/cast Freezing Trap(Rank 3)
/script PetFollow(); PetPassiveMode(); ClearTarget();
/cast Feign Death

Spam that macro and you will FD insta trap

/script if UnitAffectingCombat("player") then CastSpellByName("Feign Death"); PetFollow(); PetPassiveMode();else CastSpellByName("Freezing Trap");end
Another good macro. If you're out of combat - you'll just place a Freezing Trap. Otherwise - you will use FD+Freezing Trap and cancel your pet's next attack preventing him from trap breaking.
