I agree with Polly, get her evaluated. Treats do work very well, I like Kathy use different treats. I have regular witch could be bits of their food or high value depending on what the task is. Puppy class is great for socialization and also for answering any questions you might have. Was Olivia groomed ever when she was very young? My Amelia is great with grooming, but then again the breeder had started grooming at 4-5 weeks of age. Those puppies were always brushed and worked with. I can remember going over there to help bathe when those babies were about 9 weeks. I bathed Amelia and put her on the table for drying we used 2 dryers, I dried one side the breeder dried the other, she just stood there. The more you work with them the better they are. One thing is not to let her bite/ chew your hands when she is playing. My trainer would say if the puppy tries to chew on your hand say ouch very loudly, that distracts them, grab a toy and put it in their mouth. When handling to do any brushing etc, talk in a very calm voice, have a toy with you, she liked the rope toys, give that to the puppy to distract. Yes food does help as well. Make everything a positive thing. Short frequent sessions with lots of praise. Good luck with everything.
