Quick answer
An adult Standard Dachshund usually measures 35–50 cm around the chest and weighs 7–14 kg1.
These are the sizes most adult Standard Dachshunds need. Your dog may differ, so measure to be sure.
Get an exact size for your dogHow a Standard Dachshund is built, and why it matters for fit
Breed standards describe a strong, prominent breastbone with a small dip on either side of it, and a deep, oval ribcage that reaches down to about the middle of the forearm2. In other words, the chest is very deep for such a short-legged dog, and the breastbone sticks out in front.
That creates three fitting problems. The chest girth is large for the dog's height. The strap behind the front legs sits close to the ground. And the long back means vest-style harnesses made for short-backed dogs can end halfway along the body or press on the breastbone.
This guide covers Standard Dachshunds (7–14 kg). Miniature Dachshunds are a separate, smaller size and usually need smaller harness sizes, so measure your dog.
How to measure your Standard Dachshund, step by step
- Get a soft tape measure, or a piece of string and a ruler. Stand your dog on a level floor with all four feet square underneath it.
- Find the measuring point: the widest part of the ribcage, just behind the front legs3. Julius-K9 asks you to measure a set distance behind the front legs, which depends on the size: two finger-widths for the Baby sizes, three for Mini-Mini and Mini, and four for size 0 and up4.
- Wrap the tape all the way round. Keep it flat and untwisted, snug against the body but not squeezing. Read the number in centimetres where the end meets the tape.
- Measure twice3. If the two readings differ, use the larger one.
- Weigh your dog too. Julius-K9 gives a weight range for every size as a second guide4; the other brands here size by chest only.
Standard Dachshund measuring tips
- Measure the deepest part of the chest behind the front legs. Keep the tape level with the ground; on a long, low dog it's easy to measure at a slant.
- Also measure the length from the base of the neck to the base of the tail if you are looking at a vest-style harness, so you can check it isn't too short or too long.
- Measure the neck at its base, too. Dachshunds often need a harness with an adjustable neck opening because the neck and chest sizes differ a lot.

Standard Dachshund harness size by brand
Each brand cuts its sizes differently, so the same dog can be a different size, or a different letter, in each. Here is how a typical adult Standard Dachshund fits each chart, and why.
Julius-K9
IDC Powerharness
Julius-K9 lists a chest range and a weight range for every size4. Chest girth is the main guide; we use weight to choose between two sizes when the chest fits both.
- A smaller Standard Dachshund (chest 35 cm, 7 kg): size Baby 2 (also fits Baby 1)
- A typical Standard Dachshund (chest 42.5 cm, 10.5 kg): size Baby 2 (also fits Mini-Mini)
- A larger Standard Dachshund (chest 50 cm, 14 kg): size Mini (also fits Mini-Mini)
Overlaps in the Standard Dachshund range: 35–36 cm: sizes Baby 1 and Baby 2 both fit; 40–45 cm: sizes Baby 2 and Mini-Mini both fit; 49–50 cm: sizes Mini-Mini and Mini both fit.
Sizes overlap by design; chest girth is the main guide, weight is secondary.
| Size | Chest | Weight |
|---|---|---|
| Baby 1 | 29–36 cm | 0.8–3 kg |
| Baby 2 | 33–45 cm | 2–5 kg |
| Mini-Mini | 40–53 cm | 4–7 kg |
| Mini | 49–67 cm | 7–15 kg |
| 0 | 58–76 cm | 14–25 kg |
| 1 | 63–85 cm | 23–30 kg |
| 2 | 71–96 cm | 28–40 kg |
| 3 | 82–115 cm | 40–70 kg |
| 4 | 96–138 cm | 70–90 kg |

Standard Dachshunds are medium-weight dogs on short legs, and smaller dogs reach adult weight sooner than large breeds7. The chest keeps deepening as they mature, so keep re-measuring through the first year.
The largest study of puppy growth so far, based on records from over 6 million young dogs, grouped dogs by adult weight: under 6.5 kg, 6.5–9, 9–15, 15–30 and 30–40 kg7. An adult Standard Dachshund at 7–14 kg falls in the 6.5–9 kg and 9–15 kg groups.
Size a puppy on its chest measurement today, not on the size you expect it to reach3. A harness bought to "grow into" is loose now, and a loose harness slips, rubs and is easier to back out of.
While your puppy is growing fast, we suggest measuring its chest every two weeks, then monthly until it stops changing. A quick check in between: if you can no longer slide two fingers under the straps, measure again.
Most harnesses adjust over a good part of their range, so a growing puppy may stay in one size for a while. When your puppy's chest reaches the top of its size's range, move up.
If your Standard Dachshund is between two sizes
Brand charts often overlap, so a chest measurement can fall inside two sizes. Here is where that happens for a typical adult Standard Dachshund:
- Julius-K9: 35–36 cm: sizes Baby 1 and Baby 2 both fit; 40–45 cm: sizes Baby 2 and Mini-Mini both fit; 49–50 cm: sizes Mini-Mini and Mini both fit.
- Ruffwear: no overlapping sizes in this range.
- Bailey & Coco: 35–41 cm: sizes XXS and XS both fit; 35–50 cm: sizes XS and S both fit; 40–50 cm: sizes S and M both fit.
