My pup shows aggression towards me by growling and showing avoidance. What can I do to create a bond between us?

Hi Cindy & Ed,

I purchased a german rottwieler pup to raise for personal protection. She is just over 7 weeks and I've had her for 6 days. I studied the video your puppy 8 weeks to 8 months before I got her home and been doing much of the training shown in the video with moderate success. I have established a value for yes, and the pup is consistent with the touch command. I am an amature handler under the supervision of my husband who has a great deal of training experience. My concern is that my pup shows aggression towards me by growling and showing avoidance after I use food reward for the touch command. She will come to my hand take the treat and as I praise her and rub her back she will growl and try to leave. This pup also shows avoidance by not showing much interest in me, I will sit on the floor in front of her to try to encourage her to come to me or play with toys and she usually stops a few feet away and just sits there looking disengaged. She seems very independent and aloof. I know I am supposed to be her source of fun, what can I do to create a bond between us?

Thanks for your help!
