I got my working line dog from Warkonhaus (pic in my avatar). She’s located in State College, PA. She’d be worth checking out. I don’t believe she has a litter available now, but she has future breedings coming up.
My dog is very active, very biddable - his focus on me is off the charts, high pack and prey drive, very playful, great gripping behavior, not prone to excessive barking, recovers quick from being startled, actively investigates new things, not noise sensitive- sleeps through thunderstorms and fireworks, great in the car - not motion sick, not destructive in the house, could chase a flirt pole until his feet fall off, loves to learn and be with me. Easy to live with in the house. He’s currently two years old.
My only issue with him is leash reactivity especially to other dogs. But that is not his fault. He was attacked by another dog and my handling of it made it worse (he does love the dog he lives with).
Although, we were at training a few weeks ago and he licked a strange non-reactive dog in the kennel next to him. Never thought I’d live to see the day! LOL
