At 11 weeks, pups are crazy hyper and will do just about anything. For me, keeping the crated until their around 5/6 month while I'm gone is what works best. I've come a couple times and have even seen everything in their crates turned upside down
Keeping your pup in a crate while your at work isn;'t bad as long as you provide your puppy with exercise and lots of attention when your home
Mine are now 5 months old and they tend to sleep most of the day anyway now. They've gotten into a routine of being crated and using that as naptime...but when i get home..all heck breaks loose as all three run around like crazy with each other for an hour. Its so funny to watch.
After the house is over, they are instant lap dogs. I'm going to need to limit my computer time at night because 3 on my lap these days is gettng a bit much in these chair LOL
