When it comes to choosing the right gear for our furry friends, we often find ourselves wondering: collar or harness? Both options serve their purpose, but understanding the difference between the two can help us make an informed decision. Collars are the classic choice, offering a simple and traditional way to attach a leash and display identification tags. On the other hand, harnesses provide added support and control for dogs, particularly those with medical conditions or a tendency to pull. So, whether you’re looking for a practical solution or considering your pup’s specific needs, let’s delve into the distinct advantages of collars and harnesses in order to find the perfect fit for your four-legged companion.

Purpose of a Collar


One of the main purposes of a collar for a dog is identification. By attaching a collar to our furry friends, we can easily display their identification tags, which typically include their name, owner’s contact information, and rabies vaccination details. In the unfortunate event that our beloved pup gets lost, having a collar with visible identification can greatly increase the chances of a successful reunion.


Collars also provide a means of control when walking or training our dogs. With a leash attached to the collar, we can guide and direct our furry pals, ensuring their safety while out and about. The collar allows us to communicate and establish boundaries with our dogs, making it easier to manage their behavior and keep them out of harm’s way.

Leash attachment

Another essential function of a collar is to serve as an attachment point for the leash. This allows us to maintain physical contact with our dogs while giving them the freedom to explore their surroundings within a safe distance. By attaching the leash to the collar, we can easily guide our dogs, ensuring they stay by our side and are prevented from running off.

Types of Collars

Flat Collar

The flat collar is the most common and traditional type of dog collar. It consists of a simple, adjustable strap made from various materials such as nylon or leather. Flat collars are lightweight and provide a comfortable fit for our furry friends. They are easy to put on and take off, making them a convenient choice for everyday use.

Martingale Collar

Martingale collars, also known as limited-slip collars, are designed to offer gentle control without choking or causing discomfort to the dog. These collars have an additional loop that tightens when the dog pulls on the leash but loosens when there is no tension. Martingale collars are especially useful for dogs with narrow heads, such as greyhounds and whippets, who might slip out of a regular flat collar.

Prong Collar

Prong collars, also called pinch collars, are controversial due to their appearance and potential for misuse. They consist of metal links with prongs that apply pressure to the dog’s neck when pulled. Prong collars are designed to mimic the way a mother dog corrects her puppies but should only be used under the guidance of a professional trainer or behaviorist.

Pros of Using a Collar

Easy to put on and take off

One of the significant advantages of using a collar is the ease of use. Collars are simple to put on and take off, providing convenience for both our furry friends and ourselves. This makes it quick and straightforward to get our dogs ready for walks or other activities.

Lightweight and comfortable for the dog

Collars are typically lightweight and comfortable for our dogs to wear throughout the day. They do not restrict their movement or cause any discomfort when properly fitted. This ensures that our furry pals can go about their daily activities without feeling weighed down or restricted.

Allows for easier control and leash management

Collars allow us to have better control over our dogs during walks or training sessions. With the leash attached to the collar, we can guide our dogs and correct their behavior if necessary. The collar provides a reliable point of contact, making it easier to manage the leash and prevent our furry friends from running off or engaging in undesirable behaviors.

Cons of Using a Collar

Limits pulling and choking

One disadvantage of using a collar is that it may not effectively deter dogs from pulling on the leash. Some dogs are more prone to pulling, and a collar alone might not provide enough control or discourage this behavior. Additionally, if a dog pulls forcefully, the collar can place pressure on the neck, potentially leading to choking or discomfort.

Potential strain on the neck and throat area

Collars, especially those that tighten when pulled, can put strain on the neck and throat area of our dogs. This is particularly concerning for breeds prone to respiratory issues or dogs with pre-existing neck injuries or conditions. The pressure exerted by a collar can exacerbate these issues and potentially cause harm to our furry friends.

Not ideal for dogs with respiratory issues or neck injuries

Due to the potential strain on the neck, collars may not be the best option for dogs with respiratory issues or neck injuries. Breeds such as Pugs or French Bulldogs, known for their brachycephalic respiratory syndrome, require special consideration when choosing a collar. Similarly, dogs recovering from neck injuries or surgeries should avoid collars that may aggravate their condition.

Purpose of a Harness

Distributing pressure evenly

Unlike collars that concentrate pressure around the neck area, a harness is designed to distribute pressure more evenly across the dog’s body. By utilizing a harness, we can spare our furry friends from potential neck injuries that may result from excessive pulling or directional changes during walks or training sessions.

No strain on the neck

Harnesses are particularly beneficial for dogs with neck issues or breeds known for their susceptibility to neck injuries. By shifting the point of contact away from the neck, harnesses alleviate strain and reduce the risk of exacerbating existing conditions. This is especially important when training or controlling our dogs during physical activities.

