How to Choose the Right Harness or Collar for Your Dog

Introduction
Choosing a harness or collar for your dog is an essential decision if you want to ensure their comfort, safety and wellbeing on walks. With the sheer number of options on the market, it can be hard to know where to start. This guide will help you choose the accessory best suited to your dog, based on their build, their behaviour and their specific needs.
- Harness or collar: which should you choose?
The choice between a harness and a collar depends on several factors, in particular your dog’s breed, size, temperament and walking habits.
The advantages of a collar
- Ideal for dogs that do not pull on the lead.
- Lighter and less bulky than a harness.
- Makes it easy to attach an identification tag.
- Suited to dogs that already walk well on a lead.
The disadvantages of a collar
- Can put pressure on the trachea and cause injury, particularly in small, fragile breeds.
- Less suited to dogs that pull hard or that tend to choke themselves.
- Some dogs can slip out of a poorly fitted collar more easily.
The advantages of a harness
- Spreads the pressure across the dog’s chest, protecting the neck and trachea.
- Ideal for dogs that pull on the lead or that have respiratory problems.
- Gives better control over energetic or powerful dogs.
- Available in several models suited to different needs (walking, sport, training).
The disadvantages of a harness
- Can take longer to put on and adjust than a collar.
- Some dogs may feel uncomfortable at first and need time to adapt.
- Some poorly designed models can restrict the dog’s natural movement.
- How do you choose a suitable collar?
Types of collar
- Flat nylon or leather collar: ideal for well-trained dogs, comfortable and hard-wearing.
- Martingale collar: suits dogs whose head is narrower than their neck (greyhounds, whippets), and stops them slipping out.
- Half-check collar: to be used with care, mainly for training.
- Anti-escape or GPS collar: lets you track your dog’s movements, useful for dogs that tend to wander off.
What to look for
- Size and fit: a collar should be snug without being too tight. You should be able to slide two fingers between the collar and your dog’s neck.
- Material: go for comfortable, hard-wearing materials (leather, nylon, padded fabric).
- Buckle and attachment: a solid buckle and a strong attachment ring, to avoid any risk of breakage.
- How do you choose a suitable harness?
Types of harness
- Y-shaped (or H-shaped) harness: comfortable, it allows good freedom of movement and avoids chafing.
- Anti-pull harness: designed to discourage dogs that pull, by redirecting their pulling.
- Sport or pulling harness: ideal for activities such as canicross, hiking or cycling.
- Safety harness (with a back handle): perfect for older dogs or those needing assistance.
What to look for
- Material and padding: a harness with padding at the contact points is preferable, to avoid irritation.
- Adjustability: opt for an adjustable model so it can keep up with your dog’s growth or changes in weight.
- Attachment points: some harnesses offer a front attachment for better control over dogs that pull.

Mistakes to avoid
-
Choosing a collar or harness that does not suit the dog’s build: risk of chafing, discomfort and injury.
-
Neglecting the fit: an accessory that is too loose can let the dog slip out, while one that is too tight can be uncomfortable.
-
Using a choke collar permanently: these devices should be reserved for occasional training use, not as an everyday collar.
-
Not introducing it to your dog gradually: some dogs need time to accept their new harness.

Frequently asked questions
Should a puppy wear a harness or a collar?
A harness is often recommended for puppies, as it avoids putting strain on their developing neck. A lightweight collar can be used for identification.
How do you get your dog used to a harness?
Start by showing them the harness and rewarding them when they approach it. Put it on gradually while distracting them with treats, and make sure it is properly adjusted.
Can I alternate between a harness and a collar?
Yes. Some owners use a collar for quiet walks and a harness for more active outings. The main thing is to choose an accessory that respects the dog’s comfort.
Conclusion
The choice between a collar and a harness depends on your dog’s individual needs. A collar is practical for well-trained dogs, while a harness is preferable for dogs that pull or that have specific needs. By taking your companion’s build, behaviour and activity into account, you will be able to give them a comfortable, safe accessory. Take the time to try several models and to watch your dog’s reaction, so that you find the best option for their daily walks.
