Features to Consider in the Best Harness for Jack Russell

Considering that the build quality, size, design, and comfortability of harnesses for Jack Russells vary across brands, you can be confused about which harness to go for, especially if you’re a new dog owner.

Regardless of the sex, age, or personality trait of your Jack Russell, you will need to consider the following features when choosing a harness for your dog. Additionally, the following table provides a quick breakdown of the key features.

Although Jack Russells are relatively small dogs with a standing height of around 10 to 15 inches, the size still varies across the breed depending on the age, sex, ancestry history, and the diet you’re feeding your dog. That means there is no fixed-size harness that can fit all Jack Russells.

You should, therefore, measure your dog’s size to ensure that you are buying the right size of a harness. Usually, you will want a harness that will not be loose in a way that the JRT can slip out and not too tight to cause pain.

Typically, you’ll want a harness that you can’t pull over the head of the dog, yet you can fit two fingers under the straps. If you are uncertain of the right size for your dog, it is advisable to go for a customizable fit harness such as PoyPet 2019 Upgraded No Pull Dog Harness.


Jack Russells are energetic and hyper dogs with a strong prey drive and will want to run around. They are also territorial and aggressive and will want to attack any person or animal intruding into their environment. That means you can expect your JRT to pull you around.

If you go for a back hook harness, your dog will be able to pull you much better using its chest. Therefore, it is advisable to go for a front hook harness such as the Ruffwear Front Range Harness.

With the clip-on front of the chest, the dog will have limited pulling power, giving you better control.

Reflective Straps

Although many dog owners think that reflective straps are just a fashion to make the harness appealing, it is more of a safety feature that you should consider when choosing a harness. The reflective straps reflect light to make the harness easily visible, improving the overall ease of spotting the dog.

These reflective strips are especially important when going out with your dog in the dark. Jack Russells are playful and tend to run around or run through your legs, and it can be challenging to spot them in darkness.

Usually, this increases safety risks such as accidentally stepping on your dog or the dog being knocked down by a car. The best way to reduce the risk is to get a dog harness with reflective stripes, such as the PoyPet 2019 Upgraded No Pull Dog Harness.

Buckle Isolation

Most high-quality Jack Russells’ harnesses come with buckles that help you tighten or loosen some parts of the harness, depending on the dog’s body. Although JRTs are double-coated, there can be skin irritation and discomfort if the harness buckle keeps on rubbing the dog’s coat.

Over time, the buckle can affect the quality of the dog’s coat or even make the dog unwilling to wear the harness. You can prevent this by getting a harness like the ThinkPet Reflective Breathable Harness. This harness has padding that helps prevent the buckle from directly touching the dog’s coat.


Considering that Jack Russell terriers are energetic and hyperactive, they engage in intense exercises and will need a breathable harness that can allow them to lose heat. That means you will need to make the right balance between the durability and breathability of the harness.

Therefore, it is advisable to get a harness with mesh ventilation, such as the breathable air mesh in the ThinkPet Reflective Breathable Harness. Typically, this will allow the dog to stay for an extended period with the harness, even during warm weather.

Frequently Asked Questions

Can I Leave My Jack Russell Terrier With a Harness All the Time?

Yes, you can leave your JRT with a harness all the time since it’s padded and comfortable. However, it is not advisable to let the dog sleep with a harness at night as the harness is meant for use during exercises, runs, and walks.

Should I Get My Jack Russell Terrier a Harness or a Collar?

It is advisable to get your JRT a harness as it helps to distribute the weight uniformly rather than exert pressure on the dog’s neck. Keeping in mind that JRTs are prone to respiratory health conditions, a collar might increase the risk.

Final Thoughts

The best harness for Jack Russell is padded and breathable, ensuring the dog is comfortable regardless of the weather condition. Although the right harness will depend on your preference, the above harnesses are versatile and have reflective straps that help make the dog visible even in darkness.
