If your puppy whines or crying at night, you can try following methods:
1. Try moving the crate into your bedroom.
2. Make sure it doesn’t have to go outside to excrete. If so, you need to get up and take it outside.
3. If it whines again, but doesn’t need to go outside, bang your hand on the crate door and say something like “No Crying, Be Quiet” or “No, Sleep Time Now”
4. Try giving it a play toy or chew toy and then simply ignore any continued whining. Also you can give your puppy some snacks and gentlely comforting, it will eventually learn to settle down.
