Well you cannot have the best of both worlds, before the guards attacked anything that moved and now they dont attack pets at all - which in my eyes is good to be honest. Im afraid the TAO's will have to level there pets the old fashioned way. I know what your going to say - to level your skill the thing needs to die many times correct !!! Well Tele to say Prajna as a example and let the ronins kill him (which they will) - only way i can think of, using the guards was not meant to be the case in mir2/3 etc and people just used this method to quickly level there skills when im sure your supposed to just use it and as it dies, it slowly levels..
