pup

This term evokes a sense of vulnerability and playfulness, typically associated with the early stages of canine or pinniped development. It is more informal and affectionate than the technical term puppy, though in the context of seals or otters, it is the standard biological designation.

When used as a verb, the word describes the biological process of whelping. This usage is primarily restricted to veterinary or breeding contexts and is rarely encountered in casual conversation.
