Inland Croaker

I disagree with some of the comments here, this isn't a useful pet for PVP. Blizzard isn't a very powerful weather effect, and aquatic pets are just bad in general. If you want Blizzard, look elsewhere. Christmas pets are better than this guy, I think.

A P/P with Ice Tomb- Frost Nova - Ice Lance combo is devastating. Nukes, Roots and stuns the oppositions preventing swap outs. The Ice Lance hits a 150% extra when stunned.

I'm having fun with a team of three of these in PVE.

Extraordinarily strong against Mech pets and a muts have (P/P) for anyone still doing the Draenor Masters (see the Cymre Brightblade strat on XuFu's site). I think this is a vastly underrated pet.

Replying to Viline's comment regarding cold weather frogs. There's one that survives the Arctic Circle. Could be what this frog was based on:

Wood Frog

The wood frog ( Lithobates sylvatica ) is one species of terrestrial frog that has adapted to survive cold winters. This species is found in Canada and Alaska. During the winter, up to 45 percent of the frog's body actually freezes. The frog spends a few months in this state before thawing out in the spring.

Suggestions on the best breed for PVP or PVE - Dungeons?

Good breeds, and good abilities make for a solid battle pet. A bit odd having a frog enjoy cold weather, but to each their own. Good synergy with its own abilities, as well as other chill related pets. A rooting nightmare in pvp.

Just south of Boralus along the coast you can find many who join the battle with other pets.

Sticky Goo is broken at the moment. The talent will not do anything. It doesn't cast or do anything yet it counts as if you did cast something. Openning a ticket.

You can find a few of them easily in the Hatherford river in northern Tiragarde Sound
