Patrick, can you contact the breeder you purchased him from? A good breeder will take the dog back if you can't rehome him. Please don't take your Fila to a shelter :( That would be the worst thing you could do to him. If I couldn't rehome my dogs and I couldn't keep them I would euthanize them before I would take them to a shelter. If you have facebook there is a mastiff rescue page. Is there someone he knows and trusts that he could stay with until you can find him a home? He is very pretty......I hope you find a home for your boy!!!