Suitable for dogs with health issues

Harnesses are often recommended for dogs with certain health issues, such as back problems or respiratory conditions. These conditions may require additional support, and a harness can provide a more comfortable and secure fit, reducing strain on the affected areas. It is always advisable to consult with a veterinarian to determine the most appropriate equipment for dogs with specific health needs.

Types of Harnesses

Back-clip Harness

Back-clip harnesses have the attachment point for the leash located on the dog’s back. These harnesses are easy to put on and remove and are suitable for well-behaved dogs that do not pull excessively. Back-clip harnesses provide good control and distribute pressure evenly, making them a popular choice among dog owners.

Front-clip Harness

Front-clip harnesses have the leash attachment point located on the dog’s chest. This design helps discourage pulling and redirects the dog’s attention towards the handler. With the leash attached at the front, we gain more control and are better able to guide our dogs, making it easier to manage their behavior during walks.

Dual-clip Harness

Dual-clip harnesses provide the flexibility of having both a front and back attachment point for the leash. This versatility allows us to choose the most suitable attachment point based on our dog’s behavior and training needs. Dual-clip harnesses provide increased control and are particularly useful for dogs that require additional guidance during walks or training sessions.

Pros of Using a Harness

Reduces the risk of neck injuries

One of the significant advantages of using a harness is the reduced risk of neck injuries. By distributing pressure evenly throughout the dog’s body, harnesses prevent strain and potential damage to the neck area. This is especially important for dogs that tend to pull on the leash or engage in sudden movements during walks.

Provides better control over the dog’s movements

Harnesses offer improved control over our dogs’ movements compared to collars. With the leash attached to a harness, we can more effectively guide and direct our furry friends. This enhanced control ensures their safety and allows us to discourage unwanted behaviors, making walks and training sessions more enjoyable for both our dogs and ourselves.

Ideal for dogs with respiratory issues or neck injuries

Harnesses are an excellent choice for dogs with respiratory issues or neck injuries. By eliminating pressure on the neck and throat area, harnesses provide a safer and more comfortable option. Breeds prone to respiratory issues or dogs recovering from neck injuries can benefit greatly from using a harness instead of a collar.

Cons of Using a Harness

May promote pulling due to the dog’s center of gravity

Due to the design of a harness, which distributes pressure across the body, some dogs may find it easier to pull during walks. The center of gravity shifts slightly forward when using a harness, potentially encouraging dogs to pull against the leash. It is important to properly train our furry friends to walk calmly with a harness to prevent reinforcing pulling behaviors.

May cause discomfort or rubbing if not properly fitted

If a harness is ill-fitted or incorrectly adjusted, it can cause discomfort or rubbing against the dog’s body. This can lead to chafing, skin irritation, or even sores in extreme cases. To prevent discomfort or injury, it is crucial to choose the right size harness for our furry friends and ensure a proper fit by adjusting the straps accordingly.

More difficult to put on and take off compared to a collar

Harnesses generally require a bit more effort and time to put on and take off compared to a collar. This can be particularly challenging if we have a wiggly or impatient dog. Additionally, some harnesses have various straps and buckles that may need adjusting each time, adding to the complexity of the process.

Collar vs. Harness: Which One to Choose?

When deciding between a collar and a harness for our dogs, several factors should be taken into consideration. These factors include the dog’s size and breed, behavior and training needs, as well as any existing health conditions.

First and foremost, we must consider the dog’s size and breed. Some breeds are more prone to neck injuries, respiratory issues, or physical deformities that require special care. In these cases, a harness may be the safer and more comfortable choice. Similarly, smaller dogs or toy breeds may benefit from the reduced strain offered by a harness instead of a collar.

Next, evaluating the dog’s behavior and individual training needs is crucial. Dogs that tend to pull on the leash or have difficulty following commands may require the additional control and redirection provided by a harness. On the other hand, well-behaved dogs that walk calmly on a leash may find a collar to be sufficient for their needs.

Lastly, it is vital to assess the dog’s health and any existing conditions. Dogs with respiratory issues, neck injuries, or recovering from surgeries may find a harness more suitable for their well-being. Consulting with a professional trainer or veterinarian can provide valuable insight and guidance in choosing the most appropriate equipment for our furry friends.


Both collars and harnesses serve important purposes when it comes to walking and training our dogs. Collars are ideal for identification, control, and easily attaching a leash. They are lightweight and comfortable for most dogs, but may not be suitable for those with respiratory issues or neck injuries. On the other hand, harnesses distribute pressure evenly across the body, reducing the risk of neck injuries and offering better control. They are particularly beneficial for dogs with health issues or those prone to pulling. When choosing between a collar and a harness, it is essential to consider our dog’s individual needs, behavior, and health conditions. By understanding the advantages and disadvantages of each, we can make an informed decision to ensure the comfort, safety, and well-being of our beloved canine companions.
