1st, uve gotta allocate a spot (or several spots) whr he's allow to do his business thr. i would always suggest not to use newspaper. use cloth (the same cloth everytime)
You are going to encourage your dog to pee & poo on your sofa, bed & anything that is fabric!!! for pee & tissue paper for poo. do not scold, punish, scream, beat, hit, abuse ur doggie ok??? wat im suggestin to u is housebreakin thru a more positive way. there is "NO NEED" to say "NO" immediately after he poos/pees, remove the mess with the above said ways. place the mess to the allocated spot/s. carry ur doggie to that spot/s & let him sniff the mess. praise him (pat his head, massage his lower lips, etc but no treats ya) leave him thr for a moment (1~2mins). then only u remove the mess. throw the poo filled tissue paper. rinse the pee stained cloth & let to dry. use the same wet cloth again if u need to. if u did not catch him on the spot while he's pooin/peein, same story. repeat everythin, there is "NO NEED" to say "NO". ur gonna have a smart doggie, dont worry abt it, give urself some confident & persistency. ur doggie will learn his new trick within these 2weeks. remember...patience as well ya
good luck & keep us updated ya
cheers
