agressive pitbull argentinian dogo mix puppy
My dog is very mean whenever she sees my sister or cousin (both toddlers) she tries to tackle and bite them.She has also not been eating her dog food and we have given her bread and chicken and she now only on rare occasions eats her food.She has now teared through the bottom of the couch and went inside and when we tried to get her out she started barking very loudly. She use to be very nice and calm but now she bites our:couch,face,arm,hand,ankles,feet,shoes,socks,table basically everything but her chew toys. She has very sharp teeth too
shes only around 7-8 weeks
we take her outside everyday as well
Is this because of her breed?
How do we get her to calm down?
Is this because of her age?
