I tend to fall into the group of people who say that Rottweilers are not the breed for everyone. Why I say that is because I've been in the breed for several years now and have owned them when they were really a "Black Listed Breed." When I got my first Rottweiler in 2000, most of my family on both my side and the in-laws thought I was crazy to own "one of THOSE dogs!" "They eat babies!" "They will kill you in your sleep!" "They turn on you!"
But...they went through a period of time when a lot of people owned them who had no business owning a rottweiler for whatever reason. They were the breed that made the headlines on the news of killing, injuring, or maiming people. This is a breed that has the power and strength to seriously injure or kill someone and they did it enough to get that reputation. Homeowner insurance companies for the most part still won't cover people who own Rottweilers. So, I am very protective of my "heart breed" and I don't want to see them end back up on the front page because some idiot got a rottweiler who didn't have the drive or wherewithal to properly train/care for it and that dog injured or killed someone. Yeah, you can say it's ego....but I also don't want someone to ruin my right/ability of owning my breed because they were careless with a rottweiler in their care. But I see it all the time on the Rottweiler Board I hang out on...someone gets a cute little rottie puppy and then gets in over their heads with the adolescent dog where it's menacing people, dogs, and their own owners, etc. Accidents waiting to happen. Some people put their grown up pants on and learn how to manage the dog properly and many do not.
My concern about people owning rottweilers goes beyond whether a dog is matched well energy wise with an owner...I'm more worried about safety and the responsibility to own my breed and not have something catastrophic happen.
