I can't see how the "dog fang" can prevent chain suck. I use a dog fang on one bike to prevent "chain drop" - to stop the chain overshifting across the inner ring and landing on the bottom bracket.
Attaching a couple of cable ties to the chainstay and trimming the excess tie so that it hits the rising chain is the way to prevent chain suck - which is what I've used on my mountain bike. Also a rear mech with a clutch can help keep the chain from sucking to the ring.

Sorry Linus you are absolutely right .. my chain was dropping all the way off the triple and the design of the chainset was such that it got jammed. I got chain dropoff and chainsuck confused. My previous post is definitely "fake news" .. I will delete it off.
