UPDATE - Spoke to the trainer at length. The woman looking is retired, and looking for a young adult female - she would love a retired breeder or rescue. I suggested she register on the various rescue sites but also figured our amazing network would be a good resource as it is!!! I love you people!!
I have a friend who contacted me today (she is a dog trainer) and she has a client who is looking for a Cavalier - Philly area, but I assume they'd be willing to travel a bit if necessary. If you know of any available young adults out there. Thanks (PM me if you have leads).
