A Rottweiler-Chihuahua mix is a cross between a Rottweiler and a Chihuahua. Mixed-breed dogs can inherit a number of physical and personality traits from either parent, making it difficult to predict which ones will be expressed in the offspring. Researching the characteristics of both parent breeds can help with prediction.
The Rottweiler is a muscular, powerful dog known for its courage, protective tendencies and loyalty. The Chihuahua, in comparison, is one of the smallest dog breeds, but is also loyal and brave. A hybrid of these two breeds would likely display these shared traits in addition to the intelligence both the Rottweiler and the Chihuahua are known for.
