A few things I've learned throughout the years:

Take Teddy to her designated area immediately after waking or eating. Wait until something happens. Be patient - it could take 10 minutes or more.
Praise profusely.

If Teddy is soiling the crate, the crate is too big. Get a smaller crate.

I'm assuming that Teddy is inside while you are at work with no way to get outside, correct? If so, invest in puppy pads. They are treated with a smell that will attract a dog to that area to relieve themselves. After Teddy becomes old enough to hold it, you'll slowly move it to the door & then outside, if that is the final destination. Patience.

Watch Teddy when she isn't in the crate. The minute you see the action (sniffing, running in a circle) take her to her area (outside, if that will be the final destination.)

When you find an accident, get a rolled up newspaper and walk to the area. Take the newspaper and repeatedly hit yourself in the head while chanting "Bad owner! Bad owner!" OK, that's a joke. Seriously, don't spank when you find an accident. Clean it up & let it go. The dog doesn't associate the spanking with the action, especially at 8 weeks old.

Clean it with a solution that will eliminate the smell. If you have tile, vinegar works well. If it is carpet, you might look into a commercial cleaner for this task. Check Petsmart or some other pet store.
