Welcome to YT ! PLEASE be very careful with this little dog around your Canes as one wrong step & it could be over for this little one. Also, she(the yorkie) may be intimidated by the SIZE alone of your other dogs. It may not be that she's not socialized to other dogs but the sheer HUGENESS of the Canes in her eyes so just keep that in mind as a lot of small dogs are kept away from large dogs to keep them from being injured. Trust me on this, after you get to know this little one you will fall totally in LOVE with her & the breed & she will most likely NOT be your last Yorkie
