We rescued an approximately 3 month old lab/terrier/boxer mix female from the pound a week ago. She was a stray that someone brought in. She was spayed the day we brought her home. She was very loving and sweet for the first couple of days. She's very happy and loving to strangers and other dogs.
Towards us, she's usually sweet and loving, but occasionally she'll start attacking and biting our legs and our feet. We think her tail is still wagging as it seems she is trying to play too aggressively. The first couple of days she did this we over reacted and held her out and away from us by her leash. We stopped doing that after a couple of days and just ignore her and tell her no. She continues to bite and get crazed even when we tell her a firm no. If she stops for a few moments and we try to take a step she will immediately growl and snarl and bite some more, even jumping up and chomping above our knees.
She doesn't bark when doing this or very often at all-- she's not a very vocal dog most of the time.
Outside of these situations she only growls a tiny bit when playing rough with a toy by herself.
When she's not crazed she's a good puppy.
I believe she's afraid of running noises as she gets crazy when one of us runs with her on the leash. How can we go about introducing this to her, without her continuing to bite us.
We did notice a few times when we fed her, she calmed down. We aren't sure if it could be a blood sugar issue (as sometimes she doesn't eat all of her food when it is given to her.) But we also think it could be that her taking the time to eat distracts her from the crazed state and she just gets calm again because she is refocused on something else.
Once we can get her calm either with a small amount of crate time or making her sit and stay on the leash for an amount of time, she goes back to being a sweet girl with what i would consider a typical amount of puppy nipping that is easily satiated with a chew to.
How do we handle her in those situations and ultimately put an end to them?
