Quick answer
An adult Miniature Dachshund usually measures 30–45 cm1 around the chest and weighs 4.5–5 kg2,3.
These are the sizes most adult Miniature Dachshunds need. Your dog may differ, so measure to be sure.
Get an exact size for your dogHow a Miniature Dachshund is built, and why it matters for fit
The UK breed standard gives Miniature Dachshunds an ideal weight of 4.5 kg, with a desired maximum of 5 kg2. That is less than half the 9–12 kg ideal for a Standard Dachshund3, so the two need very different harness sizes. See our Standard Dachshund guide if yours is a Standard.
Bailey & Coco puts the average Miniature Dachshund chest at 30–45 cm1. That's a big chest for a 5 kg dog, and it is why weight alone is a poor guide for this breed.
Like Standards, Minis are long in the body with low ground clearance, so the strap behind the front legs sits close to the ground, and vest-style harnesses made for short-backed dogs can end halfway along the body.
How to measure your Miniature 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 legs4. 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 up5.
- 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 twice4. 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 guide5; the other brands here size by chest only.
Miniature Dachshund measuring tips
- Measure the deepest part of the chest behind the front legs, keeping the tape level with the ground.
- Measure the base of the neck too. A Mini's neck is much smaller than its chest, so look for a harness where the two adjust separately.
- Julius-K9 measures two finger-widths behind the front legs for its Baby sizes and three for Mini-Mini5, which is where most Minis fall.

Miniature 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 Miniature Dachshund fits each chart, and why.
Julius-K9
IDC Powerharness
Julius-K9 lists a chest range and a weight range for every size5. Chest girth is the main guide; we use weight to choose between two sizes when the chest fits both.
- A smaller Miniature Dachshund (chest 30 cm, 4.5 kg): size Baby 1
- A typical Miniature Dachshund (chest 37.5 cm, 5 kg): size Baby 2
- A larger Miniature Dachshund (chest 45 cm, 5 kg): size Mini-Mini (also fits Baby 2)
Overlaps in the Miniature Dachshund range: 33–36 cm: sizes Baby 1 and Baby 2 both fit; 40–45 cm: sizes Baby 2 and Mini-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 |

Small dogs reach adult weight sooner than large breeds8. A Mini puppy may go through several harness sizes in its first months, then settle.
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 kg8. An adult Miniature Dachshund at 4.5–5 kg falls in the under 6.5 kg group.
Size a puppy on its chest measurement today, not on the size you expect it to reach4. 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 Miniature 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 Miniature Dachshund:
- Julius-K9: 33–36 cm: sizes Baby 1 and Baby 2 both fit; 40–45 cm: sizes Baby 2 and Mini-Mini both fit.
- Ruffwear: no overlapping sizes in this range.
- Bailey & Coco: 30–41 cm: sizes XXS and XS both fit; 35–45 cm: sizes XS and S both fit; 40–45 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 size6. For a growing puppy that is truly between sizes, Ruffwear also suggests the larger one4.
- For Julius-K9, check the weight ranges too: if your dog's weight only fits one of the two sizes, go with that one5.
- 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 more6. 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 forward9, 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 Miniature Dachshund
Y-front harness with an adjustable chest piece
Lets the front sit beside the breastbone rather than pressing on it.
Step-in harness
Easy to put on a small, low dog without lifting it or pulling anything over its head.
Separately adjustable neck and chest
Copes with the big difference between a Mini's neck and chest.
Be careful with
- Vest harnesses that are too short in the back.
- Using a harness handle to lift your Dachshund. If you're not sure how best to pick your dog up, ask your vet.
Common mistakes
- Using Standard Dachshund sizes for a Mini.
- Choosing by weight. A 5 kg Mini can have a chest as big as a much heavier dog of another breed.
- Assuming a harness protects the back. UK Dachshund health groups say the evidence doesn't show that (see below).
- 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 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 problems10. One survey found dogs walked on harnesses were more often affected, though many owners had switched to a harness after their dog's back problem, which affects that comparison11. If your Miniature Dachshund has had a neck disc problem, ask your vet whether a harness or a collar suits it better10.
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 it12. Many owners clip the lead to the harness and use the collar for ID.
Miniature Dachshund harness questions
What size harness does a Miniature Dachshund need?
An adult Miniature Dachshund usually has a chest of 30–45 cm and weighs 4.5–5 kg2,3. That usually means Julius-K9 IDC Powerharness: sizes Baby 1 to Mini-Mini; Ruffwear Front Range Harness: sizes XXS or XS; Bailey & Coco Trail & Glow Harness: sizes XXS to S. Measure your dog's chest to get the exact size.
How do I measure my Miniature Dachshund for a harness?
Stand your dog square, then wrap a soft tape around the widest part of the chest just behind the front legs4. 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 Miniature Dachshund puppy?
Size a puppy on its chest measurement today, not its expected adult size4. 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 Miniature Dachshund is between two harness sizes?
Is a harness or a collar better for a Miniature Dachshund's back?
Do Miniature and Standard Dachshunds take the same harness?
Does a Miniature Dachshund still need a collar?
Many owners use both. A harness keeps pressure off the neck on walks, but in the UK a dog in a public place must wear a collar with the owner's name and address on it or on a tag12.
