Best Dog Training Methods

My french bulldog has been house trained for almost a year now. He has not relieved himself in the house in the longest time, and always lets me know when he needs to go out. These past couple days he has done his business indoors. Anyone have any ideas why the sudden change?

Dogs are creatures of habits. Check to see if you changed his habits. It is possible that he can’t go outside to do his business. Keep a fixed schedule of his feedings and walk him outside. It is possible that he could also be sick, check your vet to be sure. Re-train him if all else fail.
