I have a 8month rottie mix... when I first got him I tried to potty train him to go outside... but I hardly had the time to take him... so from I got him he was potting in the house on news paper... but when he does that it has the house stink... please help me!! How can I train him to now go outside to potty??

The only way to train him to go outside is with time and patience.
When he goes inside you just need to say "no" and grab him and take him outside straight away...
Also taking him out at regular intervals and praising him when he goes on the grass.
