I dont think that was the question, and I believe that the answer is presently "no", if you remane your pet, you will be unable to see the evolution prefixes for it, and any subsequent pet.
Thing is if you don't rename it, it might get confused if there is more than one ranger with the same type of pet. Anet should fix this. I managed to figure out my pet's evolution though it was far from straightforward - Elder Melandru Stalker
