How to Measure a Dachshund for a Harness (Size Guide for the Perfect Fit)
If you’re wondering how to measure a dachshund for a harness, you’re in the right place.
Dachshunds are not shaped like other dogs.
They’re long.
They’re deep-chested.
They’re low to the ground.
And that means proper measurement is essential when choosing a harness.
A poor fit can cause:
- Rubbing under the arms
- Slipping out during walks
- Pressure on the spine
- Discomfort or restricted movement
Let’s walk through exactly how to measure your dachshund for the perfect harness fit.
Why Proper Harness Sizing Matters for Dachshunds
Because dachshunds are prone to back issues like IVDD, pressure distribution is important.
A properly fitted harness should:
- Sit securely at the chest
- Avoid the throat and mid-spine
- Stay centered when walking
- Allow full shoulder movement
Before ordering any adjustable harness, accurate measurements are step one.
What You’ll Need
- A soft measuring tape (tailor’s tape works best)
- Your dachshund
- Treats (very important)
If you don’t have a soft tape, you can use string and measure it against a ruler afterward.
Step 1: Measure Chest Girth (Most Important Measurement)
The chest girth is the most critical measurement when sizing a dachshund harness.
How to measure chest girth:
- Stand your dachshund on all four legs.
- Wrap the measuring tape around the widest part of the chest.
- This is usually right behind the front legs.
- Make sure the tape is snug but not tight.
- You should be able to slide one finger under the tape.
Write this number down.
For most harnesses — including adjustable styles — chest girth determines the size.
Step 2: Measure Neck Circumference
While chest girth is primary, neck measurement helps ensure the harness doesn’t gap.
How to measure neck:
- Wrap the tape around the base of the neck.
- Measure where a harness would naturally sit — not high like a collar.
- Keep it snug but comfortable.
This helps ensure proper balance and support.
How a Properly Fitted Harness Should Look
After adjusting your harness:
✔ It should sit at the chest, not the throat AND the logo should be on the front of the chest with the straps on the back along the spine
✔ It should not rub under the armpits
✔ It should stay centered during movement
✔ You should be able to fit two fingers between harness and body
✔ It should not shift toward the mid-back
If your dachshund can back out of it, it’s too loose.
If they look restricted or stiff when walking, it’s too tight.
Common Dachshund Harness Sizing Mistakes
Guessing Based on Weight
Weight alone doesn’t determine harness size.
Two 15 lb dachshunds can have completely different chest measurements.
Buying “Small Dog” Without Measuring
Dachshunds are not shaped like other small breeds.
Always measure chest girth.
Ignoring Adjustability
An adjustable harness is ideal for dachshunds because their proportions vary so much.

What If Your Dachshund Is Between Sizes?
If your dog falls between two sizes:
- Choose the size that best matches chest girth
- Ensure there is room to tighten straps
- Avoid choosing a size that is too small and maxed out
Adjustability is key for a secure fit.
Final Thoughts: Measure Once, Walk Confidently
Taking 60 seconds to measure your dachshund can prevent:
- Returns
- Poor fit
- Spinal strain
- Escapes during walks
Because when it comes to long backs and big personalities, precision matters.

Your wiener deserves a harness that actually fits their body.
