Aww First of all Welcome to YT!! Glad to have ya.
That is so awesome of you, Congrats on adopting!! Is this your first dog?
I know Puppy Mill pups are different, from what they have been through it’s hard to say how they will act when she is home. I would maybe just take it day by day, just to see how she is going to be- Are you going to have pads out? Take her outside to potty? When are you getting her? I know a lot of member's have exp in puppy mill pups so hopefully they can help you more-
Looking forward to hearing more about her and seeing pics!!
