@Baxter Tiberius There will be more advise in a few but first thing I can tell you is take the potty pad out of the crate.
1.Dogs should never be trained to poop or pee in their sleeping area. You need to put the divider in the crate and make it big enough so he can stand up and turn around. Dogs naturally will not poop or pee where they sleep.
2. Puppies between 8-14 weeks needs to be taken out between every 2-3 hours during the night. You need to set your alarm clock to wake you up and take him potty. Even if he doesnt want to wake up take him out.
3. To make the crate a happy place put the crate near your bed when he crys during the night put your fingers in the crate pet or wiggle so he can see you are there dont take him out unless it is potty time.
4. Cover the top and side of the crate with a towel or sheet leave the front open (not covered) so he can see out. It make a cave type atmosphere which dogs love.
5. Before bed time make it fun. Give him a special snack we give ours a half a rice cake with peanut butter and then take him out to potty and wait til he does his business and get excited about once he goes.
Regarding the puppy apartment yah I really dont think that will work with puppies they tend to eat the potty pads and you should never train a dog to go inside the house. They need to learn to hold it or learn to notify you when they need to go. I am sure someone will be by who can advise how to train a dog to go inside a home.
Puppies are a lot of work but with love and patience he will understand the crate is a safe place. Dogs love routine keep at it and he will love his crate.
