First time Rottweiler owner - questions
I just have a few questions about Rottweiler's. I was thinking about getting two Rottweiler's.
Would having two females be a good idea or not?
If so would it be wise to get them from the same bloodline?
The first thing I suggest is that you do a LOT of research on this breed, as they are not really recommended for first-time dog owners due to their sheer size and strong-will. If you have owned big dogs before and are familiar with caring for and training them, but just haven't owned a Rottweiler that is different.
I do have several pages that go into a lot of detail about this breed, their traits, behavior etc. I'd recommend that you read these pages to begin with..
Caring For Big Dog Breeds
As for your specific questions..... I personally wouldn't recommend getting two puppies at the same time - ever. It's an amazing amount of work - many first time dog owners are totally unprepared for the amount of time and effort it takes to care for ONE puppy, let alone two. It is also much better in terms of bonding and training to have just one pup to take care of.
Secondly, whenever you have two dogs of the same sex there is the potential for conflict, and in dogs the size of Rottweilers that may lead to serious trouble. It's always better to have dogs of the opposite sex and have them spayed/neutered to prevent unwanted puppies and reproductive order diseases.
Two puppies of the same sex will get along to begin with, but as soon as they begin to mature the squabbling is likely to start. Two pups of the opposite sex will likely squabble too, but they won't be as aggressive about it and there will be less combative behavior.
Dogs don't recognize family the way we humans do, and even two pups from the same litter won't have any special feelings for their siblings... or even their parents. So whether or not they're from the same 'family' or bloodlines won't make any difference.
And finally, do take lots of time to research breeders and if you decide to buy a Rottie pup, choose carefully. You want a healthy pup, from parent dogs that are healthy both physically and temperamentally. Check out my Choosing A Rottweiler Breeder page for help with this.
I hope this helps and wish you the best of luck with whatever decision you make.
