Armor that gives Pets Potion Effects

 Hi, I am trying to make a private mod for a YouTube SMP that I am creating at Giga Entertainment. I want to make custom armors that allow for specific class progression to the build. One of my co-workers wanted to be a beast master. My idea for this progression system was to make armor that, when applied to the armor slots, would give strength to any mob he had tamed. For the example of this post, I am using a wolf and I tried to give you the If then do command. I want to be able to make the command myself, but I am not familiar with coding all that well. My question is what kind of layout do I need in order to make this?
