Dr. Herder

Dr. Lowell Herder is a pediatrician who appears in the fourth season Dinosaurs episode "Terrible Twos." His face was played by David Greenaway, his body was puppeteered by Tom Fisher and his voice was provided by Michael McKean. The Sinclairs seek the doctor's help when Baby Sinclair turns two. Earl requests a sedative, but while the physician can dispense dangerous drugs at will, he chooses not to in this instance. Following the examination, Dr. Herder instead recommends setting concrete bounadries, specifically by walling the child inside a cave for a year.
