Question about enchanter pet XP rules

[mickmoranis]

I am pretty sure this is true but Im not 100% sure..

If you have a pet that is at 70% fighting a mob that is at 10%

can you break the pet, mez the pet, kill the mob with DD and obtain 100%xp, then re-charm your pet?

Or do you have to kill the pet or anything?

Is it as long as you dont have the pet under your control while the mob dies, does it wipe the 50% xp the pet would have taken had you just let it kill the mob?
