Sorry, this will be long.
I don't know what kind of advice to offer, but we had the same problem with Jake. We got Jake from a pet store. Big Big mistake. Pet stores keep pups in cages and want them to pee in the cage. So of course, Jake was used to peeing in a cage. Once in a crate, which is much smaller and doesn't have a grate on the botton, he would still pee and poop in his crate. It was horrible. He would also pee five or six times outside, and still pee inside right afterward. I must tell you Jake was a real disaster to house break.
This is what we did. Jake would only go in his crate at night, if we were in the room. So that took care of the night and morning. Then the rest of the day, he went EVERYWHERE with us. He never peed in the car, so thats where he went. We were in school then and while we were in class (usually 1 hour), he was in the car waiting. We got Jake in January, so it was winter and the car never got hot. If we were both at work for too long to keep him in the car, I let him run free in the house. I know that seems gross, but we really didn't have a choice. We would just check the house for accidents and clean up.
We also did the umbilical cord thing. Jake was just tied to me everywhere I went. And of course REWARD. Jake got like a million treats any time we went outside.
Once he started to get older, around 5 months old, we were able to start crating him more, but not for too long. He would just freek out, being crated alone, but did eventually stop going potty in it.
One of the best things we did, was regulate Jake's water in take. We don't have a water dish in the house (and still don't). When ever Jake was thirsty, we would take him outside. Water and peeing has now become associated with outside. That really works well.
It took getting Tobee, for Jake to become house broken (around 8 months old) though. Having Tobee crated next to him, Jake finally got used to the crate. And now even sleeps in it at night, even though we don't put him in it any more.
Tobee was so easy to house break. We still crate both of them during the day, if we are not home. Not due to going to the bathroom, but due to distruction.
Hope this helped some. I am not really sure what worked the best with Jake. I think it was mostly age and Tobee, though.
