What can I do to control my Akita puppy from continuously biting old Siberian husky?

From your question it seems to me, that the akita puppy is having some complex issues with your Siberian husky. It can be a possibility that the akita puppy might be having stored a myriad of jealousy against the Siberian husky since it is old and you might be, unknowingly, parting a lot of attention toward the Siberian husky as compared to the pup.

Now, firstly make the puppy understand that it needs to live in the house, by acknowledging the presence of the Siberian husky. You have to take both of the pets to dog gardens and make them walk and try to make the break the bread together, that adds to the emotional quotient. Make the pets play with some common toys. All these things will chip in making both the pets to be as thick as thieves. Good luck.
