How do i know if i have a real rottweiler if they look like doberman dogs?
And do rottweilers have to have a big head when they are 3 months old?
The only way to know for sure if you have a purebred Rottweiler is if the puppy is registered with a reputable registration organization, and if the parents are also registered.
Registration papers indicate that the dogs' lineage is purebred. If you don't have papers, then there's no way to tell for sure that you have a purebred Rottie, or whether or not he/she is of mixed parentage, perhaps with Dobermans. Even if both parents look like Rottweilers they could still have mixed heritage.
As for the size of a Rottweiler puppys' head, a lot depends on the bloodlines and conformation of the parents. Some bloodlines have bigger, heavier bone structure than others. I'd suggest that you look at my Rottweiler Breed Standard page for more info. on how a Rottweiler should look.
Hope this helps. Best of luck.
