Pet Sitter - Full-time / Part-time

Long term boarding needed for a dog while owner is in a long term addiction recovery program - up to 90 days. Looking for boarding in a 1 hour radius of Mercer, PA or Mount Vernon, OH (43050) for 1 dog. An individual or an actual boarding facility is ok. Oreo is a 70lb pit mix. He gets along well with cats but is dog selective/aggressive so would need to be boarded carefully away from other dogs. Boarding facility does not need to be near Mercer. We are out of ideas on how or where to board him at a low cost & long term instead of surrendering him. I live 3 hours away and have a multi dog household so cannot take him. Food will provided. I would appreciate any offers or advice.
