You should post some pictures of your dobermans. I will get a doberman sometime in my life. I saw one a couple months ago in a grocery store, they are such noble dogs. I'm pretty jealous you have 2. Right now I have two pitbull mixes (my labrador was put down last year :( ). I had more issues with my Lab being aggressive than my pit's...I also have problems with other dogs attacking my dogs, and my dogs tucking tail and trying to run away.
Anyway...there are few topics I will get pretty defensive about...and when someone bashes my dogs, even indirectly, you will be sure to see me show up :) I would like to see pictures of your dobermans though!
