We are another who's trained with her, seen her dogs and thinks highly of her/Theishof. She was and perhaps still is the breed warden for our area.I am local to Theishof and at one time trained with Heidi when I needed help with my reactive dog (who did NOT come from her). I love her dogs. She is very, very knowledgeable about the breed and I respect what does with her dogs. She trains and trials herself, so she is very aware of what she is producing.
She keeps her retired females as house pets, which always amazed me. I would knock on her door and the two retired girls she had the time would be standing at the ready when Heidi answered. The Theishof dogs are known for being good house dogs and family companions, as well as therapy dogs and successful competition dogs.
