Nine weeks is also really young. Your puppy was recently separated from mom/siblings, has no idea what you want, and is reacting to a new environment and new rules. It takes time. I left the house in the same way that desertsage01 suggested because I had to go to work. Four hours in the crate, lunch break for potty, four hours in the crate (Yes, I had to clean up my fair share of pee swamps and give baths that first month because of this). I can guarantee that my puppy had a fit, but I wasn't home to intervene and screw things up out of guilt or frustration. I'm home now full time since last week and I still do three hours in, lunch break and play time, three hours in (while the kids are at school) just to keep a system going. I can come and go from the kitchen (where the crates are located), do the dishes, work in my office, and our 18 week old is quiet because he's adjusted.
