[oliver&me]

Its been a while since I've been around but I need some advise...

When I first got Oliver I wasn't supposed to have him in my apartment so I trained him to use a potty pad. There wasn't much of a problem with that except now I am in my own house and really would rather train him to go outside. He is just not getting it... I take him out often and he'll pee, but then he just wants to play. He rarely poops outside even if I keep him out there for a long time. When he comes back in he goes in the same spot inside pretty quickly after we get in. I've cleaned the floor with several different cleaners trying to erase the smell but he keeps going back...
I also have my boyfriend's dog living with me who is extremely well trained and will go sit by the door when he needs to go. I would love to get Oliver to do the same!
Any thoughts?????
Oh, I've gone back to putting him in his crate anytime I'm not giving him my undivided attention, but with the other dog walking around I feel like I'm being too mean...
