A type of dog (cocker spaniel) bred to flush out game birds, or someone who coddles and indulges others.
From 'cock' (a rooster or game bird) which the spaniel was originally bred to hunt. The '-er' suffix indicates connection to this function.
Cocker spaniels have adorably long ears and sad eyes—and they became so popular in Victorian times that people started using 'cocker' as a verb meaning to spoil someone, because the dogs were so beloved!
