The Best Large Dog Harness Buying Guide

A high-quality harness is an indispensable tool that almost all dog owners need. But while there are a variety of different harnesses on the market, relatively few are appropriate for large dogs. Some are simply too small to fit large breeds, while others lack the requisite strength and durability to withstand the wear and tear a large dog can dish out. Still others simply lack some of the most important features you would want in any leash.

But we are here to help. Below, we will discuss some of the most important features good harnesses possess, as well as explain the best ways to obtain a harness that fits your dog well.

But if you just stopped by to find some of the best large dog harnesses, you can just check out the table below.

Features of a Good Large Dog Harness

While no two harnesses are exactly the same, and different owners prioritize some features more than others, the best dog harnesses feature or provide the following:

Secure Fit

A harness that doesn’t fit your dog well can lead to chafing and discomfort, and it may even allow your dog to slip out of the harness – a truly frightening scenario. To a degree, the fit of a harness is influenced by the basic design and materials used in its construction, but most rely on adjustable straps to help ensure the best fit possible. While some harnesses only include one or two places in which you can adjust the length of the straps, the best harnesses typically provide four or five places to adjust the fit.

Multiple Attachment Points

All walking harnesses will obviously feature a place for you to attach the leash -- usually on the top of the harness, between your dog’s shoulder blades or a few inches behind them. While this placement works well for many dogs, it encourages others to pull on the leash. Accordingly, most of the best harnesses (especially those designated as “no-pull” harnesses) also include an attachment point on the front of the harness, which sits in the center of your dog’s chest. By attaching your leash to this ring, you can better control dogs that are prone to pulling.


Although some harnesses fit comfortably without padding, most of the best harnesses on the market feature padding on the straps and near the chest. These padded areas help to spread out the tension and help prevent the harness from chafing your dog’s skin or pulling out his hair.

Reflective Stitching or Trim

It is important to ensure you are visible to passing motorists and pedestrians; so, many premium harnesses feature reflective materials or stitching. However, you can purchase reflective stickers and similar items for harnesses that do not feature reflective surfaces, so this is not a deal-breaking criterion.

High-Quality Hardware

If you have a 5-pound Chihuahua, you don’t really need to worry about him breaking the metal D-ring or the buckles on his harness. But if you have a 150-pound Mastiff, you better select a large harness with hardware robust enough to withstand your dog’s strength. Generally speaking, premium harnesses come equipped with very robust D-rings and other accessories, which are strong enough to withstand your dog’s pulling and lunging.

Harness Sizing Guidelines

When you set out to purchase a harness for your dog, you’ll see that most are labelled by familiar sizes, such as small, medium and large. However, taken by themselves, these labels mean very little. One manufacturer’s “large” may be another manufacturer’s “extra-large.”

Trying to Measure a Dog

You always want to follow the manufacturer’s guidelines and sizing chart, as different harnesses fit in different ways. But, almost every harness on the market uses some combination of four different measurements to determine the proper size.

Chest Circumference

Chest circumference is the single most important measurement to consider when purchasing a harness. To obtain an accurate measurement of your pet’s chest, wrap a tape measure around the largest part of his rib cage, behind the front limbs.

Neck Circumference

Neck circumference is also an important measurement for ensuring a good fit, although not all harnesses list the neck circumference range for their harnesses. Measure your dog’s neck circumference the same way you measured his chest, by wrapping a tape measure around the largest part of his neck, near the shoulders.

Torso Length

Although torso length is not an important consideration for most harnesses, a few products recommend using this measure in addition to the chest and neck circumference. You’ll have to consult the manufacturer’s instructions for measuring your dog’s torso length, as different manufacturers measure torso length differently.


Although weight alone should never be used as a criterion for determining the proper harness size, it can be an important consideration with some harnesses. The stitching, metal hardware and buckles are typically rated for dogs of a given size, so you’ll want to be sure your dog’s weight falls within the range recommended by the manufacturer.

Owners explain that the harness fits very well and allows for a great range of motion, while still being secure and preventing dogs from backing out of the harness and escaping.

Although this is not a no-pull harness, many owners were pleasantly surprised that it stopped their dog from pulling. Additionally, while many of the owners found that the Ruffwear Web Master Harness was great for young, strong and active dogs, others found it very useful for older or injured dogs, as the fit allows owners to lift dogs gently and securely.

Some owners did complain that it was time-consuming to adjust the many straps at the outset, but once the proper fit was achieved, the strap buckles did not slip as occurs with many other harnesses.

Most owners who tried the Kurgo Tru-Fit found that it was easy to adjust and obtain a secure fit. Most dogs appear to find the harness very comfortable to wear, and the padded chest plate did not rub, chafe or cause any problems.

A few users found the design of the rear strap to be slightly problematic, as it moves around a little bit, but other owners failed to mention this at all. A very small number of customers also complained about the front clip coming unfastened. Additionally, a few owners noted that their dog was able to chew on the front strap, which could lead to problems.

User Reviews

The DEXDOG EZHarness received mostly positive reviews from customers who tried it. Most owners agreed with the manufacturer’s claim that this is one of the easiest harnesses to put on, and many found that it was very helpful for dogs who become anxious when a harness is placed on them. Several customers were also happy to find that this harness did not slide up to the neck region when under tension, which is very important, especially for smaller dogs or those with some health conditions.

However, the DEXDOG EZHarness also received its fair share of complaints, primarily relating to its durability and strength. While the manufacturer has upgraded the D-ring used on the harness, some customers reported that the stitching tore or the straps simply came apart. Accordingly, this is not a great choice for large, strong dogs who pull during walks.
