If you’re getting a PB from a breeder, you can at least make your selection easier. High drive dogs tend to have high drive puppies. So you want to look for a breeder, or specific dogs from a breeder that meet that low drive, relaxed requirement. If you’re adopting, the rescue and/or foster carer will be able to help you select the dog with the most suitable temperament.
At the end of the day, selecting a low drive dog doesn’t always equate to no trouble, but it certainly makes the process easier. As you’ve raised dogs before you know what’s involved, I personally don’t think there’s any more risk with a pittie than most other breeds, you’ve just got to get that training right.
I know it’s different, but I have two cats that I raised from kittens, they are a very active breed but with consistent training and clear boundaries they very quickly learned that the rabbits were off limits.
