Help with our 2 month puppy

Hello all.

Recently we got a puppy named Loki.

We are trying our best to get him potty trained but we have some troubles during the last 4 days. He doesnt have a problem telling at night when he want to go out, he starts moving in his bed and squeeks a bit.

During the day he doesnt do that, without warning he sits down on his bed in the living room and pees, before i can get up its to late unfortunately, then we take him still outside to get the association to pee outside. Today he didn't wanna go outside we have taken him for 20-30 min walk but he doesn't do anything. He walked a bit and then sits down and pulls back to home, after that and being back inside he peed on his bed in the living room, he doesn't do that on his bed in the night.

Any idea why?

We also used treats to lure him, then he comes up to us and takes it and then sits down agian. Every time he peed on his bed in the living room we put it straight away in the washingmachine so he doesn't have the scent association with peeing there, although i happend 3 times in 4 days so far..

When he did it outside we praised him for doing that and then he gets very happy and jumpy

Any tips that help will be very welcome and appreciated 😀

What we already found out so far is that we have to take him outside everytime he wakes up from a nap.
