I already have several scratches from her needle-like baby teeth on my hands. I did try everything I've read online such as distracting her with her toys so that she bites them instead of my hand, say "ouch" and turn away from her, and a more "aggressive" posture as well as to show dominance. Nothing seems to work. What should I do? What am I missing? She's otherwise very sweet and affectionate but stubborn and doesn't allow me or doesn't want to acknowledge me as her master so to speak when I try to educate her. If she was a bigger dog I would have my fingers off by now it seems. Help!
Edit: she's socialized and is never left alone at home.
Set yourself up an exercise pen, or a large crate, whichever you want. Put some nice chews and some fun toys in the their since you don't want to turn it into a punishment zone.
First don't take the toy away from her, you want her to bite the toys and not you so it's counter productive to take them away. Praise and play with her whenever she has a toy! If you want her to give you the toy teach her the drop command, and or play trade games with her. When she drops the toy she gets the other toy or a yummy treat then the original toy back.
Spray the furniture with bitter apple spray, or any of the no chew sprays available, sometimes they work sometimes they don't it's puppy dependent. If she chews that furniture despite that redirect her onto an appropriate chew. If she chews on it tell her she's a good puppy. If she goes right back to gnawing the table leg, couch, etc. redirect her again, she does it a third time then put her in the crate, or exercise pen for a few minutes before letting her out. Over and over, eventually what she will learn that trying to eat the furniture gets her put in her exercise pen, and she'll stop. Ignore the finger biting when you put her in there even if she's pitching a fit, BUT you'll need to work on her tolerance of being picked up. Ask if you need help with that last bit.
If she's being a furry little landshark, and just attacking toes and pant legs, give her a toy and play with her when she does that, if she drops it and tries attacking you, give her the toy again and try playing, if she goes for you a third time then get out of her reach, either get on the couch, bed, or hop a baby gate, whatever you need to do to end her fun time. Again it'll take time but she'll learn that if she bites you you go away, and the fun ends, if she plays with a toy then you stay and she keeps having gun.
If she's just throwing a temper tantrum it might be that she's over tired and would benefit from some down time in her crate or exercise pen. Usually when they are biting monsters due to that they'll fall asleep once they are in the crate or pen.
Oh knock off the I need to dominate her stuff, all you'll end up doing is scaring her, that's all. In the end it can backfire if she starts biting out of fear.
One thing to keep in mind is just because she's tiny and is going to remain small does not mean she should get a pass on bad behavior. She can be taught manners same as any other dog, it just takes patience, gentleness, and time. By time I mean it'll usually take a few weeks for them to really catch on, it will not happen in a few days and definitely not over night. You need to stick with it and be persistent.
