I have had 5 dobermans over the years & am totally in love with the breed. I presently have 2 females that I rescued. They can be trained to leave the chickens alone. (or any other small pets you have) My recent rescue has been with us for just 3 months & came from the pound with a high prey drive. She immediately started chasing the chickens & the cats. Within 2 weeks she was a changed girl & is now completely trust worthy with the cats, but I do still keep an eye on her when the chickens are out, just in case. To be able to have a "good" doberman you simply have to mean what you say to them & be consistant. They are not the kind of dog that listens to a wishy-washy owner. If you gain their respect they will be your biggest ally & friend for the rest of their life. Buckeye lady is completely right about them being able to detect danger. I have always trusted my dobies when they "told" me something wasn't quite right about a situation or person. I also know of 2 rescue groups in southwest ohio if needed as well.
