A very old stray {The Old Fella Story}

Anyone on here know of an Australian Cattle Dog rescue group that deals with Northeast Ohio?? My girlfriend found a dog running around the parking lot of a grocery store almost two weeks ago. Being the softie she is she gathered him up and took him home. Mind you, the same evening she brought him home she was having a halloween party for 11 girls, all about 9 years old. She also has 2 dogs of her own. She has done everything that a person normally does to try and find his owners but no one has contacted her. She cannot keep him just because she already has 2 fairly large dogs and a small house. He is house trained, knows sit, stay, lay down and also gives a paw. He would not get on the couch (which is changing since he sees her dogs doing it) so obviously he has been trained and was cared for. He also gets along great with her 2 dogs and had a blast with all of the girls. The only no kill in the area is full. From his size, looks and "smartness" I would say he has cattle dog/blue healer in him. She has also stated that she has no problems fostering him until he can find a forever home. Also, is there anyone here who has access to put a dog on Petfinder? He is a sweet dog. I told her I would reach out and do what I can.
