Young Labs, which I know best, and other puppies tend to very bad about
Biting. You see a litter of them, and all the ones that are awake are biting
Another one or themselves. I am not even sure they realize that when they are
Alone, if they quit biting, they would quit being bitten. At 3 to 4 months
They are getting their adult teeth, and it seems they spend every waking
Moment biting or chewing. I maintain a Lab's favorite chew toy is another
Lab. Otherwise they settle for any person they can. They keep hoping to find
One that won't yelp and jerk their hand away, or growl "Bad dog." and clamp
Their mouth shut. Then offer a chew toy. They keep trying despite hundreds
Of corrections. Another good technique is to quit playing and go away. Be
Sure to praise them when they are playing nice and not biting.
All puppies are like that, even ones given good leadership right from the beginning. She sounds a little more determined than most. How long have you had her? They can be harder to train not to bite if they are removed from their mother and litter mates before 6 weeks. One thing that may help, if you still can, is from behind her, grasp her with a hand behind each front leg and pick her up and hold her. Make sure it is far enough out it can't fling its head into your face. Hold it until it quits struggling and relaxes. If she is already too big for you to do that, try rolling her on her side and holding her still against your knees. Have one hand far enough forward that she can't reach around and bite. In either case praise her when she quiets down. It will take more time, but eventually she will give up if you correct her as soon as she bites the first time, every time. My answer isn't something I have seen done on TV, but what I learned using what I have been taught on a new puppy every year since 1991.
It is important to teach a dog that you are top dog. It is not a matter of being boss, but more of a strict, but loving parent. The dogs see all the
People and dogs in the household as a pack with each having their own rank in
The pack and a top dog. Life is much easier if the 2 legged pack members
Outrank the 4 legged ones. You can learn to play the role of top dog by
Reading some books or going to a good obedience class. A good obedience class
Or book is about you being top dog, not about rewarding standard commands with
A treat. Start at

Working out of a book, you can start spending a few minutes at a time working on basic obedience commands. She will become bored and lose interest after a few repetitions.
