Why Some Dog Trainers Advise Against Using Harnesses
For many dog owners, harnesses are seen as a safer, more comfortable alternative to collars. However, some dog trainers voice concerns about their use, particularly during the training phase. Understanding the reasoning behind this hesitation can help owners make more informed choices for their dog’s well-being and development.
1. Encouraging Pulling Behavior
One of the most frequently cited reasons trainers caution against harnesses is their tendency to encourage pulling. A well-fitted harness gives dogs full-body support, which means they can lean into it and pull without the discomfort a collar might cause. As a result, dogs may develop or reinforce poor leash manners, making walks stressful for both pet and owner.
2. Reduced Control for the Handler
Harnesses can limit a trainer or handler’s ability to correct unwanted behaviors. In training situations where precise control and redirection are necessary, a standard flat collar or training lead may offer more effective communication between human and dog.
3. Misaligned Training Goals
The objective of obedience training is to establish communication and trust while encouraging the dog to focus on the handler. Some trainers argue that harnesses enable dogs to ignore subtle cues and focus outwardly rather than remaining engaged with the person holding the leash. This may interfere with goals like loose-leash walking.
4. Behavioral Issues Going Unchecked
- Leash reactivity or aggression may become harder to manage with a harness due to less precise control.
- Dogs with high drive may use the comfort of a harness to fuel more intense reactions during walks.
- Training tools like martingale collars are sometimes preferred for these focused behavioral corrections.
5. Harnesses Masking Underlying Training Needs
Reliance on a harness can sometimes prevent dog owners from addressing underlying behavioral problems, such as pulling, lunging, or disobedience. Instead of teaching impulse control and engagement, repeated harness use may just manage — rather than resolve — these behaviors.
6. Physical Concerns in Growing Dogs
There are physiological implications, particularly in puppies or young dogs. Some trainers worry that a poorly fitted or overly restrictive harness might hinder proper gait development and skeletal alignment. Additionally, constant pressure on the shoulder or chest area may affect natural walking posture over time.
7. Better Alternatives for Training
For the purpose of structured dog training, many professionals prefer other tools, such as:
- Flat collars: Ideal for puppies or dogs learning basic commands.
- Martingale collars: Offer gentle correction while avoiding choking.
- Head halters: Help redirect focus and provide added control for strong pullers.
8. Situational Use of Harnesses
Despite their drawbacks in training contexts, harnesses have their place:
- For dogs with respiratory issues (e.g., brachycephalic breeds).
- In car safety setups requiring secure harness attachments.
- For service dogs that rely on specialized harness designs for aiding their handlers.
9. The Importance of the Right Fit
Regardless of whether a harness is used, fit and design are crucial. Poorly sized harnesses can chafe, restrict movement, or even allow escape. Trainers who do use harnesses often recommend front-clip designs over back-clip ones, as they reduce pulling and allow better direction control.
10. Final Thoughts on Harness Use During Dog Training
In the end, the choice between a harness and other training tools depends on your dog’s size, breed, temperament, and specific training goals. While harnesses may be suitable for certain cases, they can unintentionally delay effective training outcomes when not combined with structured obedience work. Consulting with a professional trainer and observing your pet’s behavior can help you make the most suitable decision.
Harnesses are not inherently bad, but understanding their limitations — especially when training a dog — is key to fostering a well-behaved, engaged, and content canine companion.
