Small dogs need carefully chosen harnesses because of their delicate frames and unique body shapes. Unlike larger breeds, they are more prone to injuries caused by poorly fitted harnesses, so getting the right size is crucial for both their comfort and safety.
Safety Risks of Poor Fit
A harness that doesn’t fit correctly can lead to several problems for small dogs, including:
-
Chafing and Hair Loss: Tight or loose harnesses can rub against your dog's skin, causing irritation or hair loss.
-
Restricted Movement: A harness that's too big may limit your dog's natural movement.
-
Escape Risk: Loose harnesses can make it easier for small dogs to slip out.
-
Pressure Points: Tight harnesses can put uncomfortable pressure on sensitive areas of your dog's body.
Balancing Fit and Design
The right harness combines proper fit with thoughtful design. High-quality materials and smart design features ensure your dog stays comfortable and secure.
"Each piece is made to order so we can closely inspect each item and provide your pet the uncompromised quality they deserve." - Susan Lanci Designs [2]
When choosing a harness, consider these key factors:
Body Type Considerations
-
Measure your dog’s neck just below where a collar would sit.
-
Measure the chest at its widest point.
-
Take into account any breed-specific traits, like a long body or broad chest.
Design Features
-
Look for adjustable straps to ensure a snug, custom fit.
-
Choose designs that evenly distribute pressure across the chest.
-
Opt for soft, flexible materials that move with your dog.
Keep in mind that harness sizes vary between brands. A medium size in one brand might be labeled as extra-large in another [3].
"The quality, style and ease of maintaining these beautiful pieces is outstanding. Each piece is lovely and comfortable for my sweet pups." - Terry Fowler [2]
A well-fitted harness does more than just keep your dog safe - it should also enhance their natural shape and provide secure, comfortable support during walks and activities. Up next, we’ll explore how to take accurate measurements to ensure the perfect fit.
Measuring Your Small Dog
Key Measurement Points
Getting the right harness fit for your dog starts with two main measurements: neck girth and chest girth. These ensure the harness is both comfortable and secure.
-
For neck girth, place a soft measuring tape where your dog’s collar naturally sits.
-
For chest girth, measure around the widest part of the ribcage, just behind the front legs.
"Dog harness products are designed around the comfort and safety of your pet, so measuring is going to help ensure that the product fits properly." - Jack Vandever, Chewy's senior manager of technical design for soft goods [5]
Keep in mind, weight alone isn’t enough to determine size. For example, a 20-pound Corgi and a 20-pound terrier will need different sizes due to their body shapes [7]. Similarly, a 40-pound Bulldog and a 40-pound Greyhound have very different builds and require distinct fits [8].
Measurement Best Practices
To get accurate results, follow these tips:
-
Use a soft measuring tape.
-
Measure while your dog is standing naturally.
-
Ensure the tape is snug but not tight - leave enough room for 1–2 fingers underneath.
If your dog is fidgety, try these tricks:
-
Measure after some exercise when they’re calmer.
-
Use a lick mat with peanut butter to keep them distracted.
-
Get a friend to lend a hand.
If your dog’s measurements fall between two sizes, go with the larger size for better comfort and safety [6].
Top Sizing Questions
Size Chart Guide: XS to M
Here's a quick guide to help you find the right harness size for your dog:
| Size | Chest (inches) | Common Breeds |
|---|---|---|
| XXS | 15–18 | Chihuahua, Puppy Dachshund, Puppy Whippet |
| XS | 18–21 | Dachshund, Maltese, Yorkshire Terrier |
| S | 21–24 | French Bulldog, Pug |
| M | 24–30 | Beagle, Standard Poodle |
Focus on your dog's actual chest measurements rather than relying solely on breed averages. Leave about 0.4–0.8 inches of extra space for comfort [9]. If your dog’s measurements fall between two sizes, use the chart as a guide and consider their body type for the best fit.
Sizing Between Two Options
When your dog is between sizes, their body shape plays a key role. Dogs with a slim frame might fit better in the smaller size, while those with a broader chest or more muscle should go for the larger one.
"If your dog is between sizes, we suggest going up a size." - Barc London [4]
Harness Style Size Differences
Harness style can also impact fit, so it’s worth considering how different designs work for your dog. For example:
-
Padded harnesses might require you to size up.
-
Adjustable designs provide more flexibility.
-
Front-clip options need precise chest measurements.
Some styles distribute pressure differently, which can be helpful for dogs with specific needs. Look for adjustable straps around the neck, chest, and belly to create a fit tailored to your dog’s shape [1].

Premium Materials and Design
The right materials and thoughtful design can make a huge difference in your dog's harness, offering both comfort and style.
Ultrasuede® Features
Harnesses made with Ultrasuede® stand out for their softness, durability, and easy maintenance. This material molds to your dog's body, providing a comfortable fit while withstanding everyday use.
