You have had some good advice on here. I rescued my terrier at 7 months from a pet home, he had never been walked and didn't even know his name, couldn't cross puddles, got lost in long grass etc. Basically like an 8 week old pup in a great big body. It took some work and some time with my friends bushing pack but he turned into a really good dog, does everything I want, bushing, ratting, flushing and more. His only failing is that I never managed to break him to ferrets which is a real shame. I would recommend getting the ferret thing and the bonding done first, then get her used to being out
