Is it true that dogs vary far more in body size and shape than domestic cats do?
Unclear. Two peer-reviewed items partially support the claim: one reports that dogs have significantly larger and more variable frontal sinus morphology than cats, and another shows domestic dogs vary widely in body mass and limb bone morphology. Neither item directly compares the overall range of body size and shape variation between dogs and cats.
