I recall having Charlie take the Volhard Puppy Personality Test, and he was "medium" on all categories except for Prey Drive where he tested "high". After the "bird incidents" yesterday, I recalled his breeder telling me "Most of my dogs will even go to ground." It was interesting that the terrier dog who was visiting us yesterday had absolutely no interest in the (first) baby bird that Charlie caught. My point is that any dog, mixed or pure-bred, can have a high or low prey drive. The Volhard test might help you choose a puppy, but would not be an absolute guarantee that a stronger prey drive won't develop. Training can help encourage or suppress drives, but the instincts won't totally go away.

I also know that a lot of dogs will see other animals living in the house as pack members, but unknown animals or wildlife are not considered pack members. Charlie won't chase or harm my three cats, but it wouldn't surprise me much if he went after a "strange" cat that might happen into our yard.

Whatever puppy you choose will be easier to train with the birds if the pup has a high-pack drive and low-prey drive personality. The breeder would probably be the best one to tell you.
