LITE2 XS–L
A simpler, lighter ABUBA designed mainly for lighter dogs and everyday carrying
No Hip Belt · No Dog Back Support Cover
View LITE2For the parts of the day walking can't cover.
ABUBA4 is a dog carrier for longer outings, crowded places, travel days, stairs and the moments your dog needs a break.
Longer outings
Take the longer route.
For the trails, rides and city days that go further than a short walk.
Why it's built this way
Built around the way carrying actually works.
When a dog gets heavier, it matters where the load sits, how close the carrier stays to your body, and how both you and your dog are supported.
Fixed Wide Hip Belt
Helps share part of the load with the pelvis instead of relying on the shoulders alone.
Close-Body Fit
Keeps the carrier closer to you as you move.
Dog Back Support Cover
Supports your dog's back area.
Thicker Shoulder Padding
Adds cushioning where the shoulders still carry part of the load.
Neck Strap
Adjusts around the neck opening to help refine the fit.
Load distribution
Fit it so the load is shared.
Designed to redistribute part of the carrying load away from shoulder-only support and toward the pelvis.
Fit close
Adjust the carrier so your dog and the backpack sit close to your body.
Position the Hip Belt
Place the fixed wide Hip Belt securely around your pelvis. It stays fixed in place instead of clipping on, and is made wider for a more secure position.
Share the load
Let the shoulder straps and the hip belt work together, so the load is shared instead of carried by your shoulders alone.

How to measure
- Sitting Back Length: measure your dog's back length while your dog is sitting.

- Use a soft tape measure, not a metal one.
- If the two measurements point to different sizes, choose the larger size.
Sizing notes
Sizing rule: If the two measurements point to different sizes, choose the larger size.
Longer back length? If your dog's sitting back length runs about 5 cm longer than the standard fit for the size, consider EONG-KOO for a better fit.
ABUBA4 is built for dogs whose weight you can carry comfortably. It's a carrying system for movement, not a stationary rest spot.

FAQ
How do I choose my ABUBA4 size?
Measure your dog's Sitting Back Length and Chest Girth and compare them with the size chart. Choose size by these two measurements, not weight alone. If the two measurements point to different sizes, choose the larger size.
How does my dog sit inside ABUBA4?
Your dog isn't standing or hanging inside ABUBA4. They sit with their body folded much as it is when you hold them, leaning against you and the carrier.
What if my dog doesn't like the carrier at first?
Even a well-fitted carrier can feel unfamiliar at first. A short introduction period helps your dog get comfortable before longer carries. Walk your dog through it in five steps, at their own pace.
- Familiarize Let your dog see and sniff ABUBA4 before anything is worn.
- Put It On Put ABUBA4 on without expecting your dog to move in it yet.
- Adjust Fine-tune the straps and belt while your dog stands still.
- Reassure Reward calm behavior in short sessions before carrying.
- Carry Once your dog is comfortable wearing it, start with short carries.
Every dog adjusts at their own pace. These are things we observe, not proof of comfort.
Possible tension
- Gripping with claws
- Stiff front legs
- Excessive panting
- Ears pinned back
- Repeated attempts to get out
As your dog settles
- Paws relax
- Body tension decreases
- Breathing settles
- Leaning into the carrier
If your dog stays tense, go back a step and slow down.
When would I use ABUBA4?
ABUBA4 is for the parts of the day walking can't cover: longer outings, crowded places, travel days, stairs, cycling and the moments your dog needs a break, or when carrying in your arms or using a stroller isn't practical.
How is ABUBA4 different from LITE2 and MAX?
LITE2 is the simpler, lighter setup for shorter everyday use. It comes in XS–L and has no hip belt and no Dog Back Support Cover. ABUBA4 is the all-round model for longer outings and active use. It comes in S–XL and has a fixed wide hip belt, a Dog Back Support Cover and a built-in Wind Blanket. MAX is for larger and heavier dogs. It comes in 2XL–3XL with an extra-large hip belt, and the 3XL adds the Adjust System.
Does ABUBA4 have the Adjust System?
No. The Adjust System is exclusive to MAX 3XL.
Does the hip belt make a heavy dog feel light?
No. The fixed wide hip belt is designed to redistribute part of the carrying load away from shoulder-only support and toward the pelvis, so the shoulder straps and hip belt share the work. A larger dog is still a real load, so make sure you can comfortably carry your dog for the length of your outing.
How should the hip belt sit?
Place the fixed wide hip belt securely around your pelvis, with the carrier and your dog close to your body. Then adjust the shoulder straps so the carrier does not pull away from your back.
Can ABUBA4 be used for hiking or cycling?
Yes. ABUBA4 is the all-round ABUBA model for longer outings and active use, including hiking and cycling. Introduce it gradually first, following the steps under "What if my dog doesn't like the carrier at first?", and check that your dog is comfortable before longer carries.
Is ABUBA4 suitable for a 15 kg dog?
Weight alone can't answer that. ABUBA4 has no official weight range. Its size is decided by Sitting Back Length and Chest Girth, so measure both, check them against the size chart, and choose the larger size if they point to different sizes. If you are unsure, contact us and we will help.
The fit feels smaller than I expected.
The first time you use it, your dog may tense up or keep trying to stand, which can make the fit feel tighter. Carry your dog for about 7 minutes while gently patting them to settle down, then check the fit again.
What if ABUBA4 doesn't fit or work for my dog?
Contact our support team — they can help with sizing, fit, or a return.
