yellow lab is standoffish

Question
I have an almost 1yr old female spayed yellow lab.  We adore her.  The problem is she may not feel the same way towards us.  When outside, very playful and enthusiastic.  Inside she doesn't want much to do with me or my family.  She stays by herself in the kitchen or her crate(which is in the family room) while we are in the family room.  At times if she is laying on the kitchen floor and you walk in the room, she will get up and move to avoid you.  If we try to pet her, she does the same thing - trys to get away from us.  Not sure if this is her personality or if we could have done something to have caused this behavior.  She is well cared for, mostly by me, walked for almost an hour everyday and when possible socialized with other dogs.  She is well behaved all in all but it is almost hurtful that she doesn't want to be part of the family when we are all sitting in the family room.  Any advise would be greatly appreciated!!!

Answer
Yeah, I have had them get up and go to their crate when I petted them.  they seem to go through an independent stage.  What you can still do of this will help:

''Elevation for small puppies: Sit on the floor and gently put your hands around your pup's middle, below his front legs, and lift him up. He is facing you. Hold him for 15 seconds. Repeat until he no longer struggles. If he is past 10-12 weeks, lift his front feet off the ground, but don't pick him up.

Cradling for small puppies: Hold your puppy gently on his back, as you would cradle a small baby. If he struggles, hold him firmly until he quiets for 10-15 seconds. With larger pups, you can do this as your sit on the floor, with your pup between your legs.

Quiet lying down: Place your pup on the floor on his side, with all 4 legs pointing away from you. Use your hands on his neck/shoulder area and middle, to hold him in this position. When he is quiet, praise him. Lengthen the time that you keep him quietly in this position. When he accepts this position well, handle his paws and muzzle, while keeping him quiet.''

The quotes mean this isn't my original work. It is copied from my Puppy Raising Manual. I have long used these or minor variations of them, and they are very effective. You may want to give him a belly rub while he is on his back too. Helps bonding. There is a big difference between him rolling over and demanding a belly rub, and you choosing a time to roll him over and rub his belly. The latter cements your place as pack leader.
