Yes, it worked for us removing the bed completely. We had the same story, at 4 month he would pee in the bed as soon as he will get there. Otherwise, he would go outside the house. After couple washes and changing 2 beds, I completely removed it and he slept for 3 weeks on the kitchen wood floor. The weather was still warm, so I don't think it was a problem. Now Napoleon almost 5 month and I just got him a new bed. He peed in it as soon as he got there. I washed it and gave him another chance. It is got colder here at night time, so I guess after the first night in the new bed he figured out the difference between sleeping on the floor and sleeping in the bed and no more accidence, so far. I bought the cheep beds from TJ Maxx and will wait until he is at least a year old before buying him a nice bed. Remember, they are still puppies.
