Lastly, there was a Clonetrooper named Wolffe and Plo Koon's squad were nicknamed the Wolfpack.
That said I think Filoni's attachment to wolves is extremely over-hyped. I don't recall much in the way of wolves in Avatar: The Last Airbender, Kim Possible, Clone Wars, Star Wars Resistance, King of the Hill, or American Dragon Jake Long. He's got a handful of wolf mentions but it seems more like he likes animals to me, such as Ahsoka being associated with a bird named Mirai and Ezra with Lothcats.
If you go through his full works you'll find he doesn't throw wolves around like crazy, he throws Godzilla into everything. Multiple characters in his works are named after Godzilla actors and directors (Hondo Ohnaka is named after two Godzilla actors, Ishiro Honda and Seiji Onaka). Just about everything he makes has characters named after Godzilla creators and he often finds a way to work some kind of Kaijuu or at least really big animal into the story (Made most obvious by the Zillo Beast arc in Clone Wars).
