would like to know if she is a full rotty
It's impossible to say for sure whether a dog is purebred or not by just looking I'm afraid :( The only PROOF you can have are:
a)paperwork and pedigree information from a reputable organization, such as the KC in the UK.
b)DNA tests (there are at-home kits available) can tell you whether or not she's purebred or has other breeds in her genetic make-up.
BUT from that photo of Rikku I would say that she looks likes a Rottweiler. Just like any breed, there can be a big difference in coat, color, height, weight, ear-set and so on between individual pups/dogs.
Sorry I can't be more helpful, but your girl looks like a sweetheart and most definitely has a lot of Rottweiler blood (even if she turned out not to be 100% purebred) and I'm sure she's a fantastic dog. Enjoy her.
Best of luck with her ~ Sue