How to choose:
- Our size finder picks the size where your dog's measurement sits nearer the middle of the range, so the harness can be adjusted either way.
- Ruffwear says that if your dog is right on the border between two sizes and fully grown, choose the larger size5. For a growing puppy that is truly between sizes, Ruffwear also suggests the larger one3.
- For Julius-K9, check the weight ranges too: if your dog's weight only fits one of the two sizes, go with that one4.
- Deep-chested dogs with a narrow waist can slip a loose harness, so if the larger size would only just fit on its tightest setting, the smaller one is usually safer.
Fit checks when the harness arrives
Two-finger rule
You should be able to slide two fingers flat under every strap, and no more5. Tighter than that can rub; looser can slip.
Strap behind the front legs
The strap around the body should sit a little way behind the front legs, not pressed up into the "armpit", where it will rub as your dog walks.
Nothing on the throat
Every strap at the front should sit on the breastbone or low on the chest, not across the throat.
Free shoulders
Watch your dog walk and trot. Its stride should look the same as without the harness. A small study found harnesses can shorten how far the shoulder reaches forward8, so if the stride looks shorter, adjust the fit or try another style.
Check for rubbing
After the first few walks, look behind the front legs, under the chest and around the neck for redness or broken hairs. If you find any, loosen or reposition the harness. If the skin is sore, stop using it and ask your vet.
Escape test
With the harness on, gently pull the lead forwards, then backwards and upwards. The harness shouldn't slide over the shoulders or ribs. If it does, tighten it, or choose a design with an extra strap behind the ribcage.
Re-check after a week
Webbing and buckles can settle in the first few walks. Check the two-finger fit again after a week.
Harness styles that suit a Standard Dachshund
Y-front harness with an adjustable chest piece
Lets the front strap sit on either side of the prominent breastbone instead of pressing on it.
Step-in harness
Easy to fit on a short-legged dog without lifting it or pulling anything over its head.
Harness designed for long-backed dogs
Some brands make harnesses with a longer back section for dogs of this shape.
Be careful with
- Vest harnesses that are too short in the back or press on the breastbone.
- Using a harness handle to lift your Dachshund off the ground. Lifting by the middle leaves the front and back unsupported. If you're not sure how best to pick your dog up, ask your vet.
Common mistakes
- Assuming a harness protects the back. UK Dachshund health groups say the evidence doesn't show that (see below).
- Buying a small-dog size because the dog is short. The deep chest often needs a bigger size than its height suggests.
- Measuring at a slant instead of straight around the deepest part of the chest.
- Measuring the neck instead of the chest. Harness sizes are set by chest girth.
- Assuming a size letter means the same thing in every brand. A Medium in one brand can be a Large in another, so check each chart in centimetres.
- Buying a size up "to grow into" for a puppy.
A note on health
The UK Dachshund health groups say that most Dachshund disc problems happen in the middle and lower back, not the neck, so walking a Dachshund on a collar is unlikely to increase its risk of back problems9. One survey even found dogs walked on harnesses were more often affected than dogs walked on collars, though many owners had switched to a harness after their dog's back problem, which affects that comparison10. If your Dachshund has had a neck disc problem, ask your vet whether a harness or a collar is better for your dog9.
Collar and ID tag: the UK rule
In the UK, a harness doesn't replace a collar. A dog in a public place must wear a collar with the owner's name and address on it, or on a tag or plate attached to it11. Many owners clip the lead to the harness and use the collar for ID.
Standard Dachshund harness questions
What size harness does a Standard Dachshund need?
An adult Standard Dachshund usually has a chest of 35–50 cm and weighs 7–14 kg1. That usually means Julius-K9 IDC Powerharness: sizes Baby 2 to Mini; Ruffwear Front Range Harness: sizes XXS or XS; Bailey & Coco Trail & Glow Harness: sizes XS or S. Measure your dog's chest to get the exact size.
How do I measure my Standard Dachshund for a harness?
Stand your dog square, then wrap a soft tape around the widest part of the chest just behind the front legs3. Keep it flat and snug and read it in centimetres. Measure twice. See our full guide to measuring your dog.
What size harness for a Standard Dachshund puppy?
Size a puppy on its chest measurement today, not its expected adult size3. Measure every couple of weeks while it grows fast and move up a size when its chest reaches the top of the current size.
What if my Standard Dachshund is between two harness sizes?
Is a harness or a collar better for a Dachshund's back?
UK Dachshund health groups say most disc problems in the breed happen in the middle and lower back, so a collar is unlikely to add to the risk, and there's no clear evidence that a harness protects the back910. Choose whichever your dog walks comfortably in. If your dog has had a back or neck problem, ask your vet.
Do Standard and Miniature Dachshunds take the same harness size?
No. Miniatures are much smaller, so they usually need smaller sizes. This guide is for Standards. For a Miniature, measure the chest and use the size finder with your own measurement.
Why don't normal harnesses fit my Dachshund?
Because of the shape: a deep chest, a prominent breastbone and a long back. Look for a harness with a separately adjustable neck and chest, and a front that sits beside the breastbone rather than on it.
