Have you ever seen a dog walking down the street wearing a harness that is either too big or too small? It’s not a good look. Picking the right size harness for your pup is important for comfort and safety reasons.

Keep reading to learn how to measure your dog for a harness and find what size harness for my dog is best.

Harness Size Matters 

When finding the best-sized harness for your dog, size matters. A too large harness will be uncomfortable for your dog to wear and can cause chafing. A too small harness will be constricting and could cut off your dog’s circulation. In extreme cases, a too-tight harness could even cause respiratory problems. It’s important to find a size that is just right.

Step 1: Measure Your Dog 

The first step in choosing the perfect dog harness size is to measure your dog. You’ll need to take three different measurements to get the best fit.

First, you’ll need to measure your dog’s neck. To do this, simply wrap a flexible tape measure around the thickest part of the neck and chest and note the number.

Next, you’ll need to measure your dog’s chest. Once again, wrap the tape measure around the widest part of their chest and note down the number.

Finally, you’ll need to measure your dog’s back area up to its front leg area. This will give you an idea of how long the harness needs to be comfortable for your pup.

Step 2: Consider Your Dog’s Weight 

In addition to taking measurements, you’ll also need to consider your dog’s weight when choosing a harness size. Heavier dogs will need a bigger and sturdier harness, while smaller dogs can get away with a lighter and narrower one.

If you’re unsure about what size or weight category your dog falls into, you can always consult with your veterinarian or a pet store professional for help. They’ll be able to tell you which size is best based on your individual dog’s needs.

Step 3: Choose The Right Type Of Harness 

Many different types of harnesses are available on the market today, so it’s important that you choose one that’s right for you and your pup. You can also get help from the dog harness size chart.

A simple padded vest-style harness should suffice if you plan on using the harness for everyday activities like walks and hikes.

However, suppose you’re looking for something more heavy-duty that can be used for activities like running or sledding. In that case, you’ll need a more robust harness that provides additional support and protection.

Specialty harnesses are also available for small dogs and puppies who might require a bit more support than their larger counterparts.

Other Considerations 

In addition to finding the right size and weight, there are a few other factors you’ll want to consider when picking out a harness for your pup. 

Fitting Of Harness

You’ll first want to consider how well the harness will fit your dog. You don’t want it to be too loose or tight; right is key. A good way to test this is by putting the harness on your dog and then trying to slip two fingers underneath the strap that goes around its chest. If you can do this easily, the harness is likely too loose and slide over the dog’s head. On the other hand, if you can’t slip any fingers underneath, it’s probably too tight.

The Sensitive Skin Of Dogs

Some dogs have sensitive skin and may do better in a harness made with breathable fabric like mesh or nylon. If your dog falls into this category, steer clear of harnesses made with heavy-duty materials like leather that can chafe the skin. Older dogs or those with arthritis may prefer a padded or cushioned harness for additional walking comfort. 

Weather Conditions

If you live in an area with extreme weather conditions (hot or cold), make sure to choose a harness that will be comfortable for your pup in those conditions.

The Activity Level Of  The Dog

If you have a high-energy dog, you’ll want a harness that can stand up to lots of wear and tear. Conversely, if your dog is more low-key, you may want to opt for a harness that’s more comfortable and less rugged.

Breed Of Dog

Some harnesses are specifically designed for certain breeds of dogs, so be sure to check before making your purchase. Certain breeds have unique characteristics that require specific types of harnesses. dog collar

For example, short-nosed breeds like pugs and bulldogs tend to have respiratory issues, so they need a harness that doesn’t put any pressure on their neck or throat. Breed like a golden retriever and Scottish terrier needs a small or medium-sized harness.

On the other hand, breeds with long bodies like dachshunds or corgis need a harness that’s designed specifically for their body type in order to avoid back problems. 

Style Of Harness

You’ll also want to consider style when selecting a harness for your four-legged friend. There are many different styles of dog harnesses on the market, so take some time perusing your options before making a decision. Do you want a no-frills utilitarian harness or something more fashion-forward? The choice is up to you!  

Price Range

Just like anything else, there’s a wide range of prices when it comes to dog harnesses. Be sure to set a budget before beginning your search, so you don’t get sticker shock when it comes time to purchase!
