Buyer’s Guide

Cavalier King Charles with Harness in Mouth
There are several factors to consider when purchasing a harness for your pup.

First up, we have our buyer’s guide. Free of charge, of course! We run you through all the factors you need to consider before buying a harness for your special canine. There’s more to your decision than you’d think, but we’ve made it simple for you. So, by the time you’ve got to the product section, you’ll be able to select the best one for your needs with ease.

Harness Types

Whatever type you choose, the primary purpose of a harness is to take the pressure and strain away from his neck. Instead, it spreads it across his chest and shoulders, which can be much safer and provide more control. But different harnesses have different purposes, so let’s look at what type suits you and your Cavalier King Charles Spaniel best.

Front Clip: The attachment clip is at the front of the harness on his chest plate. This teaches your Cav not to pull on the leash and redirect him when he does. This gives you more control during walkies and makes it a more pleasant experience for you both. Front clips are crucial for training or those who are forever pulling.

Back Clip: The attachment clip is between his shoulder blades, a convenient place to attach the leash. This harness type is ideal for those Cavs who are already leash trained and walk calmly.

Front & Back Clip: Many top-quality harnesses have both options, with clips placed in both positions. These harnesses are great for training because you can start with the front clip and proceed to the back as he gets more comfortable. It’s also good for dogs who have off days, where you need to use the front clip for greater control.

Step in Overhead: You also need to consider whether you need a step-in or an overhead harness. All harnesses are either-or. If you have an elderly, disabled, or injured Cav, an overhead harness is better. You simply place it over his head so he doesn’t have to move. Otherwise, it doesn’t really matter which type of harness you have.

Lift: A lifting harness is for those Cavs who have no use of their rear end, either during surgery recovery or old age. It works by taking the weight off his rear while he uses his front legs to walk. If this is the type of harness you need, we have a separate dog lift harness guide.


All Cavalier King Charles Spaniels are beautiful, but they are not all the same shape and size. Most Cavs, with an average chest size of 18 inches, likely fall into the small size group. But you need to measure him to make sure. But to achieve the perfect fit, it should be adjustable. And the more adjustment points there are, the more tailored it can get.

The right fit can make the harness experience a good or terrible one. If it’s too tight, it can cause injury, sore spots, and be uncomfortable. If it’s too loose, you do not have any control, and he will slip his harness. So, it’s important to look for a harness with at least three adjustment points.


The harness you buy should be good quality, and a major part of this is its materials. If it is made with flimsy fabric that is glued rather than stitched, you can be sure it won’t last long. Look for harnesses made with nylon or a polyester combination. And look for strong buckles and attachment points made with metal or robust plastic.

If it breaks, your Cav will run away. So, it’s important to pay a little bit extra to ensure you have a trusted harness. Plus, if it lasts for years, it’s better value for your money. We have found the optimum balance of quality and cost in our recommendations below.


Your Cavie deserves the best, and comfort should be a huge consideration. A padded harness prevents rubbing around his chest and armpits. The harness edges should be padded too or stitched to be soft rather than harshly cut material. A harness made from a breathable fabric, such as neoprene or meshed nylon prevents hot spots. It will make it more comfortable in the warmer months too.

Safety Features

Safety first, girls, boys, and Cavs! A harness is a safe choice for reducing windpipe strain and for allowing you to take control of him.

A handle is ideal for many circumstances. Whether that’s scooping him up from other dogs or helping him climb if he’s adventurous. The handle should be strong and stitched in place along his shoulders.

Reflective trimming and material is another safety feature that many high-quality harnesses incorporate into their design. Most have reflective stitching or trim around the edges, and some have reflective patches too. Look for a harness with reflective material visible from both the front and back for extra safety. Reflective material is important, especially during poor visibility walks. It keeps your Cav visible to you, others, vehicles, and cyclists.

Frequently Asked Questions

Here are a few of the most commonly asked questions regarding Cavalier King Charles Spaniels and their doggy harnesses.

Should I use a harness on my Cavie?

Yes, a harness is a must for all dogs, especially those with thin and delicate necks. It removes the pressure from the neck, distributing it across the chest. Like many small dogs, the Cav is prone to tracheal collapse, and a harness can help prevent this.

What is the best size harness for my Cav?

Cavalier King Charles Spaniels are part of the toy dog group. On average, they have an 18-inch chest, so a small-ish harness is likely. But not all harnesses have the same sizing range or instructions. Always measure your Cav as per the instructions on the advert. Adjustment points are key, and you should be able to fit one or two fingers between the harness and his skin.

How important is a correctly fitting harness?

This is the most important factor to get right. Get it wrong, and it can cause injury and make your Cav feel anxious if it’s too restrictive. He could also slip it and escape. Always measure, and check that it fits before removing the labeling just in case you need to return it for a different size.

Final Thoughts

The Cavalier King Charles Spaniel is one of the most beautiful pups in the world. He is graceful and sweet but also sporty and fun. So, it’s important that you find a harness that is comfortable, safe, and durable. By choosing one of our recommended options, you can be sure you will get all of that and more. Harnesses have many benefits, and they make the walking experience much more enjoyable for you both. Not only will your Cav look the part, but he will feel the part too. Everyone’s a winner.
