Sadly, it's not real , 'cuz Balto was fixed. But he really was a wolf-dog, but owned by Leonhard Seppala and mushed in the Serum Run by Gunnar Kaason.

Balto 2 and 3 are not real because it involes there puppies and the real Balto was fixed.

Not real.

They're made up. The real Balto was part wolf, Was neatured
so he couldn't breed, And Jenna,Steele, and others never
excisted.

if i have the best answer ,here it is
Balto 1= true
because it act like a little bit of the true story
Balto 2= not true but the town named Nome in that movie
is true by the town
Balto 3=not true same thing i said
to balto 2

They're made up. Balto didn't have any son (he was neutered)
and he wasn't even a wild wolfdog (but a pure husky). Balto
1 is BASED on a true story (which means it isn't 100% true).
The real Balto left Alaska a few weeks after the Serum Run
and never came back.

They're made up. Like Banshee said, the real Balto was
fixed. In real life he was a husky.

what banshee said

Balto 2 and 3 are made up. Balto was fixed in real life, so
he could not have had Aleu.. or kodi. And the whole wolf
quest thing didn't happen. Balto wasn't even wolf in real
life.
