My sister had a great tip that she used on her papimo. She didn't want to use the crate for "time outs" when it came to biting because she didn't want her pup to associate being in the crate with being in trouble. She wanted the crate to be a positive experience, not a bad one. So, whenever she was playing with her puppy, she would make sure she had a laundry basket nearby. If puppy bit, my sister would yelp NO and immediately put the laundry basket upside down over the puppy and turn her back away from him or even walk away. she would wait about a minute and then return to playing. She said it worked absolute wonders because puppy associated biting with a quick end to the fun and being under the basket. I plan on using this method too. Hope that helps.
