I have two dogs from this breeder.
Female 3.5 years old and puppy 5 month old.
I was looking for companion dog, not show dog. Wanted to do some training etc, but nothing professional.
Nuka(older) is a great dog. Great temperament, loves everybody, especially kids. She is a hard working girl, smart. I'm not a professional but that was my first owned dog and I made my research about breed before I got her so I knew it GSD need good handling. I wish everybody puppy like her. Never had a problem with her. Potty training first day, no chewing, little nipping that stopped after teething, very obedient, no aggression, very stable.Would you imagine a 6 months old puppy standing in front of 5 deer's and not run after them, not even tempted to do so. She wouldn't leave my side. I've train her by myself, so by 5 month(got her at 11 weeks) she new it sit, down, rollover, play dead, back up, circle, side, shake, high five, leave it(on paws, on the nose).She is very patient. Kids ridding on her pulling her by her tail, never even looked at them bad, she just gently walk away. When she was one, I start doing with her sniffing games, cause she was always into sniffing. She caught that quick, so I wanted to sign her up for tracking but nobody had it in my area, cause it seems they all moving into Nose Work.so I started Nose Work with her at For your K9. She has right now NW2 plus for last title 2nd place overall and 3rd place in Interior. Unfortunately we didn't made it to the last Trial in the Schaumburg to do NW3, but in fall we hoping they gonna pick us

. You can check those results on official nose work website. She got that title last year 11/02/2013 in Geneva, IL (Alicja Szkobodzinski, Nuka).I'm getting complements about her from other trainers, vets, owners how good temperament this dog has.
When it comes to Nazar(parents Yvonne, Max) . He is a great boy. Putty training went longer around two weeks.So far no damages around a house. Again no signs of aggression, loves again kids. I would trust him about wild animals :laugh:. He wants to go after him

I've sign him for basic obedience for puppies(not like I can't train him, but I want him to be socialize with other dogs and people, and let him to be used to around lot's of dogs).He did great. He was the youngest in the class(11 weeks). He was the bravest. Interacting with others with no problems. Quickly learned all the tricks and he become valedictorian of this class. Right after his class I've sign him in for Nose Work and also he is doing great. Nuka is fast when it comes to search, she want's to find it right away, sometimes doing that without "plan" in her head. Nazar is more wiser he has a search plan.
Also Nazar is more "I want to be close to you" when Nuka is more independent, but still will not leave my side. But from what I heard from other GSD owners that's how it is. boys are more affectionate then girl.
Besides that I want to sign him for rally. He is more thinker, calmer buddy, but that's good cause Nuka is a ball of energy.
So as you can see it's not necessary has to be a breeder that you will pay 10k for puppy. I have my two babies that are doing fine, both temperament that I was looking for. Never had a problem besides regular puppy staff or something that I was freaking out because of my lack of knowledge(like Nuka is laying down when She meets other dogs).
So I just wanted to put my opinion as of the owner of dogs that came from that breeder. I'm not a friend or family of the breeder, just client.
If you have more questions you can pm me.
