Hi, I'm new to the forums and need advice ASAP!! I was looking to get a new dog a while back and did some research on several different breeds. I was looking around and found a doberman puppy, 4 mo old male, at a rescue league. I took him in a few days ago and just love him. Now heres the problem - when I was doing my research on the different breeds I never came across the male on male aggression that is common in dobermans, I guess I wasnt looking at the right websites, and the people at the rescue league said nothing about it. I just happened to be surfing the web looking at different training options for the pup when I came across an article about it. I have a 10 year old lab/chow mix, male, already. I'm supposed to sign the adoption papers for the pup tomorrow. I want to keep him, but now I am worried. Is it truly a bad idea? Should I give him back to the league and find a different breed of dog? HELP!!! Thanks for any advice.
