There is a Facebook Group for this dog, but you have to be approved to join by Dog Gone Recovery. If they personally dislike you or someone you know, they will not approve you. They will also not tell you about expert resources that are available. Those resources are Missing Pet Partnership and Lost Pet Professionals. It is unethical behavior of any group to NOT give this information to owners. For more info about missing dog resources, join the Facebook group https://www.facebook.com/groups/CTLOTDogSearchMgmt/
