Aliasing pulling_collar → collar_pull
Link to alias

Reason:

Both tags seem to be for same thing. Suggest alias to collar_pull because similar tag leash_pull has wiki and 1766 posts.

(Seven tagged with pulling_collar .
19 tagged with collar_pull .)

Leash_pull wiki says "This is usually depicting a dominant character pulling the leash of a submissive character, but this can refer to any image depicting a leash being put under tension by another character."

Suggest collar_pull wiki say something similiar,
perhaps "Any image where a collar on one character is being pulled (or put under tension) by another character".
