A Corgi-Yorkie mix is a cross between a Yorkshire terrier and a Welsh corgi. The traits of mixed-breed dogs are hard to predict as they can include a wide spectrum of the parent breeds' physical and personality characteristics.
The Yorkshire terrier is a toy dog known for its high energy level, cleverness and affection. The Welsh corgi is also a small, active dog, so a mix between these two is likely to be small and full of energy. Although Yorkshire terriers are friendly, they can be aggressive to strangers and other animals. Yorkshire terriers are also very vocal and can become unruly if their masters are not firmly in control.
