Hi. I've had my puppy for about 3 weeks. She whined when she was put in her crate for 2-3 days. And I got no sleep the first week. And I have puppy pads all over. Three days a week she is in her crate for 7 hours. (sometimes I take her to work) I also agree with someone who said tire them out. It really works. When I put Penny in her crate after playing she is napping in no time. She was 8 weeks when I got her. She is awesome and I fell in love. They are alot of work, too. But you have to establish a routine. It worked for me. I was a little upset when she adjusted to her crate. I liked her in my bed. I still let her sleep with me for awhile every night. lol.
