Ginga: Nagareboshi Gin
Where these dogs fight the bear Akabuto and his minions.
It ran from the seventh of April to the twenty second of September 1986. (Very old anime)
My favourite characters are Akame, Akatora, and his brothers Kurotora and Chūtora (hence my profile picture and banner)
I wish they remade this so it has a English dub and subbed versions.
