Get canines, for example, (alien hounds initially) in golfer’s resting place (6)
I believe the answer is:
teethe
'get canines for example' is the definition.
'alien hounds initially in golfer's resting place' is the wordplay.
'alien' becomes 'et' (extra terrestrial).
'initially' suggests taking the first letters.
'in' indicates putting letters inside.
'golfer's resting place' becomes 'tee' (where a golfer rests a ball before hitting it).
The first letter of 'hounds' is 'h'.
'et'+'h'='eth'
'eth' put within 'tee' is 'TEETHE'.
(Other definitions for teethe that I've seen before include "suffer in early youth" , "Experience growing pains" , "Of baby, having first gum growth" , "Cut one's first choppers" , "Cut one's milk teeth" .)
