Choosing between a collar or a harness — and selecting the right type of each — is an important decision for every dog owner. It’s not just about style or trend; the equipment you use directly affects your dog’s comfort, safety, and behavior, especially during walks or training sessions.
With so many options available, it’s easy to feel overwhelmed. In this article, you’ll learn how to choose the right collar or harness for your dog based on their size, temperament, walking habits, and specific needs.
Collar vs. harness: what’s the difference?
Both collars and harnesses serve essential purposes, but they function differently and are best suited for different situations.
Collar
- Wraps around the dog’s neck
- Ideal for holding ID tags and everyday wear
- Good for well-trained dogs that don’t pull
- Not recommended for dogs with respiratory issues or neck sensitivity
Harness
- Wraps around the dog’s chest and shoulders
- Provides better control and distributes pressure more evenly
- Ideal for dogs that pull, have health issues, or are in training
- Can help reduce risk of neck injuries
Many owners choose to use both: a collar with ID tags and a harness for walking.
When to choose a collar
Collars are simple and convenient, and they remain the most common choice for everyday use.
Best suited for:
- Dogs that walk calmly on a leash
- Dogs who are already leash trained
- Short walks or quick outings
- Dogs with no history of breathing or trachea issues
However, collars may not be ideal if your dog:
- Pulls strongly on the leash
- Has a small or fragile neck
- Is prone to collapsing trachea (common in small breeds)
- Has had prior neck injuries or disc problems
If you use a collar, ensure it’s properly fitted and doesn’t apply too much pressure.
Types of collars and their uses
Flat collar
The most common type, perfect for daily wear and ID tags.
- Adjustable
- Available in many styles and materials
- Best for calm, leash-trained dogs
Martingale collar
Also known as a limited-slip collar, designed to prevent dogs from slipping out.
- Ideal for dogs with narrow heads (like greyhounds)
- Tightens slightly when pulled, but not enough to choke
- Not meant for unsupervised use
Head collar (e.g., Gentle Leader)
Gives control by guiding the dog’s head.
- Useful for strong pullers
- Requires training to use properly
- May cause discomfort if not fitted correctly
Choke or prong collars
These should only be used under professional supervision, if at all. They can cause injury, fear, or anxiety if misused, and are not recommended for most pet owners.
When to choose a harness
Harnesses offer better control and comfort for many dogs, especially those that pull or need extra support.
Best suited for:
- Puppies learning to walk
- Dogs prone to pulling or lunging
- Dogs with neck or spine issues
- Brachycephalic breeds (like pugs or bulldogs)
- Senior dogs needing support
Harnesses help distribute pressure across the body instead of concentrating it on the neck, which makes walking safer and more comfortable.
Types of harnesses and their features
Back-clip harness
The leash attaches to a ring on the back.
- Great for calm dogs
- Easy to put on
- Comfortable and gentle
Front-clip harness
The leash attaches at the chest.
- Helps redirect pulling
- Ideal for training
- May tangle under legs if loose
Dual-clip harness
Offers both front and back attachment points.
- Flexible for training and casual walks
- Allows customization of control level
- Often used with double leashes
Step-in harness
Easy to put on — the dog steps into it.
- Good for small dogs
- Less intimidating for nervous dogs
- Not ideal for heavy pullers
No-pull harness
Designed specifically to discourage pulling.
- Often includes a martingale-style chest strap
- Helps teach leash manners
- Should be used with proper guidance
Proper fit is everything
Regardless of what you choose, fit is the most important factor. A poorly fitted collar or harness can cause chafing, escape, or injury.
Tips for a proper fit:
- You should be able to fit two fingers between the collar/harness and your dog’s body
- The harness should not rub the armpits or restrict movement
- Make adjustments regularly as your dog grows or gains/loses weight
- Watch for red marks, fur loss, or resistance — signs of discomfort
Try different models if needed, and allow your dog to get used to new gear gradually.
Consider your dog’s lifestyle and behavior
Different dogs have different needs. Ask yourself:
- Does my dog pull or lunge on walks?
- Is my dog calm, reactive, or anxious?
- Do we take long hikes, short walks, or city strolls?
- Is safety or training the main priority?
- Does my dog escape from collars easily?
Matching your choice to your dog’s daily habits and personality will help you choose more effectively.
Combine tools for safety and training
In many cases, using a harness for control and a collar for ID is the best solution.
Tips for combining both:
- Attach ID tags to a flat collar
- Use a harness for leash attachment
- Consider a dual-leash system for advanced training
- Always supervise your dog while wearing gear
This hybrid approach ensures both identification and walking safety.
What to avoid
To keep your dog safe and comfortable:
- Avoid retractable leashes with collars — they encourage pulling
- Never leave choke or prong collars on when unsupervised
- Don’t force a harness on a scared dog — use positive reinforcement
- Don’t keep collars or harnesses on 24/7 unless recommended by your vet
Comfort, safety, and your dog’s confidence should always come first.
The right gear builds better walks
Walking should be a joy — not a struggle. Choosing the right collar or harness can make all the difference in how your dog behaves, how safe they are, and how much you both enjoy your time together.
Take the time to understand your dog’s body, energy, and habits. Try different models, adjust as needed, and pay attention to how your dog reacts. The right fit isn’t just physical — it’s also emotional.
With the right tools and a little patience, every walk can become a better experience for you and your dog.
