Bumping with info from the WoWDB PTR pages...
Bernard:
Avalanche (4t), Bark, Bite, Call The Pack (3t), The Good Stuff (4t), Tough n' Cuddly (4t)
Mostly beast attacks, whilst Avalanche is an elemental one that hits all enemy pets. I'm guessing it'll be something like this (2/15 & 4/20 may be reversed):
L1/10: Bark / Bite - basic no-CD attacks
L2/15: Call The Pack / Avalanche - heavy hitters
L4/20: The Good Stuff / Tough n' Cuddly - defensive abilities
Note that Call The Pack has a 3 turn CD, but I'm guessing is meant to continue for 3 rounds like most swarm abilities (could be like Spiderling Swarm I guess, though unlike that it doesn't deal bonus damage to webbed enemies).
Murkalot
Blessed Hammer, Falling Murloc, Lash, Reflective Shield (3t), Righteous Inspiration (5t), Shieldstorm (8t)
In brief, a mix of humanoid and magic abilities, including a magic attack (Blessed Hammer). Maybe something like:
L1/10: Blessed Hammer / Lash
L2/15: Falling Murloc / Reflective Shield
L4/20: Righteous Inspiration / Shieldstorm
Note also that Blessed Hammer's power in the WoWDB tooltip is 7, but the datamined tooltip says 21 - possibly it's designed to be split amongst all enemy pets?
Apologies for the lack of links, but this limit on external links for low-post-count people is... irritating

. Suffice to say, the WoWDB PTR pages for both pets have plenty of details, although not the levels at which each ability is learned.
