The published belt is the useful starting point
The indexed Amazon US listing identifies XMKEY, the target ASIN, a motor advertised at 2.5 horsepower and manual incline. It explicitly describes the running belt as 41.37 inches long and 15.76 inches wide. Its overall frame measures 51.22 inches long, 22.06 inches wide and 27.58 inches high in the same specification extract.
This guide uses a descriptive 41-inch-belt name because a consistent formal model number was not established. Keep B0GTPVXV3V with the measurements when comparing listings. If a page changes its selected variation, check that its dimensions still match before relying on the photograph, product title or specifications.
How it differs from the compact GP22-1
The compact GP22-1 listing has a published overall length of 44.33 inches, while this machine lists 51.22 inches. That frame difference supports treating them as separate products rather than assuming they are color options. The running belt on the GP22-1 remains unconfirmed, so the available evidence does not support a precise belt-length advantage between them.
A larger frame can be useful only if the usable running space suits the dog and the room can accommodate the equipment. Compare this model’s stated belt with your dog’s moving stride and body dimensions. The usable area is the relevant measurement for movement; the overall frame is the relevant starting point for a floor plan.

Check incline and electric controls
Manual incline means you should understand how the slope is changed and secured. Ask the seller for those steps and confirm when the instructions permit adjustment. Do not assume the treadmill changes incline automatically during a preset program merely because both incline and programs appear in the listing.
The US offer describes a 0.5–6-mile-per-hour range and 12 programs. Treat that range as a specification to confirm in the supplied manual, not a recommended pace for your dog. Ask about speed increments, program changes and how to stop a session. A maximum-speed headline says little about how convenient the controls will be during a careful introduction.
A practical purchase decision
This XMKEY is easier to compare on paper than listings that omit their usable belt dimensions. That transparency is useful, but it does not establish running stability, stopping performance or noise. We have not measured those properties, and the advertised load capacity alone cannot establish whether a dog has enough stride room.
Before ordering, verify the selected ASIN and request the current manual. Mark out the frame with room for entry, observation and control access. Ask about replacement belts, maintenance requirements and return packaging. Choose it when its documented running area and controls match your needs, rather than choosing it simply because its title includes a larger capacity or more features.
