Dog Harness Size Chart By Weight: Finding the Perfect Fit for Your Furry FriendSource:



As a responsible pet owner, you want to ensure that your furry friend is comfortable and safe whenever they go out for a walk. One of the essential items that you need for your dog is a harness. A harness provides better control than a collar, and it distributes pressure more evenly, reducing the risk of injury to your dog’s neck and throat. However, finding the right size of harness can be challenging, especially if you have a dog with an unusual body shape or size. This article will guide you through the process of selecting the right harness size for your dog based on their weight.

Choosing the right harness size is crucial for your dog’s comfort and safety. A harness that is too loose can slip off or twist around, causing your dog to escape or get injured. A harness that is too tight can restrict your dog’s movement and breathing, causing discomfort and distress. Moreover, an ill-fitting harness can cause skin irritation, rubbing, and chafing, leading to skin infections and other health problems.

How to Measure Your Dog’s Weight

The first step in finding the right harness size for your dog is to measure their weight accurately. You can use a digital scale or a bathroom scale to weigh your dog. If your dog is too heavy to lift, you can weigh yourself first, then weigh yourself again while holding your dog, and subtract your weight from the total weight. Make sure that your dog is standing still and looking straight ahead while you weigh them. If your dog is moving or wiggling, the measurement may not be accurate.

Factors to Consider When Selecting a Dog Harness Size

While the dog harness size chart by weight can be helpful, it is not always accurate for every dog. Some dogs may have a broad chest, a long body, or a thick neck, which may require a different size or type of harness. Therefore, you should also consider the following factors when selecting a dog harness size:


Some dog breeds have a unique body shape and size that may affect the harness fit. For example, Greyhounds and Whippets have a deep chest and a narrow waist, which may require a sighthound harness that is designed to prevent choking and pressure on the neck. Bulldog breeds and Pugs have a thick neck and a broad chest, which may require a harness with a wider neck and chest area.


Puppies and senior dogs may have different body proportions than adult dogs, which may require a different size or style of harness. Puppies may need a small and adjustable harness that can grow with them, while senior dogs may need a harness that is easy to put on and take off, with minimal pressure on their joints.

Activity Level

If your dog is active and likes to run and jump, you may need a harness that provides more support and stability, such as a front-clip harness or a no-pull harness. If your dog is calm and well-behaved, a simple and comfortable harness may be sufficient.

Health Conditions

If your dog has any health conditions that affect their breathing, mobility, or skin, you may need a harness that accommodates their needs. For example, if your dog has a collapsed trachea or arthritis, a harness that puts pressure on their throat or joints may worsen their symptoms. If your dog has sensitive skin or allergies, a harness that rubs or chafes may cause skin irritation or infection.

Once you have selected the right size and type of harness for your dog, you need to ensure that it fits properly. A well-fitted harness should be snug but not tight, with enough room for you to fit two fingers between the harness and your dog’s skin. The harness should not slide around or twist, and it should not put pressure on your dog’s neck, throat, or armpits.

To fit a dog harness properly, follow these steps:

  1. Put the harness on your dog and adjust the straps to fit their body.
  2. Check the fit by running your fingers along the harness and making sure that it is snug but not tight.
  3. Attach the leash to the harness and walk your dog around to see if they are comfortable and can move freely.
  4. Check the harness frequently to make sure that it is still secure and comfortable.



Choosing the right harness size for your dog is an essential part of being a responsible pet owner. By following the dog harness size chart by weight and considering other factors such as breed, age, activity level, and health conditions, you can find a harness that fits your dog comfortably and safely. Remember to check the fit regularly and adjust the harness as needed to ensure that your furry friend is happy and healthy.
