Kodi just has to have some wolf in him. ( like everyone else said) Even that his profile said that he was all dog, not wolf/dog. Also you spell kodi with a i not a y

obviously he's part wolf.. DX his father is.. he just ended
up looking more like jenna, but his paws and build is bigger
then hers, so if he were a real dog.. we might be able to
notice the wolf in him..

i agree with cat.

Well, if its been established that Aleu is part wolf and
that Kodi is her brother, that would kind of answer the
question, wouldn't it?

well said huskywolf

Well, as huskywolf had said, but there is another thing that
plays an important role. Many wolf pups that are born, may
look nothing like their parents, or each other. Kodi IS part
wolf, even though he doesn't SEEM it. Everyone in town KNOWS
he part wolf because of his father. Kodi couldn't he all
dog. Like huskywolf also said, Kodi is on a three : one ratio.
Three parts husky, and one part wolf.

Looks
aren't everything.

--Mayaa

Kodi is part wolf even though he looks like a pure dog.
what we see is Jenna's side acting up on him. As we all
know well enough Balto is half wolf half husky but Jenna is
pure husky so that makes Kodi 3 quarters husky and 1 quarter
wolf.
