My staff is 9 she went for the birds once when she was a pup, she never ever done it again. And she is still as lively as a pup, she is more like a sheep(pigeon) dog,it's weird but she knows ever bird in our lofts and if there's a stray shell walk it out of the bunch, amazing really. I have 100% trust with her, she has been brought up with 7 toddlers, and she loves all my nephews and nieces as well as my own son, and treats them as if they was her own pups. Staffs are known as the nanny dogs, it's just mugs who don't treat or train them right and for the wrong purposes that make them have a bad rap.
