neck and throat structures.
• Dogs that pull – A harness reduces direct pressure against the neck.
• Nervous dogs – A secure fit may help some dogs feel more supported.
• Older dogs – Senior dogs may benefit from comfortable and supportive walking equipment.
  

Our upcoming harness versus collar guide will explore the advantages and disadvantages of both options in greater detail.

Common Lead-Training Mistakes

• Expecting immediate results – Loose-lead walking is a skill that takes repetition and patience.
• Continuing forwards while the dog pulls – This unintentionally teaches the dog that pulling is effective.
• Using equipment as a complete solution – Harnesses can support training but cannot replace it.
• Only practising during long walks – Short sessions at home or in the garden can be extremely valuable.
• Failing to reward good behaviour – Dogs need clear feedback when they make the right choice.
• Giving mixed signals – Everyone who walks the dog should follow a similar training approach.
• Choosing an unsuitable environment – Beginning somewhere highly distracting can make learning unnecessarily difficult.
• Using a poorly fitted harness – Loose, tight or twisting equipment can make walks uncomfortable and reduce control.

When Should You Ask for Professional Help?

Consider seeking help from a qualified trainer or behaviourist if:

• Your dog pulls with enough force to cause injury.
• Pulling is linked to fear, lunging or aggression.
• Your dog becomes distressed around particular triggers.
• You are struggling to manage a large or powerful dog safely.
• You have trained consistently but are seeing little improvement.

Look for a professional who uses reward-based, force-free methods and who considers the reason behind the behaviour rather than simply suppressing it.

Frequently Asked Questions

Why Has My Dog Suddenly Started Pulling?

Changes in routine, energy levels, confidence or the walking environment can affect your dog’s behaviour.

A sudden change may also be linked to discomfort or anxiety. Speak to your vet if your dog’s behaviour changes significantly without an obvious explanation.

Does an H-Style Harness Stop Pulling?

Not by itself.

An H-style harness can provide comfort, adjustment and control, but consistent training is still needed to teach loose-lead walking.

Should I Use a Collar or Harness for a Dog That Pulls?

Many owners prefer to attach the lead to a correctly fitted harness because it avoids concentrating pressure around the neck.

A collar can still be worn to display identification details.

How Long Does Loose-Lead Training Take?

Every dog is different.

Some dogs begin improving within a few sessions, while others need several weeks or months of consistent training.

Should I Let My Dog Sniff During Walks?

Yes. Sniffing provides valuable mental enrichment.

You can use access to interesting scents as a reward for calm, loose-lead walking.

Are Retractable Leads Suitable for Pulling Dogs?

Retractable leads maintain tension as they extend, which can make teaching a consistently loose lead more difficult.

A fixed-length lead usually provides clearer feedback during training.

Ready for More Comfortable Walks?

Comfortable equipment can make lead training more manageable for both you and your dog.

Our lightweight, adjustable H-style harnesses are designed for secure and comfortable everyday adventures.

Final Thoughts

Lead pulling is common, particularly in young, energetic or curious dogs.

The most important step is understanding why your dog is pulling instead of assuming they are deliberately behaving badly.

Through positive reinforcement, clear boundaries, short training sessions and comfortable equipment, most dogs can learn to enjoy calmer walks.

A harness will not train your dog for you, but the right fit can provide a safer and more comfortable foundation for learning.
