Help!!! Pirahna Puppy

Congrats on your new puppy[]
 
First, what does she have to chew on?  For puppies I like rope toys and kongs.  Also, I take an old face cloth or sock and get it wet, tie it in a knot and freeze it.  When it's nice and hard I'll give it to the pup to chew.  I think you can acually buy some toys for pups that are meant to be frozen like that but I like the ones I make.  When it's thawed it gets rewet (and washed off if it needs to be) and refrozen.
 
Second, make sure your're not making the crate a place for punishment.  You want it to be a happy place.  If you have to put her in there put something in there for her to chew or reward her with a treat for going in.  If you're putting her in there for biting I guarantee you that by the time you pick her up and put her in her crate she has no idea that you're doing it because she bit you.  Think of it as a place for her to settle down, not be punished.  Ignore her "talking back" and don't let her out unless she's quiet.  She's just manipulating you - puppies are experts at making us feel guilty. 
 
Keep working on the "no bite".  She's only 12 weeks old and you can't expect her to obey you all the time.  Be firm and consistent with her because now is the time to nip biting in the bud.
 
Have fun with her!

she has a puppy kong, a rope toy, a squeaky toy, and nylabones in the stages.now she has two- the one she started with, and the one for 3 months that tastes like bacon i think..I'll try freezing the rope- that may work. As for the crating, she looks ashamed when i put her in there when she bites, but she still loves to sleep in there at night, but maybe i'll have to rethink the "penalty box" thing. I guess she's moody, because sometimes she's very good about listening to the no bite, and others she just doesn't care... i guess its puppyhood. She's great fun, and we really love and enjoy her, sometimes she just doesn't listen...i guess that goes for kids with fur as well as human kids...

This is all perfectly normal puppy behavior.  Pups explore the world with their MOUTHS just like human babies do.
 
Correct (no bite) redirect (give an acceptable chew thing) and PRAISE like crazy when she chews on an ok thing.  I dont crate pups for this....I withdraw ME from the picture, but don't ever lock the pups up.  Of course, my last pups were a litter of seven fosters......

The "penalty box", while it removes her from the situation, may actually be harmful.  Two things reduce nipping - prevention and exercise (not getting that in the penalty box LOL).  You are on the right track having appropriate chew toys.  Instead of putting her somewhere, YOU leave when she nips. This is how pups learn from other pups to inhibit their bite.  Puppy thinks, "Hmmm, let's see - I bite, my playmate yelps, and leaves.  Guess I better not bite so hard next time if I want to keep playing."
Also, a tired pup is less likely to be nippy from boredom or the puppy heebee jeebies.  Play fetch (even if he doesn't bring the ball back yet), get into puppy class, or find a puppy play group with dogs his own age.  Find a neighbor with a pup he likes.  Etc.

What your puppy is doing is perfectly normal. they explore the wolrd through their mouths. usually, puppies play with other puppies in the same pack by playing rough - this includes biting others within. they will even sometimes bite their parents for attention. as long as this does not develop into anything more than a harmful snap then you should be fine. just make sure there are plenty of substitues for her to chew on. my dog was exactly like this when she was a puppy - she even destroyed our whole furniture set and many items of my clothings, but now she is perfectly happy to chew on her kong or bone. i would not suggest promoting this behaviour so when ever she bites you just stand up and ignore her for a a few minutes until she has calmed down.by doing this, hopefully, she will realise that this is not the way to get your attention. never use a crate or penalty box as this will just encourage her to bark or chew or do something for attention.  [sm=tex.gif]
