I thought this was a very interesting and informative thread if something happens to the caregiver. I had a couple of Yorkies come into rescue after the caregiver passed away and their children who promised they would take care of the dogs did not want the dogs. We also see Yorkies end up in rescue because there were no plans made for these little ones.
