Yorkie mixes are a unique hybrid of the two breeds. Both Yorkies and silky terriers have curly coats and long ears, but the Yorkie is considered a toy dog because it’s much smaller than its larger cousin, the silky terrier. While the Yorkie may seem similar to the Yorkie, this crossbreed is not purebred. So when you find yourself trying to identify a Yorkie or a silky terrier mix, just remember that this is a mix between the two breeds.
