Choosing the Ideal Harness for Your Puppy: Safety, Comfort and Growth
Bringing a puppy home is a time of joy and excitement. Among the many decisions to ensure its well-being and training, choosing the right walking equipment is paramount. Collar or harness? This question comes up frequently. While collars are traditional, harnesses are increasingly recommended, especially for young dogs.
The right harness is more than just an accessory; it's an essential tool for your puppy's safety , comfort, and physical development. A wise choice prevents injuries, makes leash training easier, and contributes to a positive experience during those first outings. This article aims to guide you step by step through this crucial decision, from ergonomics to proper fit.
Collar vs. Harness: Why a Harness is Often Preferable for a Puppy
Although a collar is essential for identification (wearing the tag), a harness is generally the safest and most comfortable choice for puppies, especially during their growth and learning period.
The Disadvantages of a Collar for a Puppy
Using a collar exclusively for walks presents several risks for a young dog:
- Risk of neck and tracheal injuries: Sudden traction puts excessive pressure on the cervical vertebrae and trachea, which can lead to injury, pain, or breathing problems.
- Impact on physical development: Repeated pressure can potentially affect the development of the spine and posture.
- Difficult learning: A puppy that pulls learns that pressure on its neck is normal to move forward, making learning to walk on a loose leash more difficult.
- Pressure on the eyes: In some breeds (brachycephalic), constant pressure can increase intraocular pressure.
The Advantages of a Harness for a Puppy
The harness offers a safer and more comfortable alternative:
- Increased safety: It distributes pressure across the chest, shoulders and back, preventing any strain on the neck and trachea.
- Better control: A well-fitting harness offers better control and minimizes the risk of escape.
- Optimal comfort: The absence of pressure on the neck allows the puppy to breathe freely, promoting a positive association with outings.
- Facilitates learning: It allows the use of educational methods based on **positive reinforcement** without creating aversion.
The collar remains essential for identification (tag) and can be used for specific exercises of very controlled heel walking, but the harness is by far preferable for daily walks.
The Different Types of Harnesses: Understanding the Models to Make a Better Choice

For a puppy, it's crucial to choose a harness that respects its growing physique. Here are the main models:
1. The H-Harness
The classic model. Two loops (neck and chest) connected by a dorsal and ventral strap.
- Advantages: Comfortable, easy to put on, versatile.
- Disadvantages: Can slip, offers moderate control.
2. The Y-shaped (Ergonomic) Harness
The model preferred by professionals. The strap passes between the front legs to form a 'Y' at the front, completely freeing the shoulders.
- Advantages: Very ergonomic, maximum comfort, ideal for growth.
- Disadvantages: Requires very precise adjustment.
3. The Vest Type Harness (Jacket)
Fabric harness covering a large part of the body.
- Advantages: Comfortable, warm, reassuring for anxious puppies.
- Disadvantages: Less breathable, often less adjustable.
4. The Anti-Traction Harness (Front Attachment)
Various models are available, featuring an additional attachment on the chest. When the puppy pulls, the leash gently redirects it to the side, discouraging the pull.
- Advantages: Very effective for teaching walking on a loose leash.
- Disadvantages: Excellent control, but must be well adjusted so as not to hinder the gait.
Comparative Table of Puppy Harness Types
| Harness Type | Shape | Attachment Leash | Key advantages | Ideal for |
|---|---|---|---|---|
| In H | H | Dorsal | Comfortable, easy to put on | Daily walks, calm puppies |
| In Y | Y/T | Dorsal | Ergonomic, freedom of movement, maximum comfort | Active, growing puppies |
| Anti-traction | Variable | Frontal | Effective against drafts, excellent control | Puppies that pull on the leash, training |
| Vest | Jacket | Dorsal | Comfortable, warm, reassuring | Small, cold-sensitive, anxious puppies |
Criteria for Choosing a Puppy Harness: The Importance of Fit and Safety
A poorly chosen or improperly fitted harness can be just as uncomfortable and dangerous as an ill-fitting collar. Here are the key elements to consider:
1. Size and Fit: The Essential Criterion
A puppy is growing rapidly, size is crucial:
- Measuring your puppy: Accurately measure the chest circumference and neck circumference.
- Adjustment points: Opt for a harness with several adjustment points (neck, chest, belly strap) to accommodate its growth.
- Check for chafing: Make sure the straps are not rubbing under the armpits.
