I'm concerned about the hip most of all. Make sure you see your veterinarian immediately about it.

I love Labs!! You will have so much joy with this puppy. Puppies are very energetic and tend to bite and jump. The best way for you to work towards correcting is to remember to be patient, never strike the puppy, and if possible enroll in a puppy kindergarten class. They are great for socializing and teaching you how to teach your puppy. Also, make sure that you keep a fresh supply of chew toys around to put in the puppies mouth when he starts mouthing you. He is getting new teeth and his mouth hurts, so you are a good chew toy! Make sure you say a loud "OUCH" when he bites you. You can also freeze wet washclothes for him to chew, and maybe even give him some ice periodically. There are some really good books out there about training puppies too, so you might get one. It will be your Bible while raising your puppy!

And the last, probably most important thing to remember is:

A TIRED PUPPY IS A GOOD PUPPY, so make sure you're playing with him a lot so he can work off that extra energy. But get that hip checked first. You certainly don't want to damage it further.
