Why ABUBA4
So the Walk Doesn't Have to End.
ABUBA4 took 1 year and 2 months to develop, built around one question: what does a dog actually need when walking on its own isn't an option?
4 Core Features
Built Around Four Changes
01
A Belt That Stays Put
Unlike a belt you clip on only when needed, ABUBA4's waist belt stays fixed in place. Helps distribute up to 70% of the carrying load through the waist belt.
02
Weather Built In, Not Bolted On
A Wind Blanket is already part of ABUBA4 — close it around your dog for wind, rain, or cold, with nothing extra to attach before you head out.
03
Thicker Where It Counts
Shoulder padding is twice as thick as the previous design for added cushioning.
04
Room for the Rest of the Outing
Expanded storage gives you more room for everyday essentials.

FAQ
Questions Before You Buy
Answers to what people ask most before ordering ABUBA4.
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.
How do I pick the right size?
Measure your dog's sitting back length and chest circumference. If the two measurements point to different sizes, choose the larger size.
What if ABUBA4 doesn't fit or work for my dog?
Contact our support team — they can help with sizing, fit, or a return.
