The bulk update request #9358 is pending approval.
create implication prong_collar (12) -> chain_collar (446)
create implication prong_collar (12) -> slip_collar (2)
create implication choke_chain (30) -> chain_collar (446)
create implication choke_chain (30) -> slip_collar (2)
Reason: Prong collars and choke chains are types of chain collars.
Slip_collar isn't currently a tag, however I feel it should be. It's a term used for collars that have a tightening action when pulled. Prongs are a type of martingale or limited-slip collar which means they have a limit to how tight they can be pulled. Slip collars aren't exclusively chain.
Also I plan on shortening the prong wiki. It has incorrect information and the ethics and legality of use aren't relevant here.
