How to tell if my dog is a purebred Rottweiler or a Doberman mix?

Updated On September 23rd, 2025

Pet's info: Dog | Rottweiler | Female | unspayed | 9 months and 19 days old | 76 lbs

I as well as some others believe my dog is not a purebred Rottweiler. Both another and I believe she might be a Rottweiler + Doberman mix. With your experience, could you please be able to discern if she is a purebred Rottweiler and if not, what probable mix she is (see also photos)? She does have the temprament of a Rottweiler and the correct visual colour markings but not the size. She is fully vaccinated, thoroughly dewormed and fed high protein diet - Thank you.

There is no way of knowing from pictures or temeperament - individuals of any breed can develop differently and some will be finer or smaller than expected even within one full, purebred litter. Ensure she is on a large breed puppy food and up to date with deworming etc so she develops to her full potential. DNA testing of her and her parents could potentially prove the parentage but it would not be impossible that somewhere in her ancestry there is a mix of breeds
