If you want to ask about a breeder, ask about the breeder. It's kind of in bad taste to go about it that way. Post the breeder's kennel name, ask for reviews of Von Schwarz and her dogs. https://www.vonschwarzdobermans.com/Is this considered good?
Why would any breeder of working dogs want to sell you one of their best working prospects when it is obvious you are not serious about working the puppy? Sounds like you are just looking for a pet to me. There are plenty of people that will sell you a pet.I’m looking for a companion dog who I can work here an there at local working clubs.
