I know it's only been a few hours but Joel hates him! LOL He's really sad

I sure hope he gets used to him and they're best friends. He doesn't like him getting his toys either. And sometimes nips his face, I'm not sure if I ignore it or tell him stop?
I'm making sure to give Joel lots of attention but it's kinda hard when I have to keep on the puppy too. Dixon is adorable but I forgot how puppies are haha.
Also they're almost the same size(for now!) Dixon is about 2 pounds bigger
