What is the opinion on DCM in regards to the American and Euro lines? Are they both equally effected? I have had two dobermans with many health issues. Going through my boys with one having CAH and DCM and the second now having DCM, I did contemplate changing to another breed. It has been a heart ripping experience, but these dogs have bought so much more to us. Also, I've read the temperament with the European line is sharper.
