I have an addon that does this for all previous content pets. (I think it's Pet Tracker, but I have several other pet addons, so I might be wrong.)
In the info window of the pet journal, when I click on a pet, it says something like
Available: (list of every possible breed this pet could be)
This helps me to know whether I already have the breed that I want, or if it comes in a breed I'd like better and I should keep hunting.
WoD pets tell me what breed they are, but not all possible breeds they could be.
Tried Battle Pet BreedID - it does not do this, and can't seem to find the info I'm looking for anywhere.
Could anyone here point me to such a list? Could be for an addon that would tell me, or an out of game list for reference, either would be great. I'd really appreciate it!
(Hope this makes sense; had wrist surgery last week and have to type with one hand for now, which puts a new premium on brevity!)
