I agree that they will grow accustomed to each other in time. Tezel may think it is job to bark every time your puppy cries or makes a sound. I would try redirecting his attention to something positive, like a game of fetch. You can also do things that involves both dogs, like obedience/trick training.
Training helped my boys form a bond. Short sessions of tricks for treats distracted them wrestling. We do simple things like sit, down, shake hands, and so on.
