This is the reference I was looking for. Unlike the Corgi rig I used, the dog in the reference video has longer legs, which allows me to better observe the movement of the legs.
However, corgis have short legs, a long body, and a distinctive movement pattern due to their proportions, which sets them apart from other quadrupeds
Short Legs: Corgis’ legs are much shorter relative to their body length. This results in a quicker, choppy gait compared to longer-legged breeds.
Long Body: Their extended torso moves slightly more than other dogs during walking or running, with a noticeable side-to-side sway.
Paw Positioning: Their paws land more under their body center due to their shorter legs and body structure, giving their walk a compact appearance
Lift and Swing: Corgi paws lift only slightly off the ground during movement. Avoid over-exaggerating the arc of the foot in the swing phase.
Placement: Their paws typically land in line with their body (not splayed outward) for stability.
Tail Dynamics: If the Corgi has a tail, include a subtle wagging or balancing motion that complements the gait.
So I also looked for reference videos of corgis walking online to achieve a more effective search
After that, I animated this locomotion
