Take pets for a walk (4)

I believe the answer is:

step

I'm a little stuck... Click here to teach me more about this clue!

'for a walk' is the definition.
(I've seen this before)

'take pets' is the wordplay.
'pets' anagrams to 'STEP'.
But, I am not sure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for step that I've seen before include "Put foot on a pest" , "Pace for a pest" , "Pace (taken one at a time?)" , "bit of a dance" , "Stride" .)

I've seen this clue in the Evening Standard.
