ELSOL, just wondering if your Yorkie ever lost those extra canines? My Gabi is 11 months and still has double upper canines. I am very annoyed at the Vet because I specifically requested all her baby teeth to be extracted at the time she was spayed. I actually pulled out two on my own afterwards. However, these upper canines are hanging in for good it seems. Guess it won't hurt as long as they look healthy.
