Have you advertised this collie locally? I've had good success with using ads, especially ones that list the dog's breed and/or have a picture. Humor has worked sometimes. Here is an example of one ad I wrote: PLAYFUL, HANDSOME REDHEAD seeks companion for long walks together, riding in your truck, camping, fishing trips and cozy nights by the fire. Ask for Rusty the Retriever puppy at the Smith Animal Shelter; phone # _________.
Good luck in placing her. C J
