I'd get rid of this trainer! I'd never had a dog before either but I knew enough to know that the 1st trainer I hired was a real wack-job! I fired her, lost a chunk of money but then found a trainer who came highly recommended & is wonderful & even cost a fraction of what I was paying Ms. Wack-job. She does it for the love of the furbabies. I go to her obedience class once a week still cause Saffie ( & I ) love it! (Plus we can always use the training)
I think you're great for taking this precious furbaby & giving it a good home & a loving mommy. I would think cuddles & hugs with be MANDATORY, especially after all she's been through in the past.
Keep looking for another trainer...there's one out there that will be just right for you & your baby. You know what's best for your baby & you're going to be a wonderful mommy!
