Random Riddle: Fusing Words

Each statement describes two words that when fused together create a new unrelated word (not a compound word). The clues do not necessarily indicate in which order the two words are attached.

Example: This is the oldness of a tablet (pill + age = pillage).

1) This is a canine’s mother.
2) This is currently not there.
3) This is when pain is required.
4) This is a long time for a boar.
