(if this has already been posted and I missed it sorry

It was late last night when a friend starting talking about a pet he couldn't call from his stable for long enough to actually feed/use mend pet on. "Scratches head"... I ask him what spec was he in and what pet was he trying to call ?
His reply made me sigh at first, 'SV and a Core Hound'..? But I said, that's not possible. Switch back to BM and you can use it, as corehounds are exotic! "But, I tamed it as SV!" he protests,

Well it seems I owe him an apology as indeed you can, I switched over to my alt lvl 80 hunter and flew over to MH to test it as MM.
Here's the proof...
The pet does indeed disappear as soon as it's tamed and you can briefly call it out before it vanishes again. So Blizz.....>!?!?!?
