I know what they do, the description does a good job describing that. What I dont understand (with the exception of the agg/deff trimmer) is how they work / when they work and how long they work for. IE: The aggressive one that makes your pets hits "taunts" ... how long does that last after I use it? DO I need to use it every few seconds, once a fight etc. etc etc. I cant seem to find the answer I am looking for.