"Handmade with the highest level of craftsmanship from premium Ultrasuede® offering unparalleled luxury, appeal, performance, and ease of care." [2]
"I love the material, it is super soft and forms nicely around the neck for a comfortable, flattering fit." – Nicole Cito [2]
Crystal Accents and Comfort
Some harnesses feature crystal embellishments for added elegance. These details are carefully placed away from sensitive areas, ensuring your dog stays comfortable while maintaining a secure fit.
Adjustable Fit Features
A good harness offers multiple adjustment points to suit your dog's unique shape. It should fit snugly but still allow you to slide two fingers underneath for the right balance of comfort and security [3].
A properly fitted harness won’t shift during movement, distributes pressure evenly, prevents chafing or hair loss, and keeps your dog from slipping out [3].
Check the fit regularly, as materials can stretch slightly over time. Adjust as needed to ensure your dog stays comfortable and secure.
Breed-Specific Size Guide
Finding the right harness for small dog breeds can be tricky due to their unique shapes and proportions. Here's a breakdown to help you choose the best fit.
Extra Small Breeds
For tiny breeds like Chihuahuas and Teacup Yorkshire Terriers, XX SMALL harnesses are ideal. These are designed for dogs weighing up to 5 lbs, with chest sizes between 8–10 inches.
Slightly larger breeds, such as standard Yorkshire Terriers and Toy Poodles, typically need X SMALL harnesses. These fit dogs weighing 5–10 lbs, with chest measurements ranging from 9–15 inches.
| Size | Weight Range | Chest Size | Recommended Leash Width |
|---|---|---|---|
| XX SMALL | Up to 5 lbs | 8–10" | 5/16" |
| X SMALL | 5–10 lbs | 9–15" | 3/8" |
Wide-Chest Breeds
Breeds like French Bulldogs and Pugs often need harnesses designed for their broader chests. These dogs typically have chest measurements around 21–24 inches. If your dog falls between sizes, it's better to go with the larger option to ensure a comfortable fit.
Long-Body Breeds
Long-bodied breeds require extra attention to harness length. The harness should stretch slightly beyond the body length while ensuring the metal rings align properly near the groin area.
For these breeds, a well-fitted harness should:
-
Allow a full range of motion without restricting the legs.
-
Evenly distribute pressure along the body.
-
Avoid limiting natural movement.
Checking Harness Fit
Signs of a Poor Fit
Making sure your dog's harness fits properly is key to their comfort and safety. Keep an eye out for these issues:
-
Chafing or Hair Loss: Look for irritation or bald spots where the harness touches your dog's skin.
-
Restricted Movement: If your dog seems uncomfortable or hesitant to walk, the harness might be limiting their movement.
-
Harness Rotation: The back piece should stay centered. If it keeps shifting, the fit might be off.
-
Loose Chest Strap: A chest strap that keeps loosening compromises the harness's security.
If you notice any of these problems, it's time to check the harness fit more closely.
How to Test the Fit
Use these simple methods to ensure the harness fits correctly:
-
Two-Finger Test: Slide two fingers under the harness. If it's too tight for two fingers or too loose for more than two, adjust accordingly.
-
Movement Check: Gently pull the harness backward and observe your dog's reaction. If they can slip out easily, it's not secure enough.
-
Activity Observation: Let your dog perform everyday actions like walking or sitting while wearing the harness. Watch for any signs of discomfort or restricted movement.
Keep It in Check
Fit can change over time, so make it a habit to test the harness regularly. Check it weekly and after events like washing, grooming, or noticeable growth. This helps prevent discomfort and ensures the harness stays effective.
Final Size Selection Tips
To ensure a perfect harness fit, start with precise measurements and keep a few key tips in mind. Focus on your dog's girth measurement, taken at the widest part of their chest (just behind the front legs). Use a cloth tape and measure this area three times for accuracy.
When deciding on a size, opt for the larger option if your dog is between sizes. Adjustable features allow you to create a snug yet comfortable fit. To double-check, slip two fingers between the harness and your dog's body.
"When sizing for a harness, you want to know the size of the chest, because that's what the harness is going around." - Melinda Rosato, Manager of The Hungry Puppy [10]
For puppies that are still growing, keep these tips in mind:
-
Add 2 inches to the chest measurement to allow for growth.
-
Choose harnesses with adjustable straps for extra flexibility.
-
Re-measure monthly during rapid growth phases.
If you're using premium Ultrasuede® harnesses, make sure the chest area fits smoothly. The fabric should lie flat against your dog's body without bunching or causing pressure points - especially around crystal embellishments.
Lastly, check the harness fit regularly, especially after grooming sessions or weight changes, to ensure your dog stays comfortable.
