OK so i got a new puppy, not quite sure what she is or how old she is but i believe she is part rott and lab.. The guy i got her from said she was about 9 weeks he thinks. this was a week ago so 10 weeks? she weighs prob about 10 pounds now. Ok well i have a few problems with her. She is doing well with potty training and has had few accidents inside the house. But what she is having problems with is biting, and listening to me when i tell her no/stop doing something. If she bites me i tell her no and move my hand away out of her sight. sometimes give her a toy with other hand immediately. But heres my problem sometimes instead of gettning the toy she will go for my other hand or as soon as i take away my hand she barks at me and goes after my other free hand. This also happens when i tell her no when she is playing with or biting something she is not supposed to.. She just barks at me and continues to do it.
