10 weeks is awfully young to label a pup aggressive. They just need to use positive reinforcement. He's plenty young enough to learn. He's a doll by the way.

Jess, maybe this won't help but this is what we do.  If our dogs growl or be real bad, we put our hand on their neck (hard but not enough to hurt) and put them to the ground and growl at them.  This shows them that we are the dominate one.  It's also a way of scolding since mothers do that to pups.  Have them start now sitting with him when he eats.  Pet him while he eats and every few bites, give him the food from their hand.  This avoids food agression.  If he gets snappy, a firm "NO" is good.  If he tries to bite, try grabbing the top of his nose by wrapping their hand over the top and push his cheeks into his mouth.  He then bits his own lips and learns it hurts a little to bite so maybe he shouldn't do that.  Give the "no" then too.  I'll keep thinking.

bump for Jess.
