puppy behavior

[brady]

I have a question. I am not sure if this is normal or not. Brady and Tim are doing very well, I was afraid Brady may be too rough with Tim but I was very wrong. Tim actually bites at Brady's ears. Brady will take just so much and take off. I watch to make sure he isn't too rough with Tim but I think he can hold his own. He actually shows his teeth at Brady and growls. He is just over 3 months old and has had very little if any socialization with people and other dogs, just the little bit in the last week before we got him.. I have been just letting them work it out. Is this the right thing to do?

I would let them work it out, and in about a month, I would try to get him socialized as much as possible while he is still small enough and easily trainable.
