My vet scans every dog and cat that walk through the doors. I would hope all vet would do this...
I don't let my Yorkies outside without me. They are either on a leash held by me or in their fenced play yard with me right there or at least in the yard where I can see them while doing yard work. If I go in - so do they - if I go to a different part of the yard where I can't see them - they come with or go in the house.
I have thought about those stickers, too. Even the bumper stickers like "I Love My Yorkie." That is just advertising you have them.. or the cute signs you can put in your yard like, - Yorkie Crossing or Guarded by Yorkies. No way would I tell people I own Yorkies like that!
Sad world where you have to be so darn cautious with a dog!!!
Then think of how much worse it is for our skin kids! Geez, we won't even go there...
