Is it too late for my dog?

you can try piddle pads. put on down when he goes on it tell him good boy keep moving it closer and closer to the door you wanna take em outside to or you can try and catch him before he pees and scoop him up and make a mad dash for outside when he does go giv him lots of praise.also take him for walks when he goes agan give him lots of praise. when he pees in house tell him in a stern not screaming voice bad or naughty good luck
