We got her like a month ago and she has been starting to show very strong signs of aggression she bites,she growls,she barks at little kids and a lot of people keep saying "oh shes just a puppy" "oh she is just teething she will grow out of it" but what happens if she doesn't people could sew us and then we would have to put her down:eek:

What about taking her to puppy obedience school?

Be sure someone isn't "teaching" her how to be aggressive by teasing her etc.

How old is she? The key to most behavior problems is approaching things using the dog's natural instincts. 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 Raising Your Dog with the Monks of New Skete You don't want to to take her our around strange dogs in an obedience class until about 5 months. I start teaching my puppies obedience the day we get them at 7 weeks. The younger the puppy, the faster they learn, as long as you keep the sessions short, just a couple of repetitions of a command.

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. One thing you can do at that stage is to knot and wet a piece of cloth. Then freeze it. The cooling will soothe the gums. Only let the puppy have it when you are there to watch it. 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.

You just have to keep on correcting them, hundreds of times, not dozens.
Provide sturdy, safe toys such as Kongs and Nylabones. Avoid things they can
Chew pieces off and choke on them. Keep them away from electrical cords.
Crates are essential for most young Labs and other dogs.
