Hi

my female puppy has 70 days, she has been wonderfull.

Problem its that she bite hard my girl friend and my Gf start to be worried when dog will be bigger.

Dog randomly attack her leg including skin , today ruined her pijama and her skin. She also bite hard her hands and so on.

She never do those stuffs with me.

Should I just kennel/crate her all day because im not at home ? Sound drastic not ?

she also cry in kennel while in crate she silent


thanks

Dog has been nice with people, usually happy first minute then she even sit or sleep around them even after 30 seconds.

She learned "sit" and everytime I call her she come to me.

we dont play rough with her, we use toys for play

She bite leash, and I already tryed many times if she bite my hands to yell but nothing, so I tryed yell and turn away but still sometimes she bites.

yesterday I bringed her with me to city, we walked and explored for 2 hours, and then she still attacked my gf leg randomly, so its not that shes bored, we do a lot of stuffs together.

Puppies bite, it happens. Redirect her onto a toy. Work on impulse control. Remove her from the situation and crate her if she's too wound up.

The GF needs to be aware that pulling away, making noise, making fast movements, kicking at him, etc will all encourage puppy to continue to bite. I've never found yelling to be effective. To be honest with you I don't really have the patience to continually redirect a pup. It's a good option. I just don't see any fall out from correcting the pup so I don't bother with it.

Sticking my finger down his throat or squeezing his lower jaw(the finger he was biting in his mouth and another below it) has worked the best. Some people will roll the lip inwards so the pup bites themselves but I've found it requires too much coordination and timing for most people to do it. It also seems to make pup shy about you reaching for their head real quick. The mouth squeeze doesn't seem to cause that because I don't have to move my fingers if he's biting me. I don't say anything when I correct the pup. I just let them learn that biting me is unpleasant.

Immediately after correcting pup for biting I put my fingers right back where they were when pup decided to bite me. If pup bites again I just repeat the mouth squeeze. If pup doesn't bite I tell him how awesome he is. If you always just take the fingers away the pup doesn't learn that not biting is rewarded.

I find stuffing something else in the mouth, a sock, a toy, a glove, anything is fine for the pup to grab. Pups like to have something in the mouth.

The girlfriend needs to learn not to be a victim, not to engage the pup in bite games. Let him bite the leash, he will outgrow that. My dog carried his leash for 6 months.

If the pup bites you, not a play bite, but a real bite, I'd grap the pups cheeks with each hand, one hand on each side of his face, have him face you and yell, "knock it off!" then put him away so that he can settle down. Don't do this often, once or twice should be enough for his whole life.
