In this guide, we will explore what makes a good harness for your Chihuahua, how best to measure them for that perfect fit as well as review our top five choices for your tiny friend.

Why Choose a Harness for a Chihuahua

When choosing a harness for your Chihuahua it is important to understand why collars may not be the best option.

With most breeds of dogs, particularly when they are puppies, there can be a tendency to pull when out on a lead and collar. This can cause a number of problems, firstly – it doesn’t make a good walk for anyone.

It can be stressful for the dog owner as well as the dog and make walking more of a chore than a pleasure.

Secondly, pulling on a collar can cause discomfort for the dog. This can have the adverse effect of increasing the pulling behaviour as the dog tries to escape the unpleasant sensation of being choked.

Thirdly, and most importantly, is the pressure this puts on your dog’s throat. When you walk a dog using a collar, it can put a lot of pressure on their throat – particularly if they pull. If your dog has a collapsed trachea, continuing on a collar will be wholly unsuitable – and a harness will help dramatically.

Chihuahuas are prone to a few difficulties around breathing and the throat area. One is pulmonic stenosis which restricts blood flow to and from the heart. One of the effects of this is difficulty breathing. A suitable harness will place less pressure on the throat and reduce the strain when out walking.

Because of the size of small breeds such as chihuahuas, Dachshunds and French Bulldogs – the risk of tracheal collapse from too much pressure is also a worry. A continued honking cough can be a sign of issues and in addition to considering harnesses – you should always consult your vet if you are worried.

What Size Harness for a Chihuahua?

It is crucial you consider the Chihuahua’s size and shape when buying a dog harness. An ill-fitting harness can be easily escaped from, not only when they pull but when they wriggle out whilst idle. As one reviewer online put it “I was left with a lead and harness with no dog”.

You can find out more about measuring your dog for a harness below, but let us discuss some of the basics.

For a very small or puppy Chihuahua you will want to look for sizes such as XX-Small and X-Small.

Generally these measure around the chest at about 29-35cm.

For adult chihuahua a chest Size roughly 36-50cm.

These sizes vary quite a bit depending on the manufacturer and retailer, so you should double-check it’s the right one for you.

You may also consider measuring the neck of the dog, especially if they have trachea issues.

How to Measure your Chihuahua for a Harness

How to Measure your Chihuahua for a Harness

For a complete guide to measuring any breed for a dog harness, you can read our complete guide. As a quick summary for fitting the perfect Chihuahua dog harness, here are the steps you should take:

  • Start by measuring the chest. Take a tape measure and find the widest part of your Chi’s chest. This is a few inches, or a few fingers, from the back of the dog’s front legs. Wrap the tape all around and make a note of the measurement. You now have the chest sizes of your dog to compare against the harness manufacturers measurements.
  • Add a couple of inches to the total. You obviously do not want the harness to be too tight, and also want to allow room for growth and slight weight gain. Adding a few inches allows you flexibility and most harnesses are adjustable.
  • Measure the circumference of the dog’s neck. Not all harnesses require the head to go through. However some do, and of those, some may not be adjustable. It is therefore important to measure the neck to make sure your dogs head will fit through and that you can remove the harness without tugging. Similarly, it cannot be too loose or your dog could escape.

Types of Dog Harnesses for Chihuahuas

There are several types of harnesses available. Not all are suited to every breed, and some just look silly on others. We’ve covered our choices of the best harness for Chihuahua’s in the section below – but if you’re still looking, these are the types of harnesses you’ll read about online.

  • Vest Dog Harness. These are the most basic types of harness, vest harnesses are usually the easiest to use and usually the more affordable out there. They are often made of nylon or mesh fabrics, are soft and lightweight. They often fit over the head and can be adjusted easily. The leash attachment point of at the back and they make great general walking harnesses, particularly for dogs who are new to harnesses or those who have a tendency not to pull.
  • Front clip or back clip Harness. Often recommended by dog trainers, these harnesses are secure, robust and can help your dog if they are a puller. There are various forms of this no-pull harness. One popular option is a harness with a D-ring (leash attachment point) at both the front (chest) and back (top). Using a double-ended training lead such as a Halti, the attachment clip can be clipped to both the front and back – similar to a horses reins. This not only helps to guide the dog but offers better control and a training method for when they start to pull while out walking.
  • Tightening or Control Harness. We wouldn’t recommend these, and they are best left to experienced trainers. However, these are designed to tighten when your dog pulls on the leash. Though this can help fix bad behaviours in your dog, it can lead to discomfort in less experienced hands.
  • Leather Harnesses. It may seem obvious to describe a leather harness as simply a harness made from leather. What should be noted from these are that they can act as more than simply a fashion statement. If you’re looking for something practical – consider those designed to reduce pulling and aid with training. Also, look for harnesses which are not only comfortable but do not rub or chafe the dog’s skin, particularly when wet.
