New rescue pup pooping in house [View all]

[phylny]

We got a new little guy, about 3 years old, from a rescue a bit over two weeks ago. He's doing well - knows nothing obedience-wise, but he's slowly learning. We've had two pee accidents and tonight was his fourth poop accident. I have had most of the house closed off to him and am opening it up slowly. Here's what I've been doing:

Wake up in the morning, quick potty outside, breakfast, and then an immediate walk where he'll generally pee and poop
Mid-day walk (me or dog walker)
Potty outside when I come home from work
Dinner at 6, immediate walk outside where he'll generally pee and poop (if I can't, I kennel him briefly, then walk)
Potty outside in the evening

I am praising him, "Good potty! Good business!" for #s 1 & 2, like I've always done.

This evening, I fed him dinner and he ate, bolted to the guest bedroom, and immediately pooped. I cleaned it up, didn't say anything (he's lightning fast) and put him in the crate. There he sits. I didn't reprimand him. I had JUST taken him out to pee at 5:30 when I got home, and he peed (reluctantly - I needed to encourage him and stay out with him), but didn't poop.

I'm at a loss. My next idea is to feed him in the crate, assuming if I can't get him outside immediately, he probably (!?!) won't poop in his crate.

Any other ideas are most welcome.
