Dogs see better than humans in dim light because of a reflective layer called the tapetum lucidum.

Is it true that dogs see better than humans in dim light because of a reflective layer called the tapetum lucidum?

Unclear. The retrieved sources partially support the claim: one reference states the tapetum lucidum enables animals to see in dimmer light, another confirms dogs possess this reflective tissue, and a Skeptics answer says dogs excel at night vision. None of the placed items directly compares dogs' dim-light vision to humans' or ties that advantage specifically to the tapetum lucidum.
