Pet abilitiesFollow

hi i read on the forum of worldofwarcraft.com and there was a post mentioning that beats tamed with the taming rod at lv 10 get to keep their original abilities while the ones we tame by spell do not. can anyone confirm this statement? for example an ice claw bear can ice claw, while a boar can charge but the ones we tame with spells do not have these abilities. is it worth it to raise another hunter and keep the pet we tamed with a rod?... any comments will be fully respected and appreciated, thanks in advance!
