The Great Dane Chihuahua mix is part of an ongoing effort to produce a new breed with the desirable characteristics of the Great Dane and the Chihuahua canine breeds. What you will get is a whole new Designer breed that is slightly smaller in size than your average Great Dane but way bigger than your miniature Chihuahua canine.
When you choose a mutt or a mixed breed from a shelter home, you are teaching yourchild the act of kindness. You are also, in a way, teaching them about social responsibility that helps a good deal in the longer run.
As a general rule of thumb, always get the mid-size and the larger dogs. These are usually great for family and kids. Avoid smaller dogs, such as Chihuahuas, or anything that you can carry up with one hand.
Since adopting a rescue dog is a lifelong decision, it might be better to get a DIY dog DNA test kit to test for its exact breed composition.