2. Materials and Safety
- Material: Opt for Nylon, Polyester, or Neoprene for comfort and durability. Chest padding is a plus.
- Safety: Check the strength of the buckles and fasteners. The leash attachment rings should be made of welded and durable metal.
- Visibility: Reflective elements are essential for evening walks.
Once the harness is adjusted, you should be able to fit two fingers flat between the straps and your puppy's body. It shouldn't be too loose, but it should never restrict their breathing or movement.
How to Properly Put on and Adjust a Harness for a Puppy: Ensuring Comfort and Safety
Even the best harness is only effective if it's fitted correctly. Learning how to put it on should be a positive experience for your puppy.
1. Prepare the Puppy and the Harness
- Make it a positive experience: Associate the harness with treats and praise even before putting it on. Let him sniff it.
- Ideal time: Choose a time when your puppy is calm and relaxed.
2. Implementation Steps
For most harnesses:
- Head access: Lure your puppy through the head opening with a treat. Reward immediately.
- Passing the paws (if necessary): Do it gently, guiding it with a treat.
- Clip the loops: Attach the loops around the body.
3. Precise Adjustment: The Two-Finger Rule
Check these three areas using the two-finger rule:
- Check the neck: The strap should not choke, but it should not slip.
- Check the chest strap: This is the most important strap. It must be adjusted so that the horse doesn't escape.
- Check armpits: Make sure there is enough space to avoid painful irritation.
Puppies grow so fast! Check the harness fit at least once a week and adjust the straps if necessary. A harness that was perfect last month may now be too small.
Harness and Leash Training for Puppys: The First Lessons
It is a fundamental skill that requires patience, consistency, and positive reinforcement.
1. Gradual Introduction to the Leash
- At home: Let your puppy drag the leash (under supervision) so that he gets used to the sensation.
- Initial guidance: Use treats to encourage him to follow you gently. Reward him as soon as he takes a few steps by your side.
2. First Outings: Exploring the World Gently
- Calm environment: Start in a low-stimulating place.
- Short and frequent: Initial outings should only last 5 to 10 minutes.
- Let him explore: Allow your puppy to sniff for mental exercise, don't rush him.
3. Learning to Walk on a Loose Leash
The “Stop and Go” method is very effective for teaching your puppy not to pull:
- As soon as your puppy puts tension on the leash, stop immediately .
- Wait until the leash loosens (he may turn around, sit down).
- As soon as the leash is loose, go back to walking . Your puppy will learn that pulling = stopping.
- Changes of direction: Change direction without warning so that he keeps his attention on you.
- Treats as a guide: Hold a treat near your leg to encourage him to stay by your side.
❌ Mistakes to Avoid When Choosing and Using a Harness
Here are the pitfalls to avoid to guarantee a positive experience:
-
1. Choosing the wrong size or poorly fitted harness: A harness that is too loose allows escape, a harness that is too tight causes injuries and chafing.
Solution: Apply the two-finger rule and check the fit weekly.
-
2. Prioritizing aesthetics over ergonomics: A pretty harness is not necessarily comfortable or suitable for growth (favor Y-shaped harnesses).
Solution: The Y shape and comfort should always take precedence over patterns and colors.
-
3. Do not gradually accustom the puppy: Forcing the threading without positive reinforcement creates a lasting aversion.
Solution: Associate the harness with treats and let him wear it for short periods at home.
-
4. Letting the puppy pull on the harness (without correction): Although the neck is protected, this teaches him that pulling is effective.
Solution: Use the "Stop and Go" method and an anti-pull harness if necessary.
-
5. Using a harness unsuitable for the activity: A city harness is not a sports harness.
Solution: Choose a model suited to the main activity (Y-shaped for growth, anti-traction for learning to calm down).
-
6. Leaving the harness on the puppy permanently: This causes irritation and risks of snagging.
Solution: Remove the harness after each walk to allow the skin to breathe and reinforce the positive association with outings.
✅ Conclusion: A Wise Choice for Joyful Walks
Choosing a harness for your puppy is an important decision that will impact their comfort, safety, and leash training. By opting for an ergonomic model that fits well and is adapted to their build , you lay the foundation for peaceful and enjoyable walks for years to come.
Remember that introducing a harness and teaching your puppy to walk on a leash should always be done positively and gradually. Patience, consistency, and positive reinforcement are your best tools. Every puppy is unique and learns at its own pace.
