Harness or Collar? Here’s How to Choose What’s Best for Your Dog
I’ve trained hundreds of dogs over the past 12+ years, and I can confidently say this is one of the questions I get asked the most:
“Should I use a harness or a collar for my dog?”
The short answer?
It’s not a one-size-fits-all. Just like people, dogs have different bodies, personalities, and needs—and what works beautifully for one pup might be uncomfortable or unhelpful for another.
So today, I’m breaking it down to help you make the best choice for your dog.
1. Health & Body Type
Some dogs simply shouldn’t wear collars—especially those with:
Delicate tracheas (like Yorkies or Pomeranians)
Flat faces (like Frenchies or Bulldogs)
Spinal or neck sensitivities
A harness removes pressure from the neck and spreads it across the chest and shoulders, making it a gentler option for dogs with medical or structural vulnerabilities.
2. Training & Behavior
Is your dog still learning how to walk nicely on a leash? (No shame—it's a journey!)
Harnesses can help distributing pressure better and are a great idea for young dogs and puppies that are still learning how to walk nicely
Well-trained dogs who don’t pull might be fine with a simple collar.
A harness gives you more control and reduces the chances of accidental corrections that can happen with a collar and leash combo.
3. Sensitivity & Temperament
Just like us, some dogs are more sensitive than others.
Nervous or shy pups tend to feel more secure in a harness, which wraps snugly around their body.
Bold or easygoing dogs may not mind a collar at all.
Watch how your dog reacts to different gear—it’ll tell you a lot!
4. Type of Activity
Think about when and where you’re walking your dog:
For quick potty breaks or a walk around the block? A collar might be enough.
For hiking, training, or busy sidewalks? A well-fitted harness is safer and offers more control.
5. Comfort & Fit
No matter what you choose, the most important factor is fit.
A harness should allow full shoulder movement and not chafe or pinch. If a harness doesn`t fit well it can negatively impact movement patterns which can cause discomfort and tension (think uncomfortable shoes)
A collar should fit snugly (but not tightly) and sit high on the neck without slipping.
If your dog constantly scratches or seems uncomfortable, it may be time to try a different style or material.
My Take?
For most training sessions and training walks, I prefer a harness—especially for puppies, high-energy breeds and dogs still learning leash manners.
I also really like collars too (I typically use and recommend well-fitted Martingale Collars that prevent dogs from slipping out, or classic flat collars) Make sure your collar is comfortable and does not choke your dog.
But I do use collars too—for ID tags or calm walks with dogs I know and trust.
🌟 Final Thoughts
Whether you go with a harness or a collar, the most important thing is to observe your dog and understand where you and your dog are at - regarding training experience, skill levels, health, breed, and comfort.
