'''Cretins''' may be recognised as '''disproportionate dwarfs''' with a broad skull, a short mandible, short and thickened legs and an ataxic gait. These signs occur because thyroid hormones are needed for normal osteogenesis and endochondral ossification. Affected animals should be differentiated from proportionate dwarfs suffering from congenital panhypopituitarism or other causes of stunting. | '''Cretins''' may be recognised as '''disproportionate dwarfs''' with a broad skull, a short mandible, short and thickened legs and an ataxic gait.
