I'm not sure if I'm posting this in the right section or not, but I really don't think its a training issue, so here goes.......
I got a new baby 3 weeks ago. I posted pictures of her in the picture section

but for those who didn't see I will post another here.
Her name is Ivy Lou...she is 9 mos old, 5.5 lbs..Ivy is a very active and outgoing pup and happy or I thought anyways.
Ivy was returned to my breeder about 6 weeks ago...the new owner told my breeder that she couldn't keep her cause her hubby didn't like dogs, which throw my breeder for loop cause she never told her that her hubby didn't like dogs cause if she had she would have never sold Ivy to her. And Ivy waking them up at 3am to go potty

that was her excuse for returning her.
Yesterday my daughter stopped by for something to eat before going to class, she is in college. Well she left the bathroom door open and Harley my paper shredder, went in there and got a whole roll of toilet paper...he had it everwhere in the hall way and living room

I always take a deep breath and let it out when I find that they have been bad...than I start singing the Cop song...bad boy bad boy what am I gonna do, what am I gonna do with you...LOL I change it to bad girl when its Bella LOL....well Bella and Harley thinks its a game and they start barking at me and dancing around...I say they are back talking me...but anyways...I noticed as soon as I took that deep breath Ivy Lou coward down and ran to her bed and just started shaking all over, she was scared to death

it just broke my heart...I picked her up and cuddle her, held her close to me until she stopped shaking and I put her down, she was fine at this point but I wasn't I just cried my eyes out. none of my babies have ever been scared of me but Ivy was
I think Ivy was abused or yelled at very loudly by her first owners and their reaction before the yelling or abuse was taking a deep breath like I did...We could be wrong but I don't think so.
So my question is...do you think with Ivy's reaction to my deep breath, shaking to death with fear...is a sign of being abused? and along with love and building her trust in us, What else if any can I do to reassure this sweet baby I would NEVER hurt her?
I have never asked for advice here before, I have always been very confident in my training ability to raise happy healthy yorkies but Ivy's reaction yesterday has shook me to my core.
