The new Perky Pug pet has been confirmed by Blizzard to be a reward for using the upcoming Dungeon System (which will replace Looking For Group). Most likely it will be awarded for completing heroic dungeons with a total of 100 other random players.
Players who take part in groups who have one or more members who have been matched with them randomly from within the Dungeon System will receive extra rewards, up to and including the coveted Perky Pug non-combat pet. The more random players with whom one groups, the faster the pet can be obtained.

It looks like the Disgusting Oozeling is getting a friend in patch 3.3. According to MMO Champion, the newest PTR build brings us this carcinogenic companion:
Toxic Wasteling - Right Click to summon and dismiss your toxic wasteling. Do not feed toxic wasteling. Do not allow toxic wasteling to approach small animals. Do not touch, sniff, or even look at toxic wasteling for extended periods of time.
We still have no idea how this pestilent pet will be obtained (or what the in-game consequences may be for having him out), but we'll keep you posted.
The Raptor Hatchlings that drop from rare spawns will become ground spawns in rare raptor nests. No more afk camping with the NPCScan addon.
Hatchlings: Leaping, Darting, Razormaw, and Ravasaur Hatchlings no longer drop from their associated rare creatures. Instead, there are now rare nests that spawn which contain these hatchlings. For example, the Leaping Hatchling can now be found in Takk’s Nest rather than as a drop from Takk the Leaper.
Additionally, Blizzard is working on implementing a method of transferring Bind on Account items between Horde and Alliance. They hope to have it ready for patch 3.3. This means you'll be able to freely transfer any BoA pets between all of your characters. Yay, now my moo cow can get a Tyrael!
Remember Pengu the slightly satanic-looking pet penguin that you can buy after reaching exalted with the Kalu'ak? Apparently he's getting exorcised in Patch 3.3. His current look on the PTR shows bright blue eyes instead of creepy glowing red.
New reports from MMO Champion reveal a possible new pet data mined from the most recent PTR build: Perky Pug. Many people have speculated that this pet will be the reward for the highest tier achievement for the new cross-server Looking For Group system.
This pup is an exciting prospect because it means we might finally be getting pet doggies! Our first hint that such canine companions might be coming was in the Gilneas preview which shows a Mastiff dog.
Calico Cat & Albino Snake
Patch 3.3 just hit the PTR and it includes some new pets! Breanni, our beloved pet supplies vendor of Dalaran, will be stocking two new pets: Albino Snake and Calico Cat. As you might guess by its name, the snake is white with red eyes. The cat (pictured) is mostly black with some orange patches and a white belly. Each sells for 50g (40g with discount) and is available in unlimited supply.
Just how Breanni can stock so many of these new and exciting pets, nobody knows! I suspect that she is secretly a master geneticist. Either that or she got a bright idea when her Bombay got into the bleach and orange dye.
Vanity Pet Achievement
A new special vanity pets tracking achievement was data mined from the 3.3 PTR. It tracks several of the rarer pets including whelplings, raptor hatchlings, crocolisks and more. We can only hope that this achievement will eventually be implemented and that it will reward a super duper, fantabulous, cuddly wuddly, awesome pet reward. And by that I mean a green or orange baby murloc.
