Minnie had started that but she just like Bingo get's scared of my stern voice...lol so she stops and she don't continue to chew or tug on anything or anyone for long....Thank god I give her most of my attention when she is running around the house I whistle and call her name so she can come back to me...She like's to follow her big bro it's understandable but he don't like to be bothered...when she come's when I call her she sits and wait's for my response....most of the time she is away from me is either when she is eating or chasing her big bro....she don't have bad biting habit's luckily I do take her out even though she don't have all her vaccinations but I take her out for fresh air in my arms.... so she enjoy's that I play a lot with her and so does Bingo so she get's pretty tired.... they love and need a lot of attention they are just like human baby's... that's why I think it is great having two cause sometime's when I'm busy she is bothering Bingo and he is playing with her tiring her out... so it manage's well but all I can say is just play with him a whole lot keep him occupied as much as possible when u see he is doing something wrong turn his attention to something else and he will completely forget I do it with Minnie and he should be fine in no time but have patience and don't show him ur giving up cause he will just continue being a spoiled boy hope this helps
