I think that my dog has a great pray drive, police officer (dog trainer) that worked with her briefly told me the same thing.
She will give 100% chasing a ball no matter how tired she is. She loves to chase, toys, laser point, rain drops, snow... and she does that extremely energetic and I can see sometimes that she raises hairs on her back just before catch.
The thing that confuses me is her lack of interest for the living things (small animals), not that I complain
I'm grateful for that I'm just confused. She only hates cats but that started when she was 18 months old, cat jumped on her and scratched her nose.
Are those two things separable?
She had great ball drive from the first day with me (7 week old) and I never thought her not to chase animals because she never did. She does responds to noises and rushes toward, but when she realize it is a living thing (hedgehog for example) she just sniffs and turn around.
