I am trying to generate a rig for this dog mesh using Blenders rigify cat rig (I heard there are some bugs with Rigify's dog rig) however I ran across this error "RIGIFY ERROR: Bone 'spine': Input to rig type must be a chain of 3 or more bones. Incorrect armature for type 'chain_rigs'" when clicking the generate rig button in Object Data Properties.
Alongside the error message an extra bone appears, labeled ORG-pelvis.C I thought one of my bones might not be attached correctly so I checked "connected" in every bones properties but still had no luck. I also tried to snap all the children bones to their parents by using snap cursor to selection on the parent bone and then, snap selection to cursor on the child bone but I still encounter this error.
Any help would be appreciated. Thanks!
