Hello, you’re very lucky to get her!
There are plenty people around with experience of ex breeders. I had a springer ex breeder but she wasn’t from a puppy farm However, she was a clingy nervous wreck, literally scared of her own shadow. She was confused by outdoor scents. However her brain was hardwired for chasing a pheasant on her second day. It took a year to adapt, my neighbour had a rehomed stud dog, equally nervous. Sporting dogs like spaniels whether show type or working, cant cope with being locked in any kennels. They don’t always get their confidence back.
